Terms and expressions connected with ships, shipping, seamanship and navigation From Wikipedia, the free encyclopedia
This glossary of nautical terms is an alphabetical listing of terms and expressions connected with ships, shipping, seamanship and navigation on water (mostly though not necessarily on the sea). Some remain current, while many date from the 17th to 19th centuries. The word nautical derives from the Latin nauticus, from Greek nautikos, from nautēs: "sailor", from naus: "ship".

A Second World War personal flotation device used to keep people afloat in the water; named after the 1930s actress Mae West, well known for her large bosom.
The first voyage of a ship in its intended role, i.e. excluding trial trips.
Maierform bow
A V-shaped bow introduced in the late 1920s which allowed a ship to maintain a given speed with less power, improved seakeeping, increased reserve buoyancy, reduced pitching movements, and improved propeller immersion to increase performance in rough seas.
A sail control line that allows the most obvious effect on mainsail trim. Primarily used to control the angle of the boom, and thereby the mainsail, this control can also increase or decrease downward tension on the boom while sailing upwind, significantly affecting sail shape. For more control over downward tension on the boom, a boom vang may be used.
mainstay
The stay running from the top of the mainmast to the bottom of the foremast, or from the top of the foremast to the ship's stem.
To have all of the crew of a sailing vessel not required on deck to handle the ship go aloft and spread out along the yards. Originally used in harbors to display the whole crew to harbor authorities and other ships present to show that the vessel's guns were not manned and hence her intentions were peaceful, manning the yards has since become a display used in harbor during celebrations and other special events.
1.A soldier trained for service afloat in a (primarily) infantry force that specializes in naval campaigns and subordinated to a navy or a separate naval branch of service rather than to an army. Often capitalized (e.g. a Marine or the Marines). Notable examples are the United Kingdom's Royal Marines, formed as the Duke of York and Albany's Maritime Regiment of Foot in 1664 with many and varied duties including providing guard to ship's officers should there be a mutiny aboard, and the US Marine Corps, formed in 1775 as a separate naval service alongside the US Navy. It is incorrect, and often viewed by marines as offensive, to refer to a marine as a "soldier" or "infantryman", as these terms refer to personnel of an army rather than those of a marine force. It also is incorrect, and sometimes considered offensive by both merchant mariners and marines, to refer to merchant mariners as "merchant marines", because merchant mariners are civilian sailors responsible for operating merchant ships and are not marines. Marines sometimes are thought by seamen to be rather gullible, hence the phrase "tell it to the marines", meaning that one does not believe what is being said.
2.An alternative term for a navy, uncommon in English but common in other languages.
3.Of or pertaining to the sea (e.g. marine biology, marine insurance, marine salvage).
4.A painting representing a subject related to the sea.
An hourglass-like timekeeping instrument used aboard ships from at least the 14th century until reliable mechanical timepieces replaced it in the early 19th century. Marine sandglasses measured the passage of time in 30-minute increments to regulate time on watch, to measure a boat's speed, and to assist in determining a ship's position by measuring the time elapsed while she was on a given course.
A vertical pole on a ship that supports sails or rigging. If a wooden multi-part mast, this term applies specifically to the lowest portion.
mast case
A yachtsman's tabernacle. The iron fitting in which the heel of the mast is mounted.[2]
Mast partner
The reinforced area of the deck surrounding the hole through which a mast passes as it rises from its step (usually on the keel) to the above-deck area[3]
mast step
The place in the hull where the lowest point of a mast rests, taking the weight of the mast and the thrust imposed by the tension of the rigging, and preventing lateral and fore and aft movement of the bottom of the mast. With a wooden hull and mast, this is usually achieved by having a socket cut in the top of the keelson, a floor or some other major structural component. A tenon cut into the bottom of the mast sits snugly in the socket.[4] With a deck-stepped aluminium mast, the step may consist of a metal fitting bolted to the deck, to which bolts a matching fitting at the bottom of the mast.
A small platform partway up the mast, just above the height of the mast's main yard. A lookout is stationed here, and men who are working on the main yard will embark from here. See also crow's nest.
masthead light
A white running light displayed at the front of a vessel.
A traditional Royal Navy term for an ordinary sailor.
material
Military equipages of all descriptions for the naval services. The bombs, blankets, beans, and bulletins of the Navy and Marine Corps. Taken from Nelson's British navy as the US services became professional. See also materiel – military supplies, equipment and weapons.
A collective term for all merchant ships registered in a given country and the civilians (especially those of that nationality) who man them; the ships and personnel in combination are said to constitute that country's merchant marine. Called the merchant navy in the United Kingdom and some other countries.
merchant mariner
A civilian officer or sailor who serves in the merchant marine. Sometimes such personnel are incorrectly called "merchant marines", but both merchant mariners and marines frown on this term; although merchant mariners are part of the merchant marine, they are civilians and are not in any way marines, which are a specialized type of military personnel.
A name bestowed upon the merchant marine of the United Kingdom by King George V, and since adopted by some other countries as well. The merchant navy's personnel are civilians, and the term "merchant navy" does not imply that they or their ships are a part of the navy. Synonymous with the term merchant marine.
A system of catering in which a standard ration is issued to a mess supplemented by a money allowance, which the mess may use to buy additional victuals from the purser's stores or elsewhere. Each mess was autonomous and self-regulating. Seaman cooks, often members of the mess, prepared the meals and took them, in a tin canteen, to the galley to be cooked by the ship's cooks. As distinct from "cafeteria messing" where food is issued to an individual hand, which is now the general practice.
A measurement of the initial static stability of a vessel afloat, calculated as the distance between her center of gravity and her metacenter. A vessel with a large metacentric height rolls more quickly and therefore more uncomfortably for people on board; a vessel with a small metacentric height will roll sluggishly and may face a greater danger of capsizing.
The portion of the triangular trade pattern of the late 16th through the early 19th centuries in the Atlantic Ocean in which slaves were transported from Africa to the Americas. In the terminology of the slave trade itself, the Middle Passage linked the First Passage (the delivery from Europe of the trade goods to be used to purchase slaves) with the Final Passage (the shipment of the products of slave plantations–sugar, tobacco, cotton–to the markets of Europe).
middles
The middle brails on the mainsail, higher than the lowers, and lower than the mains.[2]
midship house
A superstructure built over the midships section of the hull, often housing the bridge and officers quarters, as well as passenger quarters aboard cargo liners. A common feature of tankers, cargo liners, and cargo ships up until the mid-20th century, when ship design moved away from the use of midship houses.
1.During the 17th century, a naval rating for an experienced seaman.
2.From the 18th century, a naval commissioned officer candidate.
3.From the 1790s, an apprentice naval officer.
4.From the 19th century, an officer cadet at a naval academy.
5.In contemporary British usage, a non-commissioned officer below the rank of lieutenant. Usually regarded as being "in training" to some degree. Also known as "Snotty". It is "the lowest form of rank in the Royal Navy" where he has authority over and responsibility for more junior ranks, yet, at the same time, relying on their experience and learning his trade from them.
6.In contemporary American usage, a cadet of either sex at the United States Merchant Marine Academy or the United States Naval Academy, or under contract and having sworn the Oath of Office in the Navy Reserve Officer Training Corps (NROTC) program. When plural (midshipmen), the term refers to the student body of either academy, and more formally as "the Regiment of Midshipmen" for the Merchant Marine Academy and "the Brigade of Midshipmen" for the Naval Academy, or for the NROTC unit members usually organized into battalions.
midshipman's hitch
An alternative to the Blackwall hitch, preferred if the rope is greasy. Made by first forming a Blackwall hitch and then taking the underneath part and placing it over the bill of the hook.[5]
A self-contained explosive device intended to damage or sink surface ships or submarines, designed to be placed in water and left to wait until they are triggered by the approach of, proximity of, or contact with a surface ship or submarines.
A vessel designed or equipped to detect and destroy individual mines. It differs from a minesweeper, which is designed or equipped to clear areas of water of mines without necessarily detecting them first.
A vessel designed or equipped to clear areas of water of mines without necessarily detecting them first. It differs from a minehunter, which is designed or equipped to detect and destroy individual mines.
misstay
To be "in irons" (i.e. to lose forward momentum) when changing tack.
2.A mizzen staysail is an occasional lightweight staysail on a ketch or yawl, set forward of the mizzenmast while reaching in light to moderate airs.[2]
3.A mizzenmast is a mast on a ketch or yawl, or spritsail barge. Its positioning afore of abaft the rudder post distinguishes between a ketch or a yawl. On a barge its rig determines if she is a muffie or a mulie.[2]
A massive structure, usually of stone or concrete, used as a pier, breakwater, or causeway between places separated by water. May have a wooden structure built upon it and resemble a wooden pier or wharf, but a mole differs from a pier, quay, or wharf in that water cannot flow freely underneath it.
molgogger
1.A type of roller fairlead, also known as a cage roller, with vertical and horizontal rollers, mounted on the bulwark or gunwale and used to constrain and guide a fishing net or towing cable for a net or minesweepingparavane.[8][9]
2.A removable or folding vertical bar or hook fitted to the bulwarks of a tug on either side to prevent the towline moving too far forward, which can endanger stability. Sometimes fitted with a roller. Also called a Norman pin.[10]
1.A turreted ironcladwarship of the second half of the 19th century characterized by low freeboard, shallow draft, poor seaworthiness, and heavy guns, intended for riverine and coastal operations.
2.In occasional 19th-century usage, any turreted warship.
3.A shallow-draft armored shore bombardment vessel of the first half of the 20th century, designed to provide fire support to ground troops, often mounting heavy guns.
5.(river monitor) A monitor specifically designed for riverine operations, used during the 19th and 20th centuries and more recently than other types of monitor. River monitors generally are smaller and lighter than other monitors.
monkey bridge
A high platform above the wheelhouse offering better visibility to the operator while maneuvering.
