HMCS Wolf
HMCS ''Wolf'' was an armed yacht of the Royal Canadian Navy during World War II that saw service on the British Columbia Coast of Canada. Constructed in 1915 as the yacht ''Wenowah'', with the US entry into World War I, the vessel was taken into United States Navy service as USS ''Wenonah'' (SP-165) as a patrol ship. The vessel escorted convoys between the United States and Europe and between Gibraltar and Bizerte, Tunis and Genoa, Italy. After the war, ''Wenonah'' was loaned to the United States Coast and Geodetic Survey for three and a half years before being sold to private interests in 1928. In private ownership, the vessel was renamed at least twice, including ''Stranger'' and ''Blue Water''. With the onset of World War II, the Royal Canadian Navy sought vessels capable of patrol duties. However, a lack of Canadian ships led them to acquiring vessels from their southern neighbour. ''Blue Water'' was acquired in 1940 for service on the British Columbia coast and used a patrol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Lawley & Sons
George Lawley & Son was a shipbuilding firm operating in Massachusetts from 1866 to 1945. It began in Scituate, then moved to Boston. After founder George Lawley (1823–1915) retired in 1890, his son, grandson and great-grandson upheld the business, which continued until 1945. Of the hundreds of ships built by the Lawleys, highlights include the yachts ''Puritan'' and ''Mayflower'', respective winners of the 1885 and 1886 America's Cup. Brief history Founder George Lawley (1823–1915) was born to a "family of boatbuilders in Limehouse (London), England." He "began his career as an apprentice to Thomas and William Forrest while in England." In 1852 Lawley "moved his family to Massachusetts." He "found his first job in America with the East Boston ship designer, Donald McKay." Lawley worked for McKay from 1852 until 1866. Scituate, 1866–1874 In 1866, "Lawley and fellow cKayworker William Maybury opened a shipyard in Scituate ... for the construction of pleasure boats." Wh ...

Submarine Chaser
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German submarines in World War I, and Japanese and German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class was built for World War II. Also in World War II, larger PC-461-class submarine chasers used the PC hull classification symbol (for Patrol, Coastal).Gardiner and Chesneau, pp. 71, 152-154 Class relationships: * 438 (98t, wooden hull) * 343 (450t, steel hull) * 68 (850t, steel hull) ** used in sim ...

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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull Number
Hull number is a serial identification number given to a boat or ship. For the military, a lower number implies an older vessel. For civilian use, the HIN is used to trace the boat's history. The precise usage varies by country and type. United States usage Civilian use For civilian craft manufactured in the United States, the hull number is given to the vessel when it is built and forms part of the hull identification number, which uniquely identifies the vessel and must be permanently affixed to the hull in at least two places. A Hull Identification Number (HIN) is a unique set of 12 characters, similar to the Vehicle Identification Number which is found on automobiles. In 1972, The United States Coast Guard was asked to create a standardized format for HINs to allow for better tracking of accidents and history of boats. This HIN format is as follows: The first three characters consist of the Manufacturers Index Code (MIC) and should only be letters. The following five character ...

3"/50 Caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships. Low-angle 3"/50 caliber guns (Marks 3, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Triple Expansion
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a s ...

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. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and a ... [...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 In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...
