HMCS Lachine
HMCS ''Lachine'' was a of the Royal Canadian Navy that served during the Second World War. Following the war a proposed transfer to the Royal Canadian Mounted Police as ''Starnes'' was cancelled, and the ship was instead sold for conversion to a salvage tug in 1945. The ship was broken up in the United Kingdom in 1955. Design and description The ''Bangor'' class was initially to be a scaled down minesweeper design of the in Royal Navy service.Brown, p. 124Chesneau (1980), p. 61 However, due to the difficulty procuring diesel engines led to the small number of the diesel version being completed. The ships displaced standard and fully loaded. They were long with a beam of and a draught of .Macpherson and Barrie (2002), p. 185 However, the size of the ship led to criticisms of their being too cramped for magnetic or acoustic minesweeping gear. This may have been due to all the additions made during the war with the installation of ASDIC, radar and depth charges. The ...

Lachine, Quebec
Lachine () is a borough (''arrondissement'') within the city of Montreal on the Island of Montreal in southwestern Quebec, Canada. It was an autonomous city until the municipal mergers in 2002. History Lachine, apparently from the French term ''la Chine'' (China), is often said to have been named in 1667, in mockery of its then owner René-Robert Cavelier de La Salle, who explored the interior of North America trying to find a passage to China. When he returned without success, he and his men were derisively named ''les Chinois'' (the Chinese). The name was adopted when the parish of Saints-Anges-de-la-Chine was created in 1676, with the form Lachine appearing with the opening of a post office in 1829. An alternative etymology attributes the name to the famous French explorer Samuel de Champlain, who also hoped to find a passage from the Saint Lawrence River to China. According to this version, in 1618 Champlain proposed that a customs house would tax the trade goods from China ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank "corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in sev ...

Western Local Escort Force
Western Local Escort Force (WLEF) referred to the organization of anti-submarine escorts for World War II trade convoys from North American port cities to the Western Ocean Meeting Point (WOMP or WESTOMP) near Newfoundland where ships of the Mid-Ocean Escort Force (MOEF) assumed responsibility for safely delivering the convoys to the British Isles.Morison (1975) p. 319 Background On the basis of experience during World War I, the Admiralty instituted trade convoys in United Kingdom coastal waters from September 1939. Convoys gradually extended westward until HX 129 left Halifax, Nova Scotia on 27 May 1941 as the first convoy to receive escort for the entire trip from Canada. The American Neutrality Zone offered some protection in North American coastal waters until United States declaration of war in December 1941. Organization The Royal Canadian Navy organized the Halifax-based Western Local Escort Force in February 1942 as German U-boats began patrolling North American coast ...

Sydney, Nova Scotia
Sydney is a former city and urban community on the east coast of Cape Breton Island in Nova Scotia, Canada within the Cape Breton Regional Municipality. Sydney was founded in 1785 by the British, was incorporated as a city in 1904, and dissolved on 1 August 1995, when it was amalgamated into the regional municipality. Sydney served as the Cape Breton Island's colonial capital, until 1820, when the colony merged with Nova Scotia and the capital moved to Halifax. A rapid population expansion occurred just after the turn of the 20th century, when Sydney became home to one of North America's main steel mills. During both the First and Second World Wars, it was a major staging area for England-bound convoys. The post-war period witnessed a major decline in the number of people employed at the Dominion Steel and Coal Corporation steel mill, and the Nova Scotia and Canadian governments had to nationalize it in 1967 to save the region's biggest employer, forming the new crown corpora ...

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any pennants ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

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. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