A ball woven out of line used to provide heft to heave the line to another location. The monkey fist and other heaving-line knots were sometimes weighted with lead (easily available in the form of foil used e.g. to seal tea chests from dampness) although Clifford W. Ashley notes that there was a "definite sporting limit" to the weight thus added.
A vessel that leads, serves, or carries smaller vessels, in the latter case either releasing them and then proceeding independently or also recovering them after they have completed a mission or operation. A mother ship sometimes contrasts with a tender, which often (but not necessarily) is a vessel that supports or cares for larger vessels.
A type of motor-powered sailing vessel, typically a yacht, that can derive power from its sails or engine, independently of each other and often with both at the same time (motorsailing)
motorsailing
Proceeding under the power of sails and engines at the same time. In a yacht this is usually to windward and may be found more comfortable than using just sails or engines on their own.[11]
A template of the shape of the hull in transverse section. Several moulds are used to form a temporary framework around which a hull is built.
moulded
(of a timber in a wooden hull) The identifier of a measurement of a timber in a wooden hull, used, together with sided, instead of width and thickness which could be ambiguous–length, the third dimension is not ambiguous. Moulded identifies the measure across the surface of an individual timber where one side of that surface is shaped to fit the overall hull shape, as determined by the moulds. Therefore this is the dimension across the vertical sides of a keel, the athwartships face of a frame, or the fore and aft face of stem or stern post.[12]
moulded beam
moulded breadth
The breadth of the hull lines at the widest point, normally at midships and measured inside the hull planking or plating. Used in some systems of tonnage measurement.[13]
moulded depth
The distance between the horizontal plane of the top of the keel and the top of the main deck beams at the edge of the hull. Compare with freeboard depth.[3]
moulded dimensions
Dimensions of a ship shown by the lines plan, generally excluding planking thickness and shell thickness.[13]
moulded draft
moulded draught
Draught measured relative to the base line.[13] Compare with keel draught.
mould loft
Where the lines of the ship are drawn out full-size and the templates for the timbers are made.
mousing
Several turns of light line around the mouth of a hook, to prevent unhooking accidents.[2]
A cargo ship that has fittings to carry standard shipping containers and retractable tweendecks that can be moved out of the way so that the ship can carry bulk cargo.
An exercise conducted by the crew of a ship prior to embarking on a voyage. Passengers are required to participate in the drill so that they can be instructed how to evacuate safely in the event of an emergency on board the ship.
muster station
A specific location on a vessel planned as a gathering place during an emergency or a muster drill. If a person is believed missing, all passengers must report to their muster station for a head count.
A ship whose name also is used to refer to her entire class of ships. Usually but not always the first ship of her class to be completed and enter service, in which case the term name ship can be used as a synonym for lead ship.
A body of water protected from the weather by virtue of its being mostly surrounded by land, and deep enough to provide anchorage for the vessels using it.
A map of a sea or ocean area and adjacent coastal regions, intended specifically for navigation at sea. Nautical charts use map projections designed for easy use with hand instruments, such as the Mercator projection, and indicate depths, hazards, landmarks, aids to navigation such as buoys, and ashore facilities of interest to mariners. Nautical charts are generally originally published by government agencies such as the U.S. National Oceanic and Atmospheric Administration, and are now provided in both print form and digital for use in chartplotters.
A unit of length corresponding to approximately one minute of arc of latitude along any meridian arc. By international agreement, it is equivalent to exactly 1,852 metres (6,076ft; 1.151mi).
naval programme
The British system of authorizing naval construction by an annual bill in Parliament.
naval infantry
1.Sailors subordinated to a navy trained and equipped to operate ashore temporarily as an organized infantry force, but at other times responsible for the normal duties of sailors aboard ship.
2.A specialized, permanent force of troops subordinated to a navy and responsible for infantry operations ashore. Although more specialized than sailors trained to operate temporarily as naval infantry and bearing similarities to a marine force or marine corps, such permanent naval infantry forces often lack the full capabilities of a marine force. Naval infantry forces also usually differ from marine forces in being subordinated directly to a navy rather than to a separate branch of naval service such as a marine corps.
All activities related to determining, plotting, and tracking the position and course of a ship in order to keep track of its position relative to land while at sea. Navigation charts have been used since ancient times, and remain in use as back-ups to modern satellite-based positioning systems. Numerous map projections including the common Mercator projection were developed specifically to make navigation at sea simple to perform with straight-edges and compasses.
Rules of the road that provide guidance on how to avoid collision and also used to assign blame when a collision does occur.
nay
A reply in the negative, synonymous with "no". The opposite of "aye".
net cutter
1.(Fisheries patrol), also trawlwire cutter: A device employed by the Icelandic Coast Guard during the "Cod Wars" to cut the trawling wires of foreign fishing trawlers working within Iceland's claimed exclusive fisheries zones.
2.(Submarine): A device, sometimes powered by explosives, mounted on the bow of a submarine to cut through anti-submarine netting.
3.(Torpedo): A scissors-like or pistol-powered device on the nose of a torpedo intended to assist the torpedo in breaking through torpedo nets.
A term used for a ship trading between England and ports east of the Cape of Good Hope for the English Company Trading to the East Indies, a new company chartered in 1697 to compete with the "old" East India Company. The term fell into disuse when the two companies merged in 1707.[14]
night boat
(United States) A type of steamboat that provided sleeping quarters for passengers on overnight voyages, as opposed to a day boat that had no need of such facilities.
nipper
A short rope used to bind a cable to the "messenger" (a moving line propelled by the capstan) so that the cable is dragged along, too (used where the cable is too large to be wrapped around the capstan itself). During the raising of an anchor, the nippers were attached and detached from the (endless) messenger by the ship's boys. Hence the term for small boys: "nippers".
The entire ship's company was expected to witness floggings, assembled on deck. If it was very crowded, the bosun might not have room to swing the cat o' nine tails (the whip).
A type of navigational buoy, often cone-shaped, but if not, always triangular in silhouette, colored green in IALA region A or red in IALA region B (the Americas, Japan, Korea, and the Philippines). In channel marking its use is opposite that of a "can buoy".
Any material, often tarred hemp fibres picked from old untwisted ropes, used for caulking gaps or seams between the planks of hulls.
oar
A pole, usually of wood, with a blade at one end and a handle at the other, which is pivoted on a fulcrum on the side of a boat to provide propulsion by pushing the blade through the water.[15]
oar crutch
A metal (or sometimes plastic) fitting that acts as the fulcrum point of an oar. It usually takes the form of a U-shape, with a pin underneath the bottom of the "U". The pin rotates in a socket in the boat's gunwale, and the oar rests in the "U".[16] See also rowlock.[11]
The part of a naval vessel containing the residential quarters and wardroom for commissioned officers. Officer's country is off-limits to enlisted personnel unless they are there on official business.
Said of a vessel making a voyage without being carried aboard another vessel; e.g. "the yacht crossed the ocean on her own bottom", or in the plural, "yachts rarely cross the ocean on their own bottoms".
on station
A ship's destination, typically an area to be patrolled or guarded.
on the beach
1.A Royal Navy term that means "retired from the Service."[17]
1.A seaman in the British Royal Navy in the 18th century who had between one and two years of experience at sea. Later, a formal rank in the Royal Navy for the lowest grade of seaman, now obsolete.
2.The second-lowest rank in the United States Navy from 1797 to 1917, between landsman and seaman. Renamed "seaman second class" in 1917.
2.Situated within a vessel but positioned away (or farther away, when contrasted with another item) from her centerline.
3.Farther from the hull of a ship; e.g. "the larger boat was tied up alongside the ship outboard of the smaller boat".
4.Farther from the pier or shore; e.g. "the tanker and cargo ship were tied up at the pier alongside one another with the tanker outboard of the cargo ship".
A motor mounted externally on the transom of a small boat. Outboard motors are often mounted in a way that makes them easily movable, such that the boat may be steered by rotating the whole motor with respect to the boat's bearing, instead of or in addition to using a rudder.
1.Generally, any structure projecting from the side of a vessel.
2.Any contraposing float rigging beyond the side of a vessel to improve the vessel's stability.
3.A thin, long, solid hull used to stabilize the inherently unstable main hull of an outrigger canoe or a sailboat.
4.A variety of structures projecting from a keelboat by which the running rigging may be attached outboard of the hull.
5.A pole or series of poles projecting from a fishing vessel that allow the vessel to trawl with more fishing lines in the water without the lines tangling and allowing lures and bait to simulate a school of fish.
6.A triangular frame on a rowboat or galley that holds the rowlock away from the saxboard or gunwale to optimize leverage for the rowers. Also called a rigger.
outward bound
To leave the safety of port, heading for the open ocean.
Adult sailors were flogged on the back or shoulders while tied to a grating, but boys were beaten instead on the posterior (often bared), with a cane or cat o' nine tails, while bending, often tied down, over the barrel of a gun, known as kissing the gunner's daughter.
overbear
To sail downwind directly at another ship, stealing the wind from its sails.
overboard
Off or outside a vessel. If something or someone falls, jumps, or is thrown off of a vessel into the water, the object or person is said to have gone overboard. See man overboard.
overfalls
Dangerously steep and breaking seas due to opposing currents and wind in a shallow area, or strong currents over a shallow rocky bottom.
overhead
The ceiling of any enclosed space below decks in a vessel, essentially the bottom of the deck above.
overhaul
Hauling the buntline ropes over the sails to prevent them from chafing.
