HMS Mounsey (1915)
HMS ''Mounsey'' was a Yarrow M-class destroyer of the British Royal Navy. Built by the Scottish shipbuilder Yarrow Shipbuilders, Yarrow in 1914–1915, ''Mounsey'' served in the Grand Fleet during the First World War, and took part in the Battle of Jutland. The following year she saw combat against German submarines, and in 1918 she helped rescue crew and passengers aboard the damaged troopship HMS Otranto, ''Otranto''. She was sold for scrap in 1921. Design and construction The M-class destroyers were designed to meet a requirement for faster destroyers than the previous Laforey-class destroyer (1913), ''Laforey''-class , in order to match reported German ships. They hoped for a speed of , but otherwise, the requirements were similar to those that gave rise to the ''Laforey''s. As part of its 1913–1914 shipbuilding programme, the Admiralty (United Kingdom), Admiralty ordered six ships to the standard Admiralty M-class destroyer, Admiralty design, together with seven builder' ...

United Kingdom Of Great Britain And Ireland
The United Kingdom of Great Britain and Ireland was a sovereign state in the British Isles that existed between 1801 and 1922, when it included all of Ireland. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927. The United Kingdom, having financed the European coalition that defeated France during the Napoleonic Wars, developed a large Royal Navy that enabled the British Empire to become the foremost world power for the next century. For nearly a century from the final defeat of Napoleon following the Battle of Waterloo to the outbreak of World War I, Britain was almost continuously at peace with Great Powers. The most notable exception was the Crimean War with the Russian Empire, in which actual hostilities were relatively ... [...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 ' ...

River Clyde
The River Clyde ( gd, Abhainn Chluaidh, , sco, Clyde Watter, or ) is a river that flows into the Firth of Clyde in Scotland. It is the ninth-longest river in the United Kingdom, and the third-longest in Scotland. It runs through the major city of Glasgow. Historically, it was important to the British Empire because of its role in shipbuilding and trade. To the Romans, it was , and in the early medieval Cumbric language, it was known as or . It was central to the Kingdom of Strathclyde (). Etymology The exact etymology of the river's name is unclear, though it is known that the name is ancient: It was called or by the Britons and by the Romans. It is therefore likely that the name comes from a Celtic language—most likely Old British. But there is more than one old Celtic word that the river's name could plausibly derive from. One possible root is the Common Brittonic , meaning 'loud' or 'loudly'. More likely, the river was named after a local Celtic goddess, '' Clōta ...

North Channel (Great Britain And Ireland)
The North Channel (known in Irish and Scottish Gaelic as , in Scots as the ) is the strait between north-eastern Northern Ireland and south-western Scotland. It begins north of the Isle of Man, where the Irish Sea ends, and runs north-west into the Atlantic Ocean. Geography The North Channel connects the Irish Sea with the Atlantic Ocean and is part of the marine area officially classified as the " Inner Seas off the West Coast of Scotland" by the International Hydrographic Organization (IHO). The Straits of Moyle ( in Irish and Scottish Gaelic) or Sea of Moyle is the name given to the narrowest expanse of sea in the North Channel between north-eastern Northern Ireland (County Antrim) and south-western highlands of Scotland ( Mull of Kintyre). The distance between the two shores is approximately at its closest point, and thus it is possible to see across in clear weather conditions. The straits gave their name to Moyle District Council, a local government area in Northe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lough Swilly
Lough Swilly () in Ireland is a glacial fjord or sea inlet lying between the western side of the Inishowen Peninsula and the Fanad Peninsula, in County Donegal. Along with Carlingford Lough and Killary Harbour it is one of three glacial fjords in Ireland. Geography and ecology Located on the Fanad Peninsula, in County Donegal, the northern extremities of the lough are marked by Fanad Head with its lighthouse and Dunaff Head. Towns situated on the lough include Buncrana on Inishowen and Rathmullan on the western side. At the southern end of the lough lies Letterkenny. In the south of the lough a number of islands (Burt, Inch, Coney, Big Isle) were poldered and the land reclaimed during the 19th century for agriculture and the Londonderry and Lough Swilly Railway constructed embankments on the line from Derry to Letterkenny. These reclaimed lands are now wetlands associated with wildlife conservation and birdwatching, and support over 4,000 whooper swans and thousands of Greenla ...

