Racer-class Sloop
The ''Racer''-class sloop also known as the ''Cordelia'' class of swift cruisers was an 11-gun wooden screw sloop-of-war, sloop class of five ships built for the Royal Navy between 1855 and 1860. Design Built of a traditional wooden construction, the ''Racer'' class were a lengthened version of the , which in turn had been intended as "type of screw vessel below the Cruizer-class sloop, ''Cruizer''". The extra length gave greater speed, and combined with a considerable increase in power, this gave a speed of about , rather more than the of the previous class.Winfield (2004) p.216 The class were armed with a single 32 pounder 58 cwt, 32-pounder gun (58 cwt) gun on a pivot mount and ten 32-pounder (25 cwt) carronades on the broadside. These guns were all smoothbore muzzle-loading, and were little changed from the standard guns of Nelson's era.Bastock, p.29. Propulsion was provided by a two-cylinder horizontal single-expansion steam engine developing and driving a single screw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sloop-of-war
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy.

Barque
A barque, barc, or bark is a type of sailing vessel with three or more masts having the fore- and mainmasts rigged square and only the mizzen (the aftmost mast) rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above. Etymology The word "barque" entered English via the French term, which in turn came from the Latin ''barca'' by way of Occitan, Catalan, Spanish, or Italian. The Latin ''barca'' may stem from Celtic ''barc'' (per Thurneysen) or Greek ''baris'' (per Diez), a term for an Egyptian boat. The ''Oxford English Dictionary'', however, considers the latter improbable. The word ''barc'' appears to have come from Celtic languages. The form adopted by English, perhaps from Irish, was "bark", while that adopted by Latin as ''barca'' very early, which gave rise to the French ''barge'' and ''barque''. In Latin, Spanish, and Italian, the term ''barca'' refers to a small boat, not a full-sized ship. French infl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sloop Classes
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is sometimes fill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Classes Of The Royal Navy
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, a ...

HMNB Devonport
His Majesty's Naval Base, Devonport (HMNB Devonport) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England. The base began as Royal Navy Dockyard in the late 17th century, but shipbuilding ceased at Devonport in the early 1970s, although ship maintenance work has continued. The now privatised maintenance facilities are operated by Babcock International Group, who took over the previous owner Devonport Management Limited (DML) in 2007. DML had been running the Dockyard since privatisation in 1987. From 1934 until the early 21st century the naval barracks on the site was named HMS ''Drake'' (it had previously been known as HMS ''Vivid'' after the base ship of the same name). The name HMS ''Drake'' and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deptford Dockyard
Deptford Dockyard was an important naval dockyard and base at Deptford on the River Thames, operated by the Royal Navy from the sixteenth to the nineteenth centuries. It built and maintained warships for 350 years, and many significant events and ships have been associated with it. Founded by Henry VIII in 1513, the dockyard was the most significant royal dockyard of the Tudor period and remained one of the principal naval yards for three hundred years. Important new technological and organisational developments were trialled here, and Deptford came to be associated with the great mariners of the time, including Francis Drake and Walter Raleigh. The yard expanded rapidly throughout the sixteenth and seventeenth centuries, encompassing a large area and serving for a time as the headquarters of naval administration, and the associated Victualling Yard became the Victualling Board's main depot. Tsar Peter the Great visited the yard officially incognito in 1698 to learn shi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 docky ...

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carronade
A carronade is a short, smoothbore, cast-iron cannon which was used by the Royal Navy. It was first produced by the Carron Company, an ironworks in Falkirk, Scotland, and was used from the mid-18th century to the mid-19th century. Its main function was to serve as a powerful, short-range, anti-ship and anti-crew weapon. The technology behind the carronade was greater dimensional precision, with the shot fitting more closely in the barrel thus transmitting more of the propellant charge's energy to the projectile, allowing a lighter gun using less gunpowder to be effective. Carronades were initially found to be very successful, but they eventually disappeared as naval artillery advanced, with the introduction of rifling and consequent change in the shape of the projectile, exploding shells replacing solid shot, and naval engagements being fought at longer ranges. History The carronade was designed as a short-range naval weapon with a low muzzle velocity for merchant ships, ... [...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" ( en-em , burthen , enm , byrthen ), 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 measurem ...

Cruizer-class Sloop
The ''Cruizer'' class was a class of six 17-gun wooden screw sloops built for the Royal Navy between 1852 and 1856. Design The wooden sloops of the ''Cruizer'' class were designed under the direction of Lord John Hay, and after his "Committee of Reference" was disbanded, their construction was supervised by the new Surveyor of the Navy, Sir Baldwin Walker. A pair of ships named ''Cracker'' and ''Hornet'' had been ordered from Deptford and Woolwich in April 1847 as "steam gun schooners", with the intention of ordering four more. They were suspended in August 1847, and the new ships ''Cruizer'' and ''Hornet'' were re-ordered on 1 November 1850. ''Harrier'' was ordered in 1851, ''Fawn'' in 1852, and both ''Falcon'' and ''Alert'' on 2 April 1853. ''Cruizer'' differed from the rest of the class in having a lower-rated geared engine and a displacement of 960 tons, compared to 1,045 tons for the rest of the class.

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the World War II, Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority ...