A large and distinctive type of foremast installed aboard Imperial Japanese Navybattleships and battlecruisers during modernization and reconstruction of the ships in the 1930s. A pagoda mast was created by strengthening a ship's existing tripod foremast and adding platforms to it for searchlights, lookouts, shelters, and other structures, giving the mast the appearance of a pagoda temple.
painter
A rope attached to the bow of a vessel, used to make the vessel fast to a dock or a larger vessel, including when towed astern.[19]
The pulsation in and out of the bow and stern plating as the ship alternately rises and plunges deep into the water.
paravane
1.(weapon) A device stabilized by vanes that functions as an underwater glider and is usually streamed from the bow of a vessel and towed alongside, intended to cut the mooring of submerged mines or otherwise destroy them.[20]
2.(water kite) A towed underwater object with hydrofoils, of use in commercial and sport fishing, water sports, marine exploration, and military operations, sometimes equipped with sensors and also of use in exerting a sideward holding force on a vessel. Also called a water kite.
parbuckle
A method of lifting a roughly cylindrical object such as a spar. One end of a rope is made fast above the object, a loop of rope is lowered and passed around the object, which can be raised by hauling on the free end of rope.
A movable loop or collar, used to fasten a yard or gaff to its respective mast. A parrel still allows the spar to be raised or lowered and swivel around the mast. It is sometimes made of wire or rope and fitted with beads to reduce friction.
part brass rags
Fall out with a friend. From the days when cleaning materials were shared between sailors.
A type of very light and shallow Spanish sailing vessel of the 15th through 18th centuries with two masts, resembling a cross between a brig and a schooner. Originally a type of warship, but later in use as a trading vessel.
pawls
Small bars used to stop the barrel of a winch or capstan moving backward under an increased load or if the turning power was reduced. In early capstans, the pawls had to be manually moved in and out of the notches in which they worked. Later capstans had automatic pawls that dropped into notches as the barrel turned. In breaking out an anchor, a crew would "heave and pawl" if the bow was rising and falling with the waves, so giving a varying load on the cable.[21]
pay off
1.To let a vessel's head fall off from the wind (to leeward).[2]
2.During the Age of Sail, the practice of paying a crew its wages for the voyage when a vessel completed her voyage, at which point the crew was said to be paid off.
3.In British and Commonwealth usage, to decommission a warship, e.g. "The old destroyer paid off after returning to port at the end of her final cruise."
paying
Filling a seam (with caulking or pitch), lubricating the running rigging; paying with slush, protecting from the weather by covering with slush. See also the devil to pay.
paymaster
The officer responsible for all money matters in Royal Navy ships including the paying and provisioning of the crew, all stores, tools, and spare parts. See also purser.
pea coat
Heavy topcoat originally made from pilot cloth.[22] Officers and chief petty officers wear a variation with gold buttons called a reefer or a longer model called a bridge coat.
peace cruiser
U.S. Navy term of the early 20th century for obsolete cruisers and gunboats used in policing and diplomatic roles.[23]
peak
1.The upper aftermost corner of a fore-and-aftsail; used in many combinations, such as peak-halyards, peak-brails, etc.[2]
2.The narrow part of a vessel's bow, or the hold within it.
A hook with a hinge in the curve of the hook, normally held closed by a metal ring that keeps the two hinged parts together. Can be instantly released by knocking the ring along the hook so that it frees one of the hinged parts which swings open and releases whatever the hook is holding. Often seen on opening sections of guard rails and life-raft lashings, but also used on more heavily loaded components.[11][24]
pendant
1.A length of wire or rope secured at one end to a mast or spar and having a block or other fitting at the lower end.
A raised structure, typically supported by widely spread piles or pillars, used industrially for loading and unloading commercial ships, recreationally for walking and housing attractions at a seaside resort, or as a structure for use by boatless fishermen. The lighter structure of a pier contrasts with the more solid foundations of a quay or the closely spaced piles of a wharf. In North America, the term "pier" used alone connotes either a pier used (or formerly used) by commercial shipping or one used for fishing, while in Europe the term used alone connotes a recreational pier at a seaside resort.
pier-head jump
When a sailor is drafted to a warship at the last minute, just before she sails.
A highly specialized form of rope ladder, typically used to embark and disembark pilots over the side of a ship. Sometimes confused with Jacob's ladders, but the design and construction of pilot ladders is governed tightly by international regulation and includes spreaders – elongated versions of the standard machined step – rather than the type of steps generally found on Jacob's ladders.
The pin or bolt on which a ship's rudder pivots. The pintle rests in the gudgeon.
pipe (bos'n's)
Also bosun's call.
A whistle used by boatswains (bosuns or bos'ns) to issue commands. Consisting of a metal tube that directs the breath over an aperture on the top of a hollow ball to produce high-pitched notes. The pitch of the notes can be changed by partly covering the aperture with the finger of the hand in which the pipe is held. The shape of the instrument is similar to that of a smoking pipe.
pipe down
A signal on the bosun's pipe to signal the end of the day, requiring lights (and smoking pipes) to be extinguished and silence from the crew.
piping the side
A salute on the bosun's pipe(s) performed in the company of the deck watch on the starboard side of the quarterdeck or at the head of the gangway, to welcome or bid farewell to the ship's captain, senior officers, and honoured visitors.
An act of robbery or criminal violence at sea by the occupants of one vessel against the occupants of another vessel (and therefore excluding such acts committed by the crew or passengers of a vessel against others aboard the same vessel). Piracy is also distinguished from privateering, which is authorized by national authorities and therefore a legitimate form of war-like activity by non-state actors.
A vessel's motion, rotating about the beam/transverse axis, causing the fore and aft ends to rise and fall repetitively.
pitchpole
To capsize a boat stern over bow, rather than by rolling over.
pivotting
To turn a sailing barge in shallow water by dropping the leeboard so it drags in the mud, then putting the helmhard over. The maneuver is often used to enter congested harbours.
A special marking, positioned amidships, that indicates the draft of the vessel and the legal limit to which the vessel may be loaded for specific water types and temperatures.
British term for the German Navy's Deutschland-classcruisers, which entered service in the 1930s. The ships had battleship-like armament and armor but were of cruiser size and faster than battleships of the time and were intended to serve as commerce raiders. Classified by the German Navy as Panzerschiffe ("armored ships").
point
A unit of bearing equal to the angle made by 1⁄32 of a circle, i.e. 11.25 degrees. A turn of 32 points is a complete turn through 360 degrees.
The course of a sailing vessel in relation to the direction of the wind, divided into six points: in irons (pointed directly into the wind), close hauled (sailing as close into the direction of the wind as possible), close reach (between close hauled and beam reach), beam reach (perpendicular to the wind), broad reach (wind behind the vessel at an angle), and running downwind, running before the wind, or simply running (wind directly behind the vessel).
Overhead diagram of the traditional points of sail. The black arrow at the top represents the direction of the wind. A) in irons; B) close hauled; C) beam reach; D) broad reach; E) running downwind. A sixth point of sail, between B and C, is not depicted: close reach. The red-striped area is the "no sail zone", because it is impossible to sail directly into the wind.
A 17th-century sailing vessel commonly seen in the Mediterranean, similar to a xebec with two or three masts; two-masted polaccas were known as brig-polaccas and three-masted polaccas as ship-polaccas or polacca-settees. Polacca-settees had a lateen sail on the foremast, a European-style square rig on the mainmast, and a gaff or lateen on the mizzenmast.
A high deck on the aft superstructure of a ship. The deck forms a roof over the "poop cabin" in the aft of the ship.[26]
pooped
1.(of a ship or boat) to have a wave break over the stern when travelling with a following sea.[27] This contingency, that can cause significant damage to the ship, is also referred to as "pooping".[28]
1.(facility): A maritime facility on a sea coast, in an estuary, or on a river with loading areas at which a vessel can bring aboard or discharge cargo or passengers.
2.A place along a coast or riverbank where a vessel can take shelter, often including loading and unloading facilities for vessels.
3.A city or town associated with a such a facility or sheltering area.
4.(direction): The left side of a ship or vessel when facing forward (formerly larboard). Denoted with a red light at night.[2]
5.Toward the left-hand side of the ship when facing forward (formerly "to larboard").
6.(rowing): A sweeprower who rows with one oar on one side of a boat and primarily on the port (left) side of the boat.
The port listed in a vessel's registration documents and lettered on her stern. Often used incorrectly as a synonym for home port, meaning the port at which the vessel is based, but it may differ from the port of registry.
port tack
When sailing with the wind coming from the port side of the vessel. Vessels on port tack must give way to those on starboard tack.
porthole
Also simply port.
An opening in a ship's side, especially a round one for admitting light and air, fitted with thick glass and, often, a hinged metal cover, used as a window.
portolan
An obsolete form of nautical chart used prior to the development of lines of latitude and longitude that indicated distances and bearing lines between ports.
The British term used from the second half of the 18th century until 1817 for a sixth rateship-rigged sailing warship armed with 20 to 26 guns, smaller than a frigate but large enough to require a post-captain as her commanding officer.
A small room/closet area in the hull of the ship used for storing gunpowder in barrels, or "kegs", usually located centrally so as to have easy access to the grated loading area. Sometimes may be an enclosed closet with a door, so it can be locked and only the captain would have the key, similar to how rum is stored.
The license given to a ship to enter port on assurance from her captain that she is free from contagious disease. A ship can signal a request for pratique by flying a square solid-yellow flag. The clearance granted is commonly referred to as free pratique.
A term used retrospectively after 1906 for a wide variety of steam battleships built between the 1880s and c. 1905 designed with only a few large guns for long-range fire, relying on an intermediate secondary battery used at shorter ranges for most of their offensive power, and having triple-expansion steam engines. They were rendered obsolete by the revolutionary dreadnought battleships, which began to appear in 1906 and differed from predreadnoughts in having steam turbine propulsion and an "all-big-gun" armament layout in which the ship's primary gun power resided in a primary battery of its largest guns intended for use at long range, with other gun armament limited to small weapons intended for close-range defense against torpedo boats and other small warships.
Formed body of personnel from a ship of the Royal Navy (either a ship seeking personnel for its own crew or from a "press tender" seeking men for a number of ships) that would identify and force ("press") men, usually merchant sailors, into service on naval ships, usually against their will.
preventer
Also gybe preventer and jibe preventer.