11th Destroyer Flotilla
The British 11th Destroyer Flotilla, or Eleventh Destroyer Flotilla, was a naval formation of the Royal Navy from August 1915 to September 1945. History World War One The 11th Destroyer Flotilla was formed in August 1915 and was assigned to the Grand Fleet. It took part in the Battle of Jutland, and then remained with Grand Fleet until November 1918. Initially the formation consisted of sixteen M class destroyers, some of which were replaced by R class destroyers. For most of 1918 the flotilla was mainly using V and W-class destroyers. The flotilla was disbanded in March 1919, but was briefly reformed during the Interwar period. Interwar period The flotilla was briefly reformed from 1 July 1935 to 30 August 1935 under the command of Captain Ernest R. Archer (later Vice-Admiral). Second World War The flotilla was reformed in 1939 and was attached to the Plymouth Command until 1940 when its ships were dispersed among various escort groups. It was re-established again in Augu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Trials
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship 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 (ship), 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 widel ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Mounsey (Royal Navy Officer)
William Mounsey CB (1766 – 25 September 1830) was a British officer of the Royal Navy. He served during the American Revolutionary, the French Revolutionary and the Napoleonic Wars, rising to the rank of Captain. Family and early life Mounsey was born in 1766, as the fifth son of George Mounsey, of Carlisle. He joined the navy on 23 February 1780, at the age of 13, becoming a midshipman aboard , under Captain Sir Digby Dent, who would become Mounsey's patron. The ''Royal Oak'' was sent to the North American Station in May to reinforce Vice-admiral Mariot Arbuthnot's fleet. During the voyage Mounsey took part in the capture of a French East Indiaman. They reached their destination on 13 July, after which Arbuthnot raised his flag aboard the ''Royal Oak'', whilst Dent and Mounsey moved aboard . The ''Raisonnable'' then returned home with despatches, but the ship was so badly damaged by a gale whilst crossing the Atlantic, that she was paid off on her arrival for large-scale r ...

QF 2-pounder Naval Gun
The 2-pounder gun, officially the QF 2-pounder ( QF denoting "quick firing") and universally known as the pom-pom, was a British autocannon, used as an anti-aircraft gun by the Royal Navy.British military of the period traditionally denoted smaller guns in terms of the approximate weight of the standard projectile, rather than by its bore diameter, which in this case was 40 mm. References to 40-mm anti-aircraft guns invariably mean the Bofors gun, while references to 2-pounder anti-aircraft guns mean this gun. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired , projectiles. Predecessors - Boer War and the Great War QF 1 pounder The first gun to be called a pom-pom was the 37 mm Nordenfelt-Maxim or "QF 1-pounder" introduced during the Second Boer War, the smallest artillery piece of that war.

QF 4 Inch Naval Gun Mk IV, XII, XXII
The QF 4-inch gun Mk IVMk IV = Mark 4. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. This was the fourth model of 4-inch QF naval gun. Variants Mk XII = Mark 12, Mk XXII = Mark 22. was the main gun on most Royal Navy and British Empire destroyers in World War I. It was introduced in 1911 as a faster-loading light gun successor to the BL 4 inch Mk VIII gun. Of the 1,141 produced, 939 were still available in 1939.Campbell, ''Naval Weapons of WWII'', p.59. Mk XII and Mk XXII variants armed many British interwar and World War II submarines. Mk IV gun Mk IV armed many British destroyers and some cruisers in World War I. It was used to arm merchant ships in World War II. The guns armed the following warships : * ''Forward''-class scout cruisers as re-gunned in 1911 * ''Sentinel''-class scout cruisers as re-gunned 1911-1912 * ''Pathfinder''-class scout cruisers as re-gunned 1911-1912 * ''Adventure''-class scout cruisers as re-gunned ...
