HMS Cachalot (S06)
HMS ''Cachalot'' (S06) was a British Porpoise class submarine, ''Porpoise''-class submarine. Her keel was laid down on 1 August 1955 by Scotts Shipbuilding and Engineering Company at Greenock. She was launched on 11 December 1957, and ship commissioning, commissioned on 1 September 1959. Design The ''Porpoise'' class was the first class of operational submarines built for the Royal Navy after the end of the Second World War, and were designed to take advantage of experience gained by studying German Type XXI U-boats and British wartime experiments with the submarine , which was modified by streamlining and fitting a bigger battery. The ''Porpoise''-class submarines were length overall, long overall and length between perpendiculars, between perpendiculars, with a Beam (nautical), beam of and a Draft (ship), draught of . Displacement (ship), Displacement was standard and full load surfaced and submerged. Propulsion machinery consisted of two Admiralty Standard Range die ...

Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland.

Draft (ship)
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 aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blyth, Northumberland
Blyth () is a town and civil parish in southeast Northumberland, England. It lies on the coast, to the south of the River Blyth and is approximately northeast of Newcastle upon Tyne. It has a population of about 37,000, as of 2011. The port of Blyth dates from the 12th century, but the development of the modern town only began in the first quarter of the 18th century. The main industries which helped the town prosper were coal mining and shipbuilding, with the salt trade, fishing and the railways also playing an important role. These industries have largely vanished, but the port still thrives, receiving paper and pulp from Scandinavia for the newspaper industries of England and Scotland. The town was seriously affected when its principal industries went into decline, and it has undergone much regeneration since the early 1990s. The Keel Row Shopping Centre, opened in 1991, brought major high street retailers to Blyth, and helped to revitalise the town centre. The market place ...

Spithead
Spithead is an area of the Solent and a roadstead off Gilkicker Point in Hampshire, England. It is protected from all winds except those from the southeast. It receives its name from the Spit, a sandbank stretching south from the Hampshire shore for . Spithead is long by about in average breadth. Spithead has been strongly defended since 1864 by four Solent Forts, which complement the Fortifications of Portsmouth. The Fleet Review is a British tradition that usually takes place at Spithead, where the monarch reviews the massed Royal Navy. The Spithead mutiny occurred in 1797 in the Royal Navy fleet at anchor at Spithead. It is also the location where sank in 1782 with the loss of more than 800 lives.

Fleet Review
A fleet review or naval review is an event where a gathering of ships from a particular navy is paraded and reviewed by an incumbent head of state and/or other official civilian and military dignitaries. A number of national navies continue to hold fleet reviews. Fleet reviews may also include participants and warships from multiple navies. Commonwealth realms Fleet reviews in the Commonwealth realms are typically observed by the reigning monarch or their representative, a practice allegedly dating back to the 15th century. Such an event is not held at regular intervals and originally only occurred when the fleet was mobilised for war or for a show of strength to discourage potential enemies, or during periods of commemorations. Since the 19th century, they have often been held for the coronation or for special royal jubilees and increasingly included delegates from other national navies. Traditionally, a fleet review will have participating ships dressed in flags and pennants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British 21 Inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which used smaller 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US (destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at . Mark IV From 1912, used by destro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

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 ...

Scotts Shipbuilding And Engineering Company
Scotts Shipbuilding and Engineering Company Limited, often referred to simply as Scotts, was a Scottish shipbuilding company based in Greenock on the River Clyde. In its time in Greenock, Scotts built over 1,250 ships. History John Scott founded the company in 1711. He built herring busses and small craft. He was succeeded by his son William Scott (1722-1769) and another son. In 1765 they built their first square-rigged vessel. William's son John (1752-1837) expanded the shipyard to a major shipbuilding company. The Scott family took over the Greenock Foundry in 1790. In 1791, Scott & Co. built , of 600-ton (bm), for the Newfoundland trade. She and , built in 1794, were the largest ships built in Scotland in their years. They marked the beginning of increased activity by Scott & Co., particularly with respect to large, ocean-going ships. C. G. Scott started building at Cartsdyke Dockyard in 1850, as Scott & Company.

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...