A sail control line originating at some point on the boom leading to a fixed point on the boat's deck or rail (usually a cleat or pad eye) used to prevent or moderate the effects of an accidental jibe.
In British usage, a Principal Naval Transport Officer is a shore-based flag officer or captain responsible for sea transport duties, and for assisting the Senior Naval Officer in the preparation of naval orders and conducting disembarkations.
A vessel used as a prison, often to hold convicts awaiting transportation to penal colonies; particularly common in the British Empire in the 18th and 19th centuries.
In British usage, a commissioned warship in active service that is not being used as the flagship of a flag officer. The term does not imply in any way that the ship is privately owned.
1.The forwardmost part of a vessel's bow above her waterline.
2.An alternative term for the bow of a vessel, sometimes used poetically.
puddening
Fibres of old rope packed between spars or used as a fender.[29]
pulling
(of an oar, as used at sea) using an oar for propulsion of a boat where each person (of several) uses one oar. This contrasts with rowing (at sea), where each person uses two oars, one each side of the boat. See row for a full explanation of the complexities of the strict definitions.[30]:135
A flat-bottomed boat with a square-cut bow designed for use in small rivers or other shallow water and typically propelled by pushing against the riverbed with a pole. In this way it differs from a gondola, which is propelled by an oar.
The person who buys, stores, and sells all stores on board ships, including victuals, rum, and tobacco. Originally a private merchant, latterly a warrant officer.
1.In merchant marine usage, the seaman responsible for steering a ship. In naval usage, additional duties in running the ship's routine are included.[31]
2.US Navy enlisted rating (QM) who, in addition to the above duties, assists with the navigation of the ship.[32][31]
The standing orders governing the British Royal Navy issued in the name of the current Monarch.
quay
1.A stone or concrete structure on navigable water used for loading and unloading vessels, generally synonymous with a wharf, although the solid foundations of a quay contrast with the closely spaced piles of a wharf. When "quay" and "wharf" are used as synonyms, the term "quay" is more common in everyday speech in the United Kingdom, many Commonwealth countries, and Ireland, while "wharf" is more commonly used in the United States.
An electronic system designed to transmit radio signals and receive reflected images of those signals from a "target" in order to determine the bearing and distance to the target. The term is an acronym for "radio detection and ranging".
radar reflector
A special fixture fitted to a vessel or incorporated into the design of certain aids to navigation to enhance their ability to reflect radar energy. In general, these fixtures materially improve the visibility for use by vessels with radar.
A flat structure used for support or transportation over water, lacking a hull and kept afloat by buoyant materials or structures such as wood, balsa, barrels, drums, inflated air chambers such as pontoons, or extruded polystyrene blocks.
1.A weapon consisting of an underwater prolongation of the bow of a vessel to form an armored beak, intended to be driven into the hull of an enemy vessel in order to puncture the hull and disable or sink that vessel.
2.An armored warship of the second half of the 19th century designed to use such a weapon as her primary means of attack.
3.To intentionally collide with another vessel with the intention of damaging or sinking her.
4.To accidentally collide bow-first with another vessel.
range
1.To lay out a rope or chain on deck in a zig-zag or (for rope) a figure‐eight pattern (as opposed to in a coil) so that it can run freely. The zig-zag pattern may be described as flakes.[11][31]
2.The difference between the heights of the high and low tides – a figure that will vary from place to place and day to day.[31]
3.The distance from an observer to a target, such as in gunnery.[31]
1.In British usage, a junior enlisted member of a country's navy; i.e., any member of the navy who is not an officer or warrant officer.
2.In contemporary U.S. Navy and U.S. Coast Guard usage, rating is the occupational specialty of an enlisted member of the service, rate denotes enlisted pay grade, and rank generally applies to commissioned officer pay grades.
The rungs fastened between the shrouds permanently rigged from bulwarks and tops to the mast to form rope ladders enabling access to the topmasts and yards.[2]
Sailing across the wind; i.e. bearing anywhere between about 60° and 160° relative to the direction from which the wind is blowing. Reaching can be further subdivided into "close reaching" (about 60° to 80°), "beam reaching" (about 90°), and "broad reaching" (about 120° to 160°). Compare beating and running.
reaching sail
A sail specifically designed for tighter reaching legs. Reaching sails are often used in racing with a true wind angle of 35 to 95 degrees. They are generally used before the wind angle moves aft enough to permit spinnakers to be flown.
A government official whose duty is to give owners of shipwrecks the opportunity to retrieve their property and ensure that law-abiding finders of wrecks receive an appropriate reward.
receiving hulk
Also receiving ship.
A hulk used in harbor to house newly recruited sailors before they are assigned to a crew.
Red Duster
A traditional nickname for the Red Ensign, the civil ensign flown by civilian vessels of the United Kingdom.
A British flag flown as an ensign by certain British ships. Since 1854, it has been flown by British merchant ships (except for those authorized to fly the Blue Ensign) as the United Kingdom's civil ensign. Prior to 1864, ships of the Royal Navy's Red Squadron also flew it, but its naval use ended with the reorganisation of the Royal Navy in 1864.
A phrase used as a mnemonic to remember that the navigational standard for a vessel entering ("returning to") a port in the Americas (excluding Greenland), Japan, South Korea, and the Philippines is for her to steer so that red-marked navigational aids lie to starboard (to the "right") of an observer facing forward on the vessel, while green-marked aids must lie to port (i.e. to the "left"). This contrasts with the rest of the world, where the standard is the opposite, i.e. green markers must lie to starboard and red ones to port.
red-to-red
A passage of two vessels moving in the opposite direction on their port sides, so called because the red navigation light on one of the vessels faces the red light on the other vessel.
1.(noun) Rock or coral that is either partially submerged or fully submerged but shallow enough that a vessel with a sufficient draft may touch or run aground.
2.(verb) To temporarily reduce the area of a sail exposed to the wind, usually to guard against adverse effects of strong wind or to slow the vessel.[2]
reef-points
Lengths of rope attached to a sail and used to tie up the part of a sail that is taken out of use when reefed. In older systems, such as square or gaff rigs, the reef points take some of the load on the sail and distribute it to the boltrope; with slab reefing, the reef-points just keep the sail fabric controlled in a tidy manner. Reef points may either be sewn to each side of the sail or passed through eyelets.[27][11][35]
reef-bands
Long pieces of rough canvas sewn across the sails to give them additional strength.
A series of boat races, usually of sailboats or rowboats but occasionally of powered boats.
regular ship
A term used by the British East India Company from the 17th to the 19th centuries for merchant ships that made "regular voyages" for the company between England (later the United Kingdom) and ports east of the Cape of Good Hope, a trade over which the company held a strict monopoly. The company chartered most of its ships; "regular ships" were those under long-term charter, and the company kept their operations under tight control. A set of "regular ships" set off for Asian ports during each sailing season (September through April), and returned up to two years later. The status and role of "regular ships" differed from that of ships the company referred to as chartered ships, country ships, extra ships, and licensed ships.[14]
A bearing relative to the direction in which the vessel is pointing or traveling; the angle between the vessel's forward direction and an object, as measured clockwise from the bow. See also absolute bearing.
A collection of naval vessels fully equipped for service but partially or fully decommissioned because they are not currently needed. In the modern United States, a reserve fleet is sometimes informally called a ghost fleet. During the Age of Sail and well into the 19th century, ships in a reserve fleet were said to be in ordinary.
a type of jam of the rope on a winch drum: the heavily loaded part of the rope unintentionally rises over the successive turns on the winch, so stopping them from moving.[37]
The process of restoring a capsized vessel to upright condition.
righting couple
righting moment
The force that tends to restore a ship to upright equilibrium once a heel has altered the relationship between the vessel's center of buoyancy and center of gravity.
An area of persistent strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 50 degrees south. During the Age of Sail, ships took advantage of the Roaring Forties to speed their trips, and yacht sailors still do today.
Any unusually large wave for a given sea state; formally, a wave whose height is more than twice the significant wave height of that sea state (i.e. the mean of the largest third of waves in a wave record).
1.The side-to-side motion of a vessel as it rotates about the fore-aft (longitudinal) axis. Listing is a lasting, stable tilt, or heel, along this longitudinal axis.
2.Another name for the longitudinal axis itself (e.g. the "roll axis").
roller
rolling swell
Swell that has increased in height due to influence of the bottom in shallow water, but before it is high enough to break.[31]
1.A period, traditionally on Wednesday afternoons, when a tailor boarded a sailing warship while the vessel was in port; the crew was excused from most duties and had light duty mending uniforms and hammocks and darning socks. When the ship was at sea, the crew similarly was excused from most duties on Wednesday afternoons to engage in mending chores. Wednesday afternoons, like Sundays, thus were a more social time when crewmen rested from normal duties, similar to a Sunday, and, because the crew used rope yarn for mending, Wednesday afternoon became known as rope yarn Sunday.
2.After uniforms began to require less care, and through the mid-20th century, a period on Wednesday afternoons when naval crew members were excused from their regular duties to run personal errands.
3.Since the mid-20th century, any period of free time when a naval crew is given early liberty or otherwise excused from its normally scheduled duties.
2.(more precisely, as used at sea) to propel a boat with oars, where each rower handles two oars, one on each side of the boat. This contrasts with the inland waters definition. When, at sea, a person is working just one oar, this is termed pulling[30]:135
2.(more precisely, as used at in inland waters) to propel a boat with oars, where each rower uses just one oar. On inland waters, one person using two oars, one on each side of the boat, is termed sculling[30]:135
1.The cutout in the washstrake of a boat into which an oar is placed, so providing a fulcrum when the oar is in use.[41]
2.A common term for an oar crutch, the u-shaped metal fitting, with a pin underneath that fits in a socket in the gunwale of a boat to provide the fulcrum for an oar.[11] See also thole pin.
royal
1.On large sailing ships, a mast right above the topgallant mast.
