Originally classed as a steam vessel (SV3), her classification would be changed to a Third Class Sloop. She initially served in the Mediterranean, prior to her tug of war with the Rattler. She spent her time in the Americas and mainly on the anti-slavery patrol off the west coast of Africa.

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] |
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] |
Portsmouth
Portsmouth ( ) is a port and city in the ceremonial county of Hampshire in southern England. The city of Portsmouth has been a unitary authority since 1 April 1997 and is administered by Portsmouth City Council. Portsmouth is the most densely populated city in the United Kingdom, with a population last recorded at 208,100. Portsmouth is located south-west of London and south-east of Southampton. Portsmouth is mostly located on Portsea Island; the only English city not on the mainland of Great Britain. Portsea Island has the third highest population in the British Isles after the islands of Great Britain and Ireland. Portsmouth also forms part of the regional South Hampshire conurbation, which includes the city of Southampton and the boroughs of Eastleigh, Fareham, Gosport, Havant and Waterlooville. Portsmouth is one of the world's best known ports, its history can be traced to Roman times and has been a significant Royal Navy dockyard and base for centuries. Portsm ...

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 (nautical), beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in foot (length), feet, from the stem (ship), stem to the sternpost; * ''Beam (nautical), 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 capaci ... [...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 mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. 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 types of piston engines, as well as turbines, electric motors and other machinery. 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, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the steam ...

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 ...

Paddle Sloops Of The Royal Navy
A paddle is a handheld tool with an elongated handle and a flat, widened distal end (i.e. 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). It is different to an oar (which is similar in shape and performs the same function via rowing) in that the latter is attached to the watercraft via a fulcrum. However, 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 (i.e. paddle steamer). *A number of games (e.g. ping-pong), a "paddle" or "bat" is a small racket used to strike a ball. *A mixing paddle is an agitator device used to stir and more thoroughly mix separate ingredients within a mixture. *A spanking paddle is used in corporal punishment, typically to forcefully ...
