Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign because of the simultaneous existence of a crossless version of the flag, is an ensign (flag), 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 Monarchy of the United Kingdom, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy Dockyard
Royal Navy Dockyards (more usually termed Royal Dockyards) were state-owned harbour facilities where ships of the Royal Navy were built, based, repaired and refitted. Until the mid-19th century the Royal Dockyards were the largest industrial complexes in Britain. From the reign of Henry VII up until the 1990s, the Royal Navy had a policy of establishing and maintaining its own dockyard facilities (although at the same time, as continues to be the case, it made extensive use of private shipyards, both at home and abroad). Portsmouth was the first Royal Dockyard, dating from the late 15th century; it was followed by Deptford, Woolwich, Chatham and others. By the 18th century, Britain had a string of these state-owned naval dockyards, located not just around the country but across the world; each was sited close to a safe harbour or anchorage used by the fleet. Royal Naval Dockyards were the core naval and military facilities of the four Imperial fortresses - colonies which ena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheerness
Sheerness () is a port town and civil parish beside the mouth of the River Medway on the north-west corner of the Isle of Sheppey in north Kent, England. With a population of 13,249, it is the second largest town on the island after the nearby town of Minster, Swale, Minster which has a population of 16,738. Sheerness began as a fort built in the 16th century to protect the River Medway from naval invasion. In 1665 plans were first laid by the Navy Board for Sheerness Dockyard, a facility where warships might be provisioned and repaired. The site was favoured by Samuel Pepys, then Clerk of the Acts of the navy, for shipbuilding over Chatham, Medway, Chatham inland. After the raid on the Medway in 1667, the older fortification was strengthened; in 1669 a Royal Navy dockyard was established in the town, where warships were stocked and repaired until its closure in 1960. Beginning with the construction of a pier and a promenade in the 19th century, Sheerness acquired the added at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam. It is expressed in "tons burden" (, ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in feet, from the stem to the sternpost; * '' Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capacity in cubic feet, another method of volumetric measurement. The capacity in cubic feet i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominal Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alecto-class Sloop
The ''Alecto''-class steam vessels (SV3) later reclassed as Third Class Sloops, were designed by Sir William Symonds, the Surveyor of the Navy. The design was approved on 12 April 1839. Initially four vessels were ordered and completed. A fifth unit was ordered (Rattler), but was reordered as a screw propelled vessel. And a sixth unit had been ordered but was requested to be reordered to a different design. The screw driven ''Rattler'' participated in the first of three 'tug o- wars with the ''Alecto''. The vessels all participated during the Russian War. All had gone to the breakers by the mid-1860s. ''Alecto'' was the second named vessel since it was used for a 12-gun fireship, launched by King of Dover on 26 May 1781 and sold in 1802. ''Ardent'' was the fifth named vessel since it was used for a 64-gun third rate, launched at Blaydes of Hull on 13 August 1764, captured by the French off Plymouth on 17 August 1779, recaptured in April 1782 and renamed ''Tiger'' then sold in Ju ...

Surveyor Of The Navy
The Surveyor of the Navy, originally known as Surveyor and Rigger of the Navy, held overall responsibility for the design of British warships from 1745. He was a principal commissioner and member of the Navy Board from the inauguration of that body in 1546 until the Board was abolished in 1832 and its operational functions taken over by the Board of Admiralty. In 1860 the office was renamed ''Controller of The Navy'' until 1869, when the office was merged with that of the Third Naval Lord. The Department of the Surveyor of the Navy was replaced by the Department of the Director of Dockyards in 1872. History The office was established in 1546 under Henry VIII of England when the post holder was styled as ''Surveyor and Rigger of the Navy'' until 1611. Until 1745 the actual design work for warships built at each Royal Dockyard was primarily the responsibility of the individual Master Shipwright at that Royal Dockyard. For vessels built by commercial contract (limited to wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Sloops Of The Royal Navy
A paddle is a handheld tool with an elongated handle and a flat, widened end (the ''blade'') used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). A paddle is different from an oar (which can be similar in shape and perform the same function via rowing) – an oar is attached to the watercraft via a fulcrum. The term "paddle" can also be used to describe objects of similar shapes or functions: *A rotating set of paddle boards known as a paddle wheel is used to propel a steamboat or paddle steamer. *In a number of racquet sports (e.g. ping-pong and paddle ball), a "paddle" or "bat" is a short, solid racket used to strike a ball. *A mixing paddle is a device used to stir or mix separate ingredients within a mixture. *A spanking paddle is used in corporal punishment, typically to forcefully hit someone ( ...