A steering device that is placed aft and pivoted about a (usually vertical) axis to generate a yawing moment from the hydrodynamic forces that act on the rudder blade when it is angled to the flow of water over it. There are several types of rudder, which generally divide into outboard or inboard. An outboard rudder is hung (hinged) on the stern of the vessel. An inboard rudder has a stock which passes through a gland in the hull, with the structure of the hull continuing towards the stern above the rudder. A spade rudder is hinged solely on the stock and has no lower bearing to help take the loads. Other rudder types may be hinged on an extension of the keel or on a skeg. Rudders may be balanced, by having some of the blade extend in front of the stock. On simple watercraft, the rudder may be controlled by a tiller—essentially, a stick or pole attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, the rudder is often linked to a steering wheel via cables, pushrods, or hydraulics.
The structural part of a rudder that transmits the torque created by the tiller or steering gear to the rudder blade. It may consist of a steel tube which passes through bearings in the hull above the rudder, or with a stern-hung rudder, is the structure carrying all or some of the pintles or gudgeons on which the rudder pivots.
ruffle
A serrated iron ring attached to the barrel of the anchorwinch and to which the pawl is applied to prevent backruns of the anchor chain.[2]
1.A place or room for the stowage of cargo in a vessel.
2.The act of stowing cargo aboard a vessel.
3.To arrange (cargo, goods, etc.) in the hold of a vessel; to move or rearrange such goods; the pulling and moving about of packages incident to close stowage aboard a vessel.
4.To search a vessel for smuggled goods, e.g. "The customs officers rummaged the ship."
rummage sale
A sale of damaged cargo (from French arrimage).
run
1.The stern of the underwater body of a ship from where it begins to curve upward and inward.
Sailing more than about 160° away from the direction from which the wind is blowing (i.e. moving in the same or nearly the same direction as the wind). If moving directly away from the wind, it is called a dead run. Compare reaching and beating.
running backstays
A backstay that can be released and moved out of the way so that it does not interfere with sails or spars on the leeward side. On tacking, the new windward running backstay must be set up promptly to support the mast.[2]
running gear
1.The propellers, shafts, struts, and related parts of a motorboat.
A condition in which the hull of a vessel deflects downward so the ends of the keel are higher than the middle. The opposite of hogging. Sagging can occur when the trough of a wave is amidships or during loading or unloading of a vessel and can damage her or even break her in half.
1.A piece of fabric attached to a vessel and arranged such that it causes the wind to drive the vessel along. Sails are typically attached to the vessel and manipulated by sailors via a combination of mast, spars, and ropes.
2.The power harnessed by a sail or sails to propel a vessel.
3.To use sail power to propel a vessel.
4.A trip in a boat or ship, especially a sailboat or sailing ship.
5.In American usage, a tower-like structure on the dorsal (topside) surface of submarines constructed since the mid-20th century. A submarine's sail is similar in appearance to a fabric sail or fin, and is referred to as a fin in British and Commonwealth usage. It also superficially resembles the conning tower of submarines built before the mid-20th century, but differs from a conning tower in that a submarine conning tower contained instruments and controls for the periscopes to direct the submarine and launch torpedo attacks, while a submarine sail (or fin) does not perform these functions.
sail drive
A non-steerable drive leg fitted through the bottom of a sailboat carrying a propeller. Compare azimuth thruster and sterndrive.
A craftsman who makes and repairs sails, working either on shore in a sail loft or aboard a large, oceangoing sailing ship.
sailorman
London term for a sailing barge, or a bargeman.[2]
sally ship
A method of freeing a vessel grounded on mud, in which the crew forms a line and runs back and forth athwartships to cause her to rock back and forth, breaking the mud's suction and freeing her with little or no damage to the hull. When this is required, the crew is given the order "Sally ship!"
saloon
A social lounge on a passenger ship.
saltie
Great Lakes term for a vessel that sails the oceans.
salty dog
Slang for a sailor, especially for a seaman in the navy.
A relatively flat-bottomed Chinese wooden boat from 3.5 to 4.5 metres (11 to 15ft) long, generally used in coastal areas or rivers and as traditional fishing boats. Some have a small shelter, and they may be used as a permanent habitation on inland waters. It is unusual for sampans to sail far from land as they are not designed to survive rough weather.
sampson post
A strong vertical post used to fasten the anchor cable or mooring warps, for towing another vessel, or to support a ship's windlass, the heel of a ship's bowsprit, the base of a cargo derrick or any other heavy load. In a smaller vessel, is usually fastened to the keel at its lower end.[27][11]
sandsucker
A barge that collects sand from the bottom of lakes.
SB
S.B.
Prefix for "sailing barge", used before a ship's name.
scandalize
To reduce the area and efficiency of a sail by expedient means (slacking the peak and tricing up the tack) without properly reefing, thus slowing boat speed. Also used in the past as a sign of mourning.
A type of sailing vessel characterized by the use of fore-and-aft sails on two or more masts with the forward mast being no taller than the rear masts. First used by the Dutch in the 16th or 17th century. A topsail schooner has a square topsail (and may also have a topgallant) on the foremast.
A type of barge either converted from a schooner or purpose-built as a barge with a schooner rig, primarily in use from the 1860s to the 1940s, initially on the Great Lakes and later in salt-water environments as well. A schooner barge required a smaller crew than a schooner and needed to be towed, but under favorable conditions could hoist sails to reduce fuel consumption by the vessel towing her.[43][44]
1.A method of preparing an anchor for tripping by attaching an anchor cable to the crown and fixing to the ring by a light seizing (also known as becue). The seizing can be broken if the anchor becomes fouled.
2.A type of clinker dinghy, characteristically beamy and slow.
3.An inland racing boat with no keel, a large sail plan, and a planing hull.
1.(v.) In sport or recreational rowing, especially on inland water, to propel a boat by oars, where each of one or several persons uses two oars, one on each side of the boat. This contrasts with the maritime traditional working boat or naval usage, where this activity is called rowing.[30]:135
2.(v.) To propel a boat with a single oar resting in a notch at the stern, using a figure of eight motion of the blade of the oar, which is continuously immersed in the water
4.(n.) A boat propelled by sculling, generally for recreation or racing
scuppers
Originally a series of pipes fitted through a ship's side from inside the thicker deck waterway to the topside planking in order to drain water overboard, with larger quantities drained through freeing ports, which were openings in the bulwarks.
scuttle
1.A small opening, or lid thereof, in a ship's deck or hull.
2.To sink a vessel deliberately.
scuttlebutt
1.A barrel with a hole in it, used to hold water that sailors would drink from. By extension (in modern naval usage), a shipboard drinking fountain or water cooler.
A stabilizer deployed in the water for heaving to in heavy weather. It acts as a brake and keeps the hull in line with the wind and perpendicular to the waves. Often in the form of a large bag made of heavy canvas. See also drogue.
sea chest
A watertight box built against the hull of the ship communicating with the sea through a grillage, to which valves and piping are attached to allow water in for ballast, engine cooling, and firefighting purposes. Also, a wooden box used to store a sailor's effects.
The general condition of the free surface on a large body of water with respect to wind waves and swell at a certain location and moment, characterized by statistics, including the wave height, period, and power spectrum. The sea state varies with time, as the wind conditions or swell conditions change.
The testing phase of a boat, ship, or submarine, usually the final step in her construction, conducted to measure a vessel's performance and general seaworthiness before her owners take delivery of her.
seaboat
1.A ship's boat kept ready for immediate use at sea, and used, for example, for retrieving a man overboard, or taking a boarding party to another vessel. Usually rigged with patent disengaging gear that allows both falls to be released simultaneously and quickly, so enabling the boat to be launched from a ship with way on.[46]
2.A term used for any vessel when assessing her physical behavior at sea. A vessel that performs well in challenging weather or sea conditions such as heavy seas is a good seaboat, while one which does not is a bad seaboat.
A valve in the hull of a vessel used to allow seawater into or out of the vessel. Seacocks are used to admit seawater for purposes such as cooling an engine, feeding a saltwater faucet, or scuttling a vessel, or to drain a sink or toilet into the sea. On warships, seacocks may be used to flood ammunition magazines with seawater to prevent them from exploding during a fire.
The ability of a watercraft to remain seaworthy in the conditions she encounters while underway. A vessel with a good seakeeping ability is very seaworthy even in rough weather.
sea-kindly
(of a boat or ship) Having a comfortable motion in rough seas[47]
A licensed member of the deck department of a merchant ship, third – or, on some ocean liners, fourth – in command; a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer and in charge of maintaining distress-signaling equipment. On oil tankers, the second mate usually assists the chief mate with tank-cleaning operations.
see you on the one
Also CUOTO.
Used principally by pilots and river tug and barge deck and officer crew as a friendly farewell (similar to the phrase "catch you later") or more properly used in vessel to vessel VHF (or when needed ship's whistle) communication, along with its companion phrase "see you on the two" to indicate which side a head-to-head vessel crossing is going to occur. The correct response to the challenge is to repeat it back to the apposing vessel in agreement, and if not in agreement to ask for an alternative arrangement. The "on the one" indicates a single whistle sound signal, or port to port crossing, whilst "on the two" is a dual (two) whistle sound signal, or starboard to starboard crossing. In the US, a "one whistle" or port to port crossing is the normal and preferred crossing side.
seekers
London term for sailing barges that sought cargo, carrying cargo for other merchants at a fee, rather than for the owner.[2]
A merchant ship that can unload herself with no assistance from harbor facilities is self-sustaining, while a ship that needs harbor facilities to unload is non-self-sustaining. Self-sustaining ships are more expensive to build, maintain, and operate than non-self-sustaining ships, but have the advantage of being able to operate in less-developed ports that lack infrastructure.
self-unloader
Great Lakes slang term for a vessel with a conveyor or some other method of unloading the cargo without shoreside equipment.
