Merchant navyA merchant navy or merchant marine is the fleet of merchant vessels that are registered in a specific country. On merchant vessels, seafarers of various ranks and sometimes members of are required by the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) to carry Merchant Mariner's Documents. King George V bestowed the title of the "Merchant Navy" on the British merchant shipping fleets following their service in the First World War; since then a number of other nations have also adopted use of that title or the similar "Merchant Marine".
Park shipPark ships were merchant steamships constructed for Canada’s Merchant Navy during the Second World War. Park ships and Fort ships (built in Canada for operation by the British) were the Canadian equivalent of the American Liberty ships. All three shared a similar design by J.L. Thompson and Sons of Sunderland, England. Fort ships had a triple expansion steam engine and a single screw propeller. Fort ships were ships transferred to the British government and the Park ships were those employed by the Canadian government, both had the similar design.
Cargo shipA cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's seas and oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped.
Fort shipThe Fort ships were a class of 198 cargo ships built in Canada during World War II for use by the United Kingdom. They all had names prefixed with "Fort" when built. The ships were in service between 1942 and 1985, with two still listed on shipping registers until 1992. A total of 53 were lost during the war due to accidents or enemy action. One of these, , was destroyed in 1944 by the detonation of 1,400 tons of explosive on board her. This event, known as the Bombay Explosion, killed over 800 people and sank thirteen ships.
Liberty shipLiberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost.
Victory shipThe Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines, giving higher speed to allow participation in high-speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built in between 1944 and 1946.
