Wyoming was an American wooden six-masted schooner built and completed in 1909 by the Percy & Small Shipyard in Bath, Maine.[1] With a length of 450 ft (140 m) from jib-boom tip to spanker boom tip, Wyoming was the largest known wooden ship ever built.[4]

Because of its extreme length and wood construction, Wyoming tended to flex in heavy seas, which would cause the long planks to twist and buckle, thereby allowing sea water to intrude into the hold. Wyoming had to use pumps to keep its hold relatively free of water. In March 1924, it foundered in heavy seas and sank with the loss of all hands.
Wyoming was designed by Bant Hanson with Miles M. Merry, the master builder for the North American Atlantic coastal trade, for the company Percy & Small and the intended cargo being coal.[5]
Wyoming was 450 ft (140 m) overall, 350 ft (110 m) on deck, and 329.5 feet (100.4 m) between perpendiculars. It was 50 ft 1 in (15.27 m) wide, and had a draft of 30 ft 5 in (9.27 m). Its gross register tonnage (GRT) was 3730, equivalent to an internal volume of 373,000 cubic feet (10,600 m3). Its net register tonnage (NRT) was 3036, representing a cargo capacity of 303,600 cubic feet (8,600 m3) after subtracting the volume consumed by the helm and crew quarters and other areas not suitable for cargo. It had a deadweight tonnage (DWT) of 6,004 long tons, that is, the weight of the ship fully loaded, including the crew, cargo (6,000 tons), fuel, water and stores, less the weight of the ship when totally empty (4,000 tons). It could carry 6,000 long tons of coal. Wyoming was built of yellow pine with 6" planking and there were 90 diagonal iron cross-bracings on each side.
Wyoming was equipped with a Hyde anchor windlass and a donkey steam engine to raise and lower sails, haul lines and perform other tasks; the steam engine was not used to power the ship, but permitted it to be sailed with a smaller crew of only 11 hands. It was named for the state of Wyoming because Wyoming Governor Bryant Butler Brooks (1907–1921) was one of the investors in the ship, which cost $175,000 in 1909 dollars ( approx $5,849,000 US Dollars 2023 ). Another Percy & Small-built schooner, the five-masted Governor Brooks, was named after Brooks.