An advanced type of predreadnoughtbattleship of the very early 20th century with an "all-big-gun" armament of mixed calibers. A semi-dreadnought differed from a conventional predreadnought, which had only a few large guns for long-range fire and relied on an intermediate secondary battery used at shorter ranges for most of her offensive power, but also differed from a dreadnought battleship, which dispensed with an intermediate secondary battery in favor of an all-big-gun main battery of the same caliber for use at long range. A semi-dreadnought had greater firepower at longer ranges than a conventional predreadnought, but lacked the long-range firepower of a dreadnought.
sennet
Cord formed by plaiting rope-yarn by hand. There are many types of plait, which may be flat, round, or square in section, and many uses.[49][31]
sennet whip
A summary punitive implement.
serve
Cover a rope or splice by wrapping with thin line to protect it.[2] Compare with whipping
set
The direction toward which the current flows.

(of a ship or boat): sink lower in the water, often prior to sinking altogether.
A navigational instrument used to measure a ship's latitude.
shackle
U-shaped iron, with a screw pin at the open end used for securing stays to sails, allowing easy removal.[2]
shaft
1.A propeller shaft. The term shaft can be used instead of "propeller" to describe the number of propellers a ship has, e.g., The ship has two shafts or The ship's engines drive three shafts.
A cruise performed before a ship enters service or after major changes such as a crew change, repair, or overhaul during which the performance of the ship and her crew are tested under working conditions.
shakes
Pieces of barrels or casks broken down to save space. They are worth very little, leading to the phrase "no great shakes".
A rope attached to the clew and used to control the setting of a sail in relation to the direction of the wind. The sheet is often passed through a tackle before being attach to fixed points on the deck, or in the case of a barge, to a traveller on the main horse.[2]
sheet anchor
Historically, the heaviest anchor aboard a sailing ship, to be used only in case of emergency, and located amidships. In more general usage, the term has come to mean a person or thing that is very reliable in times of emergency.[52] For example, during the first inauguration of Thomas Jefferson, he advocated, "the preservation of the General [Federal] Government in its whole constitutional vigor, as the sheet anchor of our peace at home and safety abroad."[53]
An extremely narrow, and often disproportionately long, rowing boat outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats, specifically designed for racing or exercise.
shelter deck
An upper deck having no overhead protection from the weather itself, but sheltering the deck below it.
shift colors
1.Changing the flag and pennant display when a moored vessel becomes underway, and vice versa. A highly coordinated display that ships take pride in; the desired effect is that of one set of flags vanishing while another set flashes out at precisely the same time.
2.Slang for changing out of one's Navy uniform into civilian clothes to go ashore. (The US Navy's newsletter for retired personnel is nicknamed Shift Colors for this reason.)[55]
Sighting the positions of the Sun and Moon using a sextant, using a nautical almanac to determine the location and phase of the Moon, and calculating the relative effect of the tides on the navigation of the ship.[56][57]
2.More generally, any medium or larger seagoing vessel. Smaller vessels or those used in sheltered waters are generally called boats. Exceptions include submarines which are always referred to as boats.[59]
3.To send (an item or cargo) via waterborne transport, or in the derived meaning, by any means of transport (such as rail).[60]
Also ship classification organisation or ship classification organization
A non-governmental organization that establishes and maintains technical standards for the construction and operation of ships and offshore structures.
A type of sailing warship constructed from the 1600s through the mid-1800s to serve as part of the line of battle; one of the largest and most powerful warships of the era.
Striking the ship's bell is the traditional method of marking time and regulating the crew's watches. Each bell (from one to eight) represents a 30-minute period since the beginning of a four-hour watch. For example, in the classical system, "Three bells in the morning watch" represents 90 minutes since the beginning of the morning watch, or 5:30 AM. "Eight bells" indicates the end of a watch.
The number of persons in a ship's crew, including officers.
ship's husband
A legal term for an agent based on land, who has authority to make repairs and attend to the management, equipment, and general management of a ship in the home port.[61][62]
All aspects of maintenance, cleaning, and general upkeep of the hull, rigging, and equipment of a ship. It may also be used to refer to aspects of maintenance which are not specifically covered by the technical departments.[63][64]
2.The body of ships belonging to one country, port, or industry.
shipshape
Meticulously neat and tidy. A sailor is expected to keep his or her quarters shipshape, with all items arranged neatly and securely, both to save space aboard ship and because of the danger posed by loose objects if the ship encounters turbulent seas.
A facility where ships or boats are built and repaired. Routinely used as a synonym for dockyard, although dockyard is sometimes associated more closely with a facility used for maintenance and basing activities, while shipyard sometimes is associated more closely with a facility used in construction.
An especially shallow draught on a vessel, making the vessel capable of sailing in unusually shallow water.
shore leave
Free time given to officers and crew of a naval vessel when they are off duty and allowed to disembark and spend time on land. See also liberty.
short stay
The relative slackness of an anchor chain; "short stay" means the chain is somewhat slack, and neither vertical nor fully extended.
shorten
1.To take in the slack of (a rope).
2.To reduce (sail) by taking it in, e.g. "shorten sail".
shot across the bow
A shot fired close to and in front of a moving vessel to warn her to stop, often for boarding.
show your true colors
To display the correct flag ("colors") for your ship's sovereign allegiance after using a false or misleading flag, or flying no flag at all, to approach an unsuspecting enemy ship.
One of an even-numbered group of seamen posted in two rows on the quarterdeck when a visiting dignitary boards or leaves the ship, historically to help (or even hoist) him aboard.
sided
(of a timber in a wooden hull) The identifier of a measurement of a timber in a wooden hull, used, together with moulded, instead of width and thickness which could be ambiguous–length, the third dimension is not ambiguous. Sided identifies the measure across the surface of an individual timber which is at right angles to the moulded direction. Therefore this is the dimension across the top of a keel, the fore and aft face of a frame, or the athwartships face of stem or stern post.[65]
(of the arrangement of oars on a boat) having only one oarsman seated on each thwart, operating one oar on one side of the boat, with the oars alternating between port and starboard along the length of the boat. This contrasts with double-banked, where two oarsmen are seated on each thwart, each of whom operates one oar on their side of the boat. A third arrangement is to have one rower on each thwart working two oars, one on each side of the boat.[30]:135
single up
to reduce the number of mooring lines to a minimum immediately prior to getting under way. In a small vessel this would usually be a reduction to a mooring line at just the bow and the stern. In a larger vessel this may be a reducton to headrope, sternrope and two springs.[66]
A ship of the same class as, and therefore virtually identical in design and appearance to, another ship. Sister ships share an identical or nearly identical hull and superstructure layout, similar displacement, and roughly comparable features and equipment. Often, sister ships become more differentiated during their service lives as their equipment (and, in the case of military ships, their armament) are separately altered.

A mooring rope that is intended to be the last to be released when getting under way and is arranged so that it can be released from on-board. An example of this would be a rope that is led from the ship (or boat), through a ring on a mooring buoy, and then back to the ship.[70]
A ramp on the shore by which ships or boats can be moved to and from the water. Slipways are used for building and repairing ships and boats. They are also used for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage.
In modern usage (from circa 1850s), a single-masted fore and aft sailing rig with one headsail set on the forestay, and a mainsail abaft the mast. The sloop rig is very common in modern leisure sailing vessels. In older usage, a sloop may have more than one headsail, but with the jib (the outer headsail) also set on a stay. This differentiates from a cutter of the same era, where the jib would be set flying and a running bowsprit was used. Any bowsprit that might be fitted on a sloop was part of the standing rigging and remained in place at all times.[71]

square meal
A sufficient quantity of food. Meals on board ship were served to the crew on a square wooden plate in harbor or at sea in good weather. Food in the Royal Navy was invariably better or at least in greater quantity than that available to the average landsman. However, while square wooden plates were indeed used on board ships, there is no established link between them and this particular term. The OED gives the earliest reference from the US in the mid-19th century.
A generic type of sail and rigging arrangement in which the primary driving sails are carried on yards that are perpendicular, or "square", to the keel of the vessel and to the masts. A ship mainly so rigged is said to be square-rigged.[48]
Yards held rigidly perpendicular to their masts and parallel to the deck. This was rarely the best trim of the yards for efficiency but made a pretty sight for inspections and in harbor. The term is applied to situations and to people figuratively to mean that all difficulties have been resolved or that the person is performing well and is mentally and physically prepared.
The phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure under its keel that reduces the ship's buoyancy, particularly at the bow. The reduced buoyancy causes the ship to "squat" lower in the water than would ordinarily be expected, and thus its effective draught is increased.
To the purist, a prefix for Screw Steamer (i.e. with screw propulsion, meaning propellers). It is used before the name of a ship. Compare with "PS", which stands for "Paddle Steamer". Widely used as an abbreviation for "Steam Ship".

tacking duels
In sailboat racing, on an upwind leg of the race course, the complex manoeuvres of lead and overtaking boats to vie for the aerodynamic advantage of clear air. This results from the ongoing strategy of the lead boat's effort to keep the following boat(s) in the blanket of disturbed bad air he is creating.

A small, fast, cheap naval vessel of the latter part of the 19th century and first half of the 20th century designed to carry torpedoes into combat, thus threatening much larger warships. Replaced during the second half of the 20th century by the fast attack craft.
A heavy net a ship could deploy around herself using booms or spars while at anchor, moored, or otherwise stationary to protect herself from torpedo attack. A torpedo net hung at a distance from the hull sufficient to detonate a torpedo without significant damage to the ship. Torpedo nets first appeared in the late 1870s and were used through the World War I era, and they were used again during World War II.
touch and go
1.The bottom of the ship touching the bottom, but not grounding.
2.Stopping at a dock or pier for a very short time without tying up, to let off or take on crew or goods.
3.The practice of aircraft on aircraft carriers touching the carrier deck and taking off again without dropping hooks.
towing
The operation pulling a vessel or equipment through the water by means of lines.[31]
A decorative board at the bow of a vessel, sometimes bearing the vessel's name.
training ship
A ship used to train students as sailors, especially a ship employed by a navy or coast guard to train future officers. The term refers both to ships used for training at sea and to old, immobile hulks used to house classrooms.
