HMS Inconstant (1868)
HMS ''Inconstant'' was an unarmored, iron-hulled, screw frigate built for the Royal Navy in the late 1860s. Upon completion in 1869, she was the fastest warship in the world and was assigned to the Channel Squadron. Two years later the ship was transferred to the Detached Squadron for a brief time before she was paid off into reserve in 1872. ''Inconstant'' was recommissioned in 1880 for service with the Flying Squadron that circumnavigated the world in 1880–82. On the return voyage, the ship was diverted to Egypt during the Anglo-Egyptian War of 1882 and played a minor role supporting operations ashore. She was reduced to reserve again after her return and was served as an accommodation ship in 1897. ''Inconstant'' was hulked in 1904 and became a training ship in 1906. She continued in that role, under a variety of names, until she was sold for scrap in 1955 and subsequently broken up, the second-to-last surviving Pembroke-built warship in existence.

Pembroke Dockyard
Pembroke Dockyard, originally called Pater Yard, is a former Royal Navy Dockyard in Pembroke Dock, Pembrokeshire, Wales. History It was founded in 1814, although not formally authorized until the Prince Regent signed the necessary Order in Council on 31 October 1815, and was known as ''Pater Yard'' until 1817. The Mayor of Pembroke had requested the change "in deference to the town of Pembroke some distant". The site selected for the dockyard was greenfield land and the closest accommodations were in Pembroke. Office space was provided by the old frigate after she was beached. The Royal Marine garrison was housed in the hulked 74-gun ship, , after she was run aground in 1832. Many of the workmen commuted by boat from nearby communities until Pembroke Dock town was built up. In 1860 the dockyard's policing was transferred to the new No. 4 Division of the Metropolitan Police, which remained in that role until the 1920s. After the end of the First World War, the dockyard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Decommissioning
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 correct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonnage
Tonnage is a measure of the cargo-carrying capacity of a ship, and is commonly used to assess fees on commercial shipping. The term derives from the taxation paid on ''tuns'' or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual weight of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a "tun" of wine typically weighed that much. Tonnage measurements Tonnage measurements are governed by an IMO Convention (International Convention on Tonnage Measurement of Ships, 1969 (London-Rules)), which initially applied to all ships built after July 1982, and to older ships from July 1994.

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 ...

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 aft ... [...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 ...

USS Wampanoag (1864)
The first USS ''Wampanoag'' was a screw frigate in the United States Navy built during the American Civil War. Development and design Commerce raiding by CSS ''Alabama'' and CSS ''Florida'', both built in English yards, reached a point in 1863 where continued peaceful relations between the United States and Great Britain were seriously jeopardized. As a result, Congress responded by authorizing construction of a new class of screw frigates as part of the naval procurement bill of that year. These vessels, designed to be the fastest in the world, were intended for use in hit-and-run operations against British ports and commerce in the event of war. ''Wampanoag'' was the lead ship of this class, which also included the ''Madawaska''. ''Wampanoag'' contained numerous design features unprecedented in American naval construction. Her hull — designed by clipper ship architect Benjamin Franklin Delano — was unusually long and tapered relative to the vessel's beam. Her ma ...

Edward James Reed
Sir Edward James Reed, KCB, FRS (20 September 1830 – 30 November 1906) was a British naval architect, author, politician, and railroad magnate. He was the Chief Constructor of the Royal Navy from 1863 until 1870. He was a Liberal politician who sat in the House of Commons from 1874 to 1906. Early life Edward Reed was born in Sheerness, Kent and was the son of John and Elizabeth Reed. He was a naval apprentice at Sheerness and subsequently entered the School of Mathematics and Naval Construction at Portsmouth. In 1851 he married Rosetta, the sister of Nathaniel Barnaby. Barnaby was at that time a fellow student; he would subsequently succeed Reed as Chief Constructor. In 1852 he entered employment at Sheerness Dockyard, but resigned after a disagreement with the management. He then worked in journalism, including editing the '' Mechanics' Magazine''. In 1860, Reed was appointed secretary of the newly formed Institute of Naval Architects. Naval architect In 1863, at the ear ...

Chief Constructor
The Director of Naval Construction (DNC) also known as the Department of the Director of Naval Construction and Directorate of Naval Construction and originally known as the Chief Constructor of the Navy was a senior principal civil officer responsible to the Board of Admiralty for the design and construction of the warships of the Royal Navy. From 1883 onwards he was also head of the Royal Corps of Naval Constructors, the naval architects who staffed his department from 1860 to 1966. The (D.N.C.'s) modern equivalent is Director Ships in the Defence Equipment and Support organisation of the Ministry of Defence. History The post evolved from the office of the ''Assistant Surveyor of the Navy'' (1832-1859) In 1860 the ''Assistant Surveyor'' was renamed ''Chief Constructor'' the post lasted until 1875 when it was renamed to the ''Director of Naval Construction''. The chief constructor was originally head of the Royal Corps of Naval Constructors and members of the corps were responsi ...

Pembroke Dock
Pembroke Dock ( cy, Doc Penfro) is a town and a community in Pembrokeshire, South West Wales, northwest of Pembroke on the banks of the River Cleddau. Originally Paterchurch, a small fishing village, Pembroke Dock town expanded rapidly following the construction of the Royal Navy Dockyard in 1814. The Cleddau Bridge links Pembroke Dock with Neyland. After Haverfordwest and Milford Haven, Pembroke Dock is the third-largest town in Pembrokeshire being more populous than neighbouring Pembroke. History The natural harbour (now the Milford Haven Waterway) offering shelter from the prevailing south-westerly winds, has probably been used for many thousands of years. From maps, the first evidence of settlement is the name of the Carr Rocks at the entrance, derived from the Norse-language ''Skare'' for rock. From 790 until the Norman Invasion (1066) the estuary was used by the Vikings. During one visit, either in 854 or in 878, maybe on his way to the Battle of Cynuit, the Viking c ...

Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for undergraduate oceanography and biology students, marine science and physical science for high school students, to character building for at-risk youths.

Anglo-Egyptian War
The British conquest of Egypt (1882), also known as Anglo-Egyptian War (), occurred in 1882 between Egyptian and Sudanese forces under Ahmed ‘Urabi and the United Kingdom. It ended a nationalist uprising against the Khedive Tewfik Pasha. It established firm British influence over Egypt at the expense of the Egyptians, the French, and the Ottoman Empire, whose already weak authority became nominal. Background In 1881, an Egyptian army officer, Ahmed ‘Urabi (then known in English as Arabi Pasha), mutinied and initiated a coup against Tewfik Pasha, the Khedive of Egypt and Sudan, because of grievances over disparities in pay between Egyptians and Europeans, as well as other concerns. In January 1882 the British and French governments sent a "Joint Note" to the Egyptian government, declaring their recognition of the Khedive's authority. On 20 May, British and French warships arrived off the coast of Alexandria. On 11 June, an anti-Christian riot occurred in Alexandria that k ...
