HMCS James Bay (hull number MCB 152) was a Bay-class minesweeper that was constructed for the Royal Canadian Navy during the Cold War. Entering service in 1954, the ship served on the West Coast of Canada until 1964 when James Bay was decommissioned. The minesweeper was sold in 1966 for use as an offshore oil exploration vessel.

Design and description

edit

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

edit

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]