The shipping trade on the spot market in which the vessels involved do not have a fixed schedule or itinerary or published ports of call. This contrasts with freight liner service, in which vessels make regular, scheduled runs between published ports.
British term for a room located in the interior of a ship containing computers and other specialised equipment needed to calculate the range and bearing of a target from information gathered by the ship's spotters and range finders. These were designated "plotting rooms" by the United States Navy.[97]
1.A lateral member fastened inside the sternpost, to which the hull and deckplanks are fitted.[2]
2.The aft "wall" of the stern; often the part to which an outboard unit or the drive portion of a sterndrive is attached.
3.A more or less flat surface across the stern of a vessel. Dinghies tend to have almost vertical transoms, whereas yachts' transoms may be raked forward or aft.
Transom stern
A stern which ends in a vertical "wall," or transom, a flat area that extends from the waterline or a point above the waterline up to the deck.
1.Small fittings that slide on a track, rod, or line. The most common use is for the inboard end of the mainsheet.
2.A more esoteric form of traveller consists of "slight iron rings, encircling the backstays, which are used for hoisting the top-gallantyards, and confining them to the backstays".[92]
An iron ring that moves on the main horse on a sailing barge. It is fitted with an eye onto which is hooked the main sheet, of the loose-footed mainsail.[2]
A wooden peg, pin, or dowel used to fasten pieces of wood together, such as the hull, gunwales, thwarts, etc.[92]
trial trip
A (usually short) voyage for a new ship to test its capabilities and ensure that everything is functioning correctly. A new ship will usually have one or more trial trips before embarking on its maiden voyage.
A historical term for a pattern of trade among three ports or regions in which each port or region imports goods from one of the other two ports or regions in which there is no market for its exports, thus rectifying trade imbalances between the three ports or regions as well as allowing vessels to take the best advantage of prevailing winds and currents along the three trade routes. The best known example is the Atlantic triangular trade pattern of the late 16th through the early 19th centuries, in which vessels carried finished goods from northeastern North America or Europe to Africa, slaves from Africa to the Americas, and cash crops and raw materials from the Americas to either northeastern North America or Europe.
trice
To lift up something by means of a rope running through a block set above it, to get it out of the way. Most commonly used in tricing up the tack of a loose-footed gaff sai to reduce sail area and (sometimes) to give better visibility to the helmsman.[11][98]
trick
A period of time spent at the wheel, e.g. "my trick's over".
trim
1.The relationship of a ship's hull to the waterline.
2.Adjustments made to sails to maximize their efficiency.
A person responsible for ensuring that a vessel remains "in trim" (that the cargo and fuel are evenly balanced). An important task on a coal-fired vessel, as it could get "out of trim" as coal is consumed.
A type of mast introduced aboard warships in the first decade of the 20th century, consisting of three large cylindrical tubes or columns supporting a raised platform for lookouts and fire control equipment and later for radar antennas and receivers. In succeeding decades, tripod masts replaced the earlier pole masts and lattice masts. Tripod masts persisted in some navies until the 1960s, when plated-in structures began to replace them, and in other navies until the early 2000s, when stealth designs began to move away from any type of open mast.
tripping line
A buoyed line attached to the crown of an anchor to facilitate breaking it out.
Any ship used to carry soldiers. Troopships are not specially designed for military operations and, unlike landing ships, cannot land troops directly onto a shore; instead they unload troops at a harbor or onto smaller vessels for transportation to shore.
1.A circular disc or rectangle of wood or a wooden ball- or bun-shaped cap near or at the top of a wooden mast, usually with holes or sheaves in it through which signal halyards can be passed. Trucks are also used on wooden flagpoles to keep them from splitting. The main truck is located on the main mast, the mizzen truck on the mizzen mast, and so on.[88]
A counter stern that has been truncated to provide a kind of transom. It may have windows, serving a large aft stateroom. Popular on larger cruising yachts.
truss
The rope or iron used to keep the center of a yard to the mast.
A hull shape, when viewed in a transverse section, in which the widest part of the hull is someway below deck level.
tuna clipper
A fishing boat based on the United States West Coast and used for commercial tuna fishing. A typical tuna clipper is diesel-powered, has her deckhouse forward and her bait tanks aft, and is outfitted with iron racks around her stem from which her crew uses heavy bamboo poles to fish for tuna.
A rope passing behind or around an object such as a cleat, bollard or winch drum, usually with the purpose of controlling the rope.[99] See also riding turn
turn to (turn two)
A term meaning "get to work", often hand-signed by two fingers and a hand motion in turning fashion.
1.Originally (in the mid-to-late 19th century), a rotating, enclosed, armored, cylindrical box with guns that fired through gunports. Turret-equipped ships contrasted sharply with those equipped with barbettes, which in the second half of the 19th century were open-topped armored rings over which rotating gun(s) mounted on a turntable could fire.
2.Since the late 19th century, an enclosed, armored, rotating gunhouse mounted above a barbette, with the gun(s) and their rotating turntable mounted in the barbette protected by the gunhouse; in 20th- and 21st-century usage, this generally is any armored, rotating gun installation on a warship.
turtleback deck
A weather deck that has a distinct convex rounded over shape, similar to the back of a turtle. Used on ships of the whaleback type and on the forward weather deck of torpedo boats."[100]
In dinghy sailing especially (but also in other boats), a boat is said to be "turtling" or to "turn turtle" when the boat is fully inverted with the mast pointing near vertically downwards, but may remain floating.[upper-alpha 1][101][102][103]
A deck on a general cargo ship located between the main deck (or weather deck) and the hold space. A general cargo ship may have one or two tweendecks (or none at all).
tweendeck space
The space on a tweendeck available for carrying cargo or other uses.
A command used to co-ordinate a group of people pulling on a rope. Originally a sailing navy term referring to the two members of a gun crew (numbers two and six) who ran out the gun by pulling on the ropes that secured it in place.
two blocks
When the two blocks in a tackle have become so close that no further movement is possible as in chock-a-block.[2]
tye
A chain or rope used for hoisting or lowering a yard. A tye runs from the horizontal center of a given yard to a corresponding mast and from there down to a tackle. Sometimes more specifically called a chain tye or a rope tye.[88]
A measurement of the empty space in large tanks or holds for bulk solids. Used to determine quantity of material in tank for volume and stability calculations. Often used in place of sounding for tanks which may carry more viscous or aggressive liquids; or if the tank is extremely deep.
A method employed by navies to transfer fuel, munitions, and stores from one ship to another while underway. Sometimes abbreviated as UNREP.
U.N.P.O.C.
An abbreviation for "Unable to navigate, probably on course"; a 19th-century term used in log books of vessels left without accurate navigational guidance due to poor visibility and/or proximity to the North Pole (where magnetic compasses are difficult or impossible to use). Dropped out of common usage in the 1950s with improvements in maritime navigational aids.
2.To remove an oar or mast from its normal position.
up-and-down
The description given to the position of the anchor chain, usually used when the anchor is being raised and indicating that the chain has been hauled in tightly such that the vessel is floating directly above the anchor, which is just about to be broken out of the ground. Used more rarely to refer to a situation where the anchor chain is slack and hangs vertically down from the hawsepipe.[31]
up-behind
An order to slack off quickly and run slack to a belaying point. This order is given when a line or wire has been stopped off or falls have been four-in-hand and the hauling part is to be belayed.
1.A line leading from the gaff to either side of the deck, used to prevent the gaff from sagging.[88]
2.One of a pair of ropes leading from the deck to the head of a spritsail. It steadies the sprit and can be used to control the sail's performance during a tack. The vang fall blocks are mounted slightly afore the main horse while rolling vangs are extra preventers which lead forward to keep the sail to leeward in heavy weather.[2]
A method of supply of seaborne vessels by helicopter. Abbreviated VERTREP.
very good
very well
An affirmative response given by a senior to the report of a junior, e.g. if the helmsman reports, "Rudder is amidship, sir," an officer might respond, "Very good" or "very well."[31]
vessel
Any craft designed for transportation on water, such as a ship or boat.
vessel of opportunity
A vessel not normally used for a specific function, but available and suitable for temporary application, often requiring temporary fitting or loading of necessary equipment.
viol
Also voyl.
A large rope used to unmoor or heave up the anchor.[108]
Colored cloths or sheets hung around the outside of a ship's upper works, both fore and aft, and before the cubbridge heads, used as an adornment during ceremonious occasions and as a visual screen during times of action in order to protect the men aboard.
A thicker strake, consisting of a wooden plank or group of planks, in the outer skin of the hull, running in a fore-and-aft direction, to provide extra stiffening in selected regions.[4]
1.The living quarters of a naval ship that are designated for the use of commissioned officers other than the captain.
2.A collective term for the commissioned officers of a naval ship excluding her captain; e.g. "The captain rarely referred to his wardroom for advice, and this led to their discontent".
warm the bell
Royal Navy slang from the Age of Sail for doing something unnecessarily or unjustifiably early. Holding a half-hour marine sandglass used until the early 19th century to time watches under one's coat or in one's hand to warm it allegedly expanded the glass's neck to allow the sand to flow more quickly, justifying ringing the bell rung every half-hour to announce the passage of time on watch earlier than if the glass was cold, hence warming the bell and shortening the length of the watch.[110]
warp
1.To move a vessel by hauling on a line or cable that is fastened to an anchor or pier, especially so as to move a sailing ship through a confined or restricted space such as in a harbour.[111]
Also combatant ship, a ship that is built and primarily intended for naval warfare, typically belonging to the armed forces of a state, usually a navy. Unlike a merchant ship, which carries cargo or passengers, a warship carries only weapons, ammunition, and supplies for its crew. An auxiliary warship is a merchant ship taken into naval service and armed for use as a warship. The term battleship sometimes is used as a synonym for warship, but this is incorrect, as battleship has a far narrower meaning and refers only to a specific type of warship.
wash
The waves created by a moving vessel. Not to be confused with wake.
washstrake
An additional strake fastened above the level of the gunwale of an open boat to increase the freeboard.[112]
The allocation of crew or staff to specific roles on a ship in order to operate it continuously. These assignments, known as watches, are divided into regularly scheduled work periods of several hours or longer to ensure that some portion of the crew is always occupying the roles at all times. Those members of the crew who are on watch at a given time are called watchkeepers.
