Design and description

The Bay class were designed and ordered as replacements for the Second World War-era minesweepers that the Royal Canadian Navy operated at the time. Similar to the Ton-class minesweeper, they were constructed of wood planking and aluminum framing.^[2][3]

Displacing 390 long tons (400 t) standard at 412 long tons (419 t) at deep load, the minesweepers were 152 ft (46 m) long with a beam of 28 ft (8.5 m) and a draught of 8 ft (2.4 m).^[2][3] They had a complement of 38 officers and ratings.^{[2][note 1]}

The Bay-class minesweepers were powered by two GM 12-cylinder diesel engines driving two shafts creating 2,400 brake horsepower (1,800 kW). This gave the ships a maximum speed of 16 knots (30 km/h; 18 mph) and a range of 3,290 nautical miles (6,090 km; 3,790 mi) at 12 knots (22 km/h; 14 mph).^[3][4] The ships were armed with one 40 mm Bofors gun and were equipped with minesweeping gear.^[2][3]

Operational history

The ship's keel was laid down on 16 August 1951 by Yarrows Ltd. in Esquimalt, British Columbia. Initially named Chantry, the vessel was renamed for a bay located between Ontario and Quebec with islands that are part of Nunavut within.^[5] James Bay was launched on 12 March 1953. The ship was commissioned on 3 May 1954.^[6]

The Second Canadian Minesweeping Squadron was formed in May 1954 at Esquimalt with Comox and James Bay as the first two vessels of the unit.^[7] Serving on the West Coast of Canada, in November 1955, the Second Canadian Minesweeping Squadron was among the Canadian units that took part a large naval exercise off the coast of California.^[8] The Second Minesweeping Squadron, of which James Bay was a member made a port visit at Stockton, California in June 1960.^[9] The vessel was paid off on 28 February 1964. James Bay was sold to commercial interests in 1966 for use in offshore oil exploration.^[5][6]
