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.
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). They had a complement of 38 officers and ratings.
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). The ships were armed with one 40 mm Bofors gun and were equipped with minesweeping gear.
