HMS TB 12 (1907)
HMS ''TB 12'' (originally named HMS ''Moth'') was a ''Cricket''-class coastal destroyer or torpedo-boat of the British Royal Navy. ''TB 12'' was built by the shipbuilder Yarrow from 1905 to 1907. She was used for local patrol duties in the First World War and was sunk by a German mine in the North Sea on 10 June 1915. Design The ''Cricket''-class was intended as a smaller and cheaper supplement to the large, fast but expensive ''Tribal''-class, particularly in coastal waters such as the English Channel. An initial order for twelve ships was placed by the Admiralty in May 1905 as part of the 1905–1906 shipbuilding programme, with five ships each ordered from Thornycroft and J. Samuel White and two from Yarrow . Yarrow's ships (the different shipbuilders built to their own design, although standardised machinery and armament was fitted) were long overall and between perpendiculars, with a beam of and a draught of . The ships had turtleback forecastles and two funnels. Two o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 limited. How ...

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 ...

Torpedo Boats Of The Royal Navy
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though some ...

Fishing Smack
A smack was a traditional fishing boat used off the coast of Britain and the Atlantic coast of America for most of the 19th century and, in small numbers, up to the Second World War. Many larger smacks were originally cutter-rigged sailing boats until about 1865, when smacks had become so large that cutter main booms were unhandy. The smaller smacks retain the gaff cutter rig. The larger smacks were lengthened and re-rigged and new ketch-rigged smacks were built, but boats varied from port to port. Some boats had a topsail on the mizzen mast, while others had a bowsprit carrying a jib. Large numbers of smacks operated in fleets from ports in the UK such as Brixham, Grimsby and Lowestoft as well as at locations along the Thames Estuary. In England the sails were white cotton until a proofing coat was applied, usually after the sail was a few years old. This gave the sails its distinctive red ochre colour, which made them a picturesque sight in large numbers. Smacks were oft ...

Dartmouth Naval College
Britannia Royal Naval College (BRNC), commonly known as Dartmouth, is the naval academy of the United Kingdom and the initial officer training establishment of the Royal Navy. It is located on a hill overlooking the port of Dartmouth, Devon, England. Royal Naval officer training has taken place in Dartmouth since 1863. The buildings of the current campus were completed in 1905. Earlier students lived in two wooden hulk (ship type), hulks moored in the River Dart. Since 1998, BRNC has been the sole centre for Royal Naval officer training. History The training of naval officers at Dartmouth dates from 1863, when the wooden hulk was moved from Portland Harbour, Portland and moored in the River Dart to serve as a base. In 1864, after an influx of new recruits, ''Britannia'' was supplemented by . Prior to this, a Royal Naval Academy (later Royal Naval College) had operated for more than a century from 1733 to 1837 at Portsmouth, a major naval installation. The original ''Britannia' ...

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 life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hundredweight
The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and US customary unit of weight or mass. Its value differs between the US and British imperial systems. The two values are distinguished in American English as the "short" and "long" hundredweight and in British English as the "cental" and the "imperial hundredweight". * The short hundredweight or cental of is used in the United States. * The long or imperial hundredweight of 8 stone or is defined in the imperial system. Under both conventions, there are 20 hundredweight in a ton, producing a " short ton" of 2,000 pounds and a " long ton" of 2,240 pounds. History The hundredweight has had many values. In England in around 1300, different "hundreds" (''centum'' in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 lb. The United States and Canada came to use the ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...