A watercraft used to provide transportation on a scheduled service with multiple stops, usually in an urban environment, analogous to the way a bus operates on land. It differs from a water taxi, which is a similar watercraft that provides transport service to various locations on demand rather than on a predetermined schedule, analogous to the way a taxicab operates on land, although in North America these terms are often used interchangeably. A water bus also differs from a ferry, which usually refers to a watercraft that shuttles between only two points.
A watercraft used to provide transportation on demand to various locations, usually in an urban environment, analogous to the way a taxicab operates on land. It differs from a water bus, which is a similar watercraft that provides transportation on a scheduled service with multiple stops rather than at the rider's will, analogous to the way a bus operates on land, although in North America these terms are often used interchangeably. A water taxi also differs from a ferry, which usually refers to a watercraft that shuttles between only two points.
2.A strake of timber laid against the frames or bulwarkstanchions at the margin of a laid wooden deck, usually about twice the thickness of the deck planking.
way
Speed, progress, or momentum, or more technically, the point at which there is sufficient water flow past a vessel's rudder for it to be able to steer the vessel (i.e. when the rudder begins to "bite", sometimes also called "steerage way".) To "make way" is to move; to "have way on" or "to have steerage way" is to have enough speed to control the vessel with its rudder; to "lose way" is to slow down or to not have enough speed to use the rudder effectively. "Way enough" is a coxswain's command that the oarsmen stop rowing and allow the boat to proceed by its existing momentum.
way-landing
An intermediate stop along the route of a steamboat.
way-lay
The verb's origin, from wegelage, means "lying in wait, with evil or hostile intent". So to be waylaid refers to a ship that has been taken off its course, route, or way by surprise, typically by unfortunate or nefarious means. In Herman Melville's 1851 novel Moby-Dick, the great white whale waylaid the Pequod and sank it, with only a few souls surviving in lifeboats.[113]
A location defined by navigational coordinates, especially as part of a planned route.
ways
The timbers of shipyard stocks that slope into the water and along which a ship or large boat is launched. A ship undergoing construction in a shipyard is said to be on the ways, while a ship scrapped there is said to be broken up in the ways. Also known as a slipway.
The tendency of a sailboat to turn to windward in a strong wind when there is no change in the rudder's position. This is the opposite of lee helm and is the result of a dynamically unbalanced condition. See also center of lateral resistance.
A British term used in the 18th and 19th centuries for any merchant sailing ship making voyages between the Old World and the West Indies or the east coast of the Americas, in contrast to an East Indiaman, which made voyages to the East Indies or South Asia. The term most frequently was applied to British, Danish, Dutch, and French ships.
wet
(of a ship) Prone to taking water over her decks at sea. For example, a ship that tends to take water over her bow can be said to be "wet forward."
1.A type of cargo steamship of unusual design formerly used on the Great Lakes of North America, notably for carrying grain or ore. The hull continuously curved above the waterline from vertical to horizontal, and when the ship was fully loaded, only the rounded portion of her hull (the "whaleback" proper) was visible above the waterline. With sides curved in towards the ends, whalebacks had a spoon-shaped bow and a very convex upper deck.
2.A type of high-speed launch first designed for the Royal Air Force during World War II, or certain smaller rescue and research vessels most common in Europe that, like the Great Lakes vessels, have hulls that curve over to meet the deck, although the "whaleback" designation comes not from the curve along the gunwale as in the Great Lakes vessels, but from the fore-and-aft arch in the deck.
3.A sheltered portion of the forward deck on certain British fishing boats designed, in part, so that water taken over the bow is more easily shed over the sides. The feature has been incorporated into some pleasure craft – aboard which it is known as a whaleback deck – based on the hull design of older whaling boats.
1.A type of open boat that is relatively narrow and pointed at both ends, enabling it to move either forwards or backwards equally well.
2.On modern warships, a relatively light and seaworthy boat used for transport of the ship's crew.
3.A type of vessel designed as a lifeboat or "monomoy" used for recreational and competitive rowing in the San Francisco Bay area and coastal Massachusetts.
A structure on the shore of a harbor or on the bank of a river or canal where ships may dock to load and unload cargo or passengers. Such a structure includes one or more berths (i.e. mooring locations), and may also include piers, warehouses, or other facilities necessary for handling the ships. The term "wharf" is generally synonymous with quay, although the solid foundations of a quay contrast with the closely spaced piles of a wharf. When "quay" and "wharf" are used as synonyms, the term "quay" is more common in everyday speech in the United Kingdom, many Commonwealth countries, and Ireland, while "wharf" is more commonly used in the United States.
A type of boat traditionally used for carrying cargo or passengers on rivers and canals in England, particularly on the River Thames and the Norfolk and Suffolk Broads.
A small single blocktackle, used to raise light loads from a hold.[111]
whip upon whip
Connecting two whips together. This runs more smoothly than using a double block with single block tackle, which would have the equivalent purchase. Can be used for topsail and top-gallanthalliards.[111]
whipping
The binding with twine of the loose end of a rope to prevent it unravelling.[2]
A British flag flown as an ensign by certain British ships. Prior to 1864, ships of the Royal Navy's White Squadron flew it; since the reorganisation of the Royal Navy in 1864, it has been flown by all Royal Navy ships and shore establishments, yachts of members of the Royal Yacht Squadron, and ships of Trinity House escorting the reigning monarch of the United Kingdom.
wide berth
To leave room between two ships moored (berthed) in order to allow space for manoeuvring.
A mechanical device for pulling on a rope (such as a sheet or halyard), usually equipped with a pawl to assist in control. It may be hand-operated or powered.
wind-over-tide
Sea conditions in which a tidal current and a wind are moving in opposite directions, leading to short, heavy seas.
A large iron- or steel-hulled square-rigged sailing ship of the late 19th and early 20th centuries with three, four, or five masts, built mainly between the 1870s and 1900 to carry cargo on long voyages.
A winch mechanism, usually with a horizontal axis, designed to move very heavy loads. Used where mechanical advantage greater than that obtainable by block and tackle was needed (such as raising the anchor on small ships).[111]
windsail
A wide tube or funnel of canvas used to convey a stream of air into the lower compartments of a ship for ventilation.
In the direction that the wind is coming from. Contrast leeward.
wing
An extension on the side of a vessel, e.g. a bridge wing is an extension of the bridge to both sides, intended to allow bridge personnel a full view to aid in the manoeuvring of the ship.
The most junior rate among personnel who work in the engine room of a ship, responsible for cleaning the engine spaces and machinery and assisting the engineers as directed. A wiper is often serving an apprenticeship to become an oiler.
working up
Training on a warship to achieve the best possible effectiveness, usually after commissioning or a refit.[114]
To apply a multilayered protection against chafing and deterioration to a section of line by laying yarns to fill in the cuntlines (worming), wrapping marline or other small stuff around it (serving), and stitching a covering of canvas over all (parcelling).[115] It can be applied to the entire length of a line, such as a shroud, or selectively to specific parts of a line, such as over the spliced ends of a stay, where the chafe on the middle section of the stay precludes complete protection.
1.A Mediterranean sailing ship, usually employed for trading, that is propelled by a combination of lateen sails and oars and characterized by a distinctive hull with a pronounced overhanging bow and stern; early xebecs had two masts and later ones had three.
2.A small, fast warship of the 16th to 19th centuries similar in design to a trading xebec and used almost exclusively in the Mediterranean Sea. This kind of xebec was slightly smaller than a contemporary frigate and mounted slightly fewer guns.
xebec-frigate
A European warship that appeared late in the history of the xebec. It was fully square-rigged but otherwise designed like an ordinary xebec.
The name initially given to a ship during its construction. The yard name may or may not be the same as the officially registered name, which is provided after completion of the vessel.
yard number
The number assigned to a ship built by a particular shipyard. Each shipyard typically numbers the ships that it has built in consecutive order. One use is to identify the ship before a name has been chosen.
The very end of a yard. Often mistaken for the yard itself, which refers to the entire spar. As in to hang "from the yardarm" and the sun being "over the yardarm" (late enough to have a drink).[88]
yar
(of a vessel, especially a sailing vessel) Quick, agile, and easy to steer, hand, and reef.
yarr
Acknowledgement of an order, or agreement. Also aye, aye.
1.A fore-and-aft-rigged sailing vessel with two masts, main and mizzen, the mizzen stepped abaft the rudder post.
2.An un-decked boat, often beach-launched, worked under both oar and sail, and generally clinker-built. Used for fishing, serving ships in anchorages, salvage work, etc. Those from the northern parts of Britain tended to be double-ended.[30]:74
yawl boat
A rowboat on davits at the stern of the boat.
yeoman
A U.S. Navy enlisted rating (YN) responsible for administrative duties.
A type of Scottish sailboat introduced in 1879, used for fishing. A zulu is carvel-built, with the vertical stem of a fifie and the steeply raked stern of a skaffie; two masts rigged with three sails (fore, mizzen, and jib); and a longer deck and shorter keel than previous Scottish fishing boats, allowing greater maneuverability. The term "zulu" came from the Zulu War, which the United Kingdom fought in 1879 at the time the zulu was introduced.
However, "to turn turtle" means putting a turtle on its back by grabbing it by the flipper, and conversely is used to refer to a vessel that has turned upside-down, or has cast off its crew.
