Endeavour had a displacement of 1,560 long tons (1,585 t) at full load with a length overall of 236 feet 0 inches (71.9 m), a beam of 38 feet 6 inches (11.7 m) and a draught of 13 feet 0 inches (4.0 m). Endeavour's hull was stiffened for work in areas with ice.[2]
The ship was propelled by two shafts driven by a diesel-electric engine creating 2,960 shaft horsepower (2,207 kW). The machinery space was insulated to reduce noise. This gave the vessel a maximum speed of 16 knots (30 km/h) and a range of 10,000 nautical miles (19,000 km) at 12 knots (22 km/h). Endeavour could turn 21⁄2 times its length. The ship had a 48-by-31-foot (14.6 m × 9.4 m) helicopter deck. The ship was fitted with two 9-ton Austin-Weston telescopic cranes. Two oceanographical winches, each holding 5,000 fathoms (9,100 m) of wire, two bathythermograph winches and one deep-sea coring winch were also fitted. The vessel had a complement of 50, which included 10 officers, 13 scientists and two aircrew.[2]
Endeavour was ordered from Yarrows Ltd. and constructed at their shipyard in Esquimalt, British Columbia and given the yard number 250.[3][4] Endeavour's keel was laid down on 4 September 1963 and the ship was launched on 4 September 1964.[4] The vessel was commissioned into the Royal Canadian Navy on 9 March 1965 and given the hull number AGOR 171.[2] Endeavour was deployed on the West Coast of Canada researching anti-submarine warfare from the time the ship entered service until 1999. The vessel replaced the old Bangor-class minesweeper Oshawa. In 1999, Endeavour was transferred to the East Coast to replace Quest temporarily, while Quest was undergoing modernisation. In 2000, Endeavour was discarded.[3]
