Hull classification symbol (Canada)

Hull classification symbol (Canada)

The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's hull classification symbol system. The Royal Navy and some European and Commonwealth navies use a somewhat analogous system of pennant numbers.

Bay-class minesweeper

Bay-class minesweeper

The Bay-class minesweepers, also known as the Gaspé-class minesweepers, were a class of minesweepers operated by the Royal Canadian Navy (RCN) and Canadian Forces (CF) during the Cold War. Their design was similar to the British Ton-class minesweepers.

Minesweeper

Minesweeper

A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping.

Royal Canadian Navy

Royal Canadian Navy

The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff.

Cold War

Cold War

The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term cold war is used because there was no large-scale fighting directly between the two superpowers, but they each supported opposing sides in major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race.

British Columbia Coast

British Columbia Coast

The British Columbia Coast, popularly referred to as the BC Coast or simply the Coast, is a geographic region of the Canadian province of British Columbia. As the entire western continental coastline of Canada along the Pacific Ocean is in B.C., it is synonymous with being the West Coast of Canada.

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]

Ton-class minesweeper

Ton-class minesweeper

The Ton class were coastal minesweepers built in the 1950s for the Royal Navy, but also used by other navies such as the South African Navy and the Royal Australian Navy. They were intended to meet the threat of seabed mines laid in shallow coastal waters, rivers, ports and harbours, a task for which the existing ocean-going minesweepers of the Algerine-class were not suited.

Displacement (ship)

Displacement (ship)

The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used.

Length overall

Length overall

Length overall is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth.

Beam (nautical)

Beam (nautical)

The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water.

Draft (hull)

Draft (hull)

The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water.

General Motors

General Motors

The General Motors Company (GM) is an American multinational automotive manufacturing company headquartered in Detroit, Michigan, United States. It is the largest automaker in the United States and was the largest in the world for 77 years before losing the top spot to Toyota in 2008.

Diesel engine

Diesel engine

The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine. This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine or a gas engine.

Knot (unit)

Knot (unit)

The knot is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h. The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non-SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour.

Nautical mile

Nautical mile

A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute of latitude. Today the international nautical mile is defined as exactly 1,852 metres. The derived unit of speed is the knot, one nautical mile per hour.

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]

Keel

Keel

The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event.
