HMS Ouse (1905)
HMS ''Ouse'' was a Laird type River-class destroyer ordered by the Royal Navy under the 1903 – 1904 Naval Estimates. Named after the , she was the first ship to carry this name in the Royal Navy. Design and construction ''Ouse'' was one of three River-class destroyers ordered from Cammel Laird as part of the 1903–04 construction programme, with 16 River-class ships ordered in total under that programme. The destroyers ordered from Lairds under the 1903–04 programme were repeats of those built by Lairds under the 1901–02 programme and the 1902–03 programme. ''Ouse'' was long overall (o/a) and between perpendiculars (pp), with a beam of and a draught of . Displacement was light and full load. ''Ouse'' was powered by two Vertical Triple-Expansion steam engines, rated at to meet the contract speed of . Two funnels were fitted. The ship had a crew of 70 officers and other ranks. As built, ''Ouse''s armament was the same as the turtleback destroyers that preceded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River-class Destroyer
The River-class destroyer (re-designated in 1913 as the E class) was a class of torpedo boat destroyer built for the Royal Navy at the turn of the 20th century, and which saw extensive service in World War I. The class introduced new features to destroyer design, placing a greater emphasis on seakeeping and endurance and less on a high maximum speed in good weather. All the ships were named after British and Irish rivers, and as such were the first Royal Navy destroyer class to be named systematically. Genesis The concept for the River class began in December 1900, with a request from John de Robeck, then the senior destroyer officer in the Mediterranean Fleet, for a new class of destroyer with a longer range than the existing "30-knotter" B, C and, D classes and "27-knotter" A-class types. Robeck's specification called for a range of at a sustained speed of ; the "30-knotter" could only make at its cruising speed of . Robeck also called for various modifications to des ...

HMS Gala (1905)
HMS ''Gala'' was a Yarrow type ordered by the Royal Navy under the 1903 – 1904 Naval Estimates. Named after the Gala Waters in the Scottish Borders area south of Edinburgh, she was the first Royal Navy ship to carry this name. She was launched on 7 January and was accidentally sunk in a collision with the cruiser on 28 April 1908. Construction ''Gala'' was laid down on 1 February 1904 at the Yarrow shipyard at Poplar and launched on 7 January 1905. She was completed in April 1905. Her original armament was to be the same as the Turtleback torpedo boat destroyers that preceded her. In 1906 the Admiralty decided to upgrade the armament by landing the five 6-pounder naval guns and shipping three 12-pounder 8 hundredweight (cwt) guns. Two would be mounted abeam at the foc'x'le break and the third gun would be mounted on the quarterdeck. Pre-war After commissioning she was assigned to the East Coast Destroyer Flotilla of the 1st Fleet and based at Harwich Harwich is a t ...

HMS Attentive (1904)
HMS ''Attentive'' was one of two scout cruisers built for the Royal Navy during the first decade of the 20th century. Completed in 1905 the ship was placed in reserve until she was commissioned in 1907 as part of the Home Fleet. She then spent the next seven years moving on and off of active service in British waters. The ship sank one destroyer and damaged two others in collisions. ''Attentive'' was assigned to coastal defence duties when the First World War began in 1914, and spent most of the war assigned to the Dover Patrol. She played a minor role in the Zeebrugge Raid in early 1918 and was then assigned to escort convoys to Gibraltar. The ship was sent to the White Sea later in the year to support the unsuccessful North Russia intervention in the Russian Civil War. ''Attentive'' paid off at the end of 1918 and was sold for scrap in 1920. Design and description The ''Adventure''-class ships were one of four classes of scout cruisers ordered by the Admiralty.

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 used t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birkenhead
Birkenhead (; cy, Penbedw) is a town in the Metropolitan Borough of Wirral, Merseyside, England; historically, it was part of Cheshire until 1974. The town is on the Wirral Peninsula, along the south bank of the River Mersey, opposite Liverpool. At the 2011 census, it had a population of 88,818. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution. Birkenhead Park and Hamilton Square were laid out as well as the first street tramway in Britain. The Mersey Railway connected Birkenhead and Liverpool with the world's first tunnel beneath a tidal estuary; the shipbuilding firm Cammell Laird and a seaport were established. In the second half of the 20th century, the town suffered a significant period of decline, with containerisation causing a reduction in port activity. The Wirral Waters development is planned to regenerate much of the dockland. Toponymy The ... [...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 ...

Russo-Japanese War
The Russo-Japanese War ( ja, 日露戦争, Nichiro sensō, Japanese-Russian War; russian: Ру́сско-япóнская войнá, Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1905 over rival imperial ambitions in Manchuria and the Korean Empire. The major theatres of military operations were located in Liaodong Peninsula and Mukden in Southern Manchuria, and the Yellow Sea and the Sea of Japan. Russia sought a warm-water port on the Pacific Ocean both for its navy and for maritime trade. Vladivostok remained ice-free and operational only during the summer; Port Arthur, a naval base in Liaodong Province leased to Russia by the Qing dynasty of China from 1897, was operational year round. Russia had pursued an expansionist policy east of the Urals, in Siberia and the Far East, since the reign of Ivan the Terrible in the 16th century. Since the end of the First Sino-Japanese War in 1895, Japan had feared Russian en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Steam Engine
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 st ...

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 (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] |
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 ...
