Amazon Class Sloop
The ''Amazon'' class was a class of six screw sloops of wooden construction built for the Royal Navy between 1865 and 1866. Construction Design Designed by Edward Reed, the Royal Navy Director of Naval Construction, they were equipped with a ram bow. The hull was of wooden construction, but they were the first class of sloops to incorporate a form of composite construction; they had iron cross beams while retaining wooden framing. Propulsion Propulsion was provided by a two-cylinder horizontal single-expansion steam engine by Ravenhill, Salkeld & Company driving a single screw. ''Vestal'' and ''Nymphe'' were fitted with three-cylinder Maudslay engines. Sail plan All the ships of the class were built with a barque A barque, barc, or bark is a type of sailing ship, sailing vessel with three or more mast (sailing), masts having the fore- and mainmasts Square rig, rigged square and only the mizzen (the aftmost mast) Fore-and-aft rig, rigged fore and aft.

Screw Sloop
A screw sloop is a propeller-driven sloop-of-war. In the 19th century, during the introduction of the steam engine, ships driven by propellers were differentiated from those driven by paddle-wheels by referring to the ship's ''screws'' (propellers). Other propeller-driven warships included screw frigates and screw corvette A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship.

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 stea ...

Barque
A barque, barc, or bark is a type of sailing ship, sailing vessel with three or more mast (sailing), masts having the fore- and mainmasts Square rig, rigged square and only the mizzen (the aftmost mast) Fore-and-aft rig, 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 language, Latin ''barca'' by way of Occitan language, Occitan, Catalan language, Catalan, Spanish, or Italian. The Latin ''barca'' may stem from Celtic language, Celtic ''barc'' (per Rudolf Thurneysen, Thurneysen) or Greek ''baris'' (per Friedrich Christian Diez, 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 language, Irish, was "bark", while that adopted by Latin as ''barca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Director Of Naval Construction
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.

Ram Bow
A ram was a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Ancient rams It was possibly developed in late Bronze age Egypt, but it only became widely used in later Iron age Mediterranean galleys. The ram was a naval weapon in the Greek/Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known for their ''diekplous'' and '' periplous'' tactics that disabled enemy ships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Start Point, Devon
Start Point is a promontory in the South Hams district in Devon, England, . Close to the most southerly point in the county, it marks the southern limit of Start Bay, which extends northwards to the estuary of the River Dart. The rocks of the point are greenschist and mica-schist, formed by metamorphism Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of , and often also at elevated pressure or in the presence of ch ... of Devonian sediments during a period of mountain building towards the end of the Carboniferous period. The name "Start" derives from an Anglo-Saxon word ''steort'', meaning a tail. This root also appears in the names of birds with distinctive tails, like the redstart. Features As a result of the many shipwrecks in the area, Start Point lighthouse was built in 1836 to alert ships to the danger of the point and its surrou ...

Miquelon Island
Miquelon (french: Île Miquelon) also known as ', is one of the islands of the archipelago of Saint Pierre and Miquelon, an Overseas collectivity of France located in the Gulf of St. Lawrence in the Atlantic Ocean, south of the coast of Newfoundland. Miquelon is situated between Le Cap Island to the north and Langlade Island (also called ''Petite Miquelon'') to the south. Toponymy The name Miquelon purportedly derived from a Basque nickname for "Michael" (''Mikel''). In 1579, the names Micquetõ and Micquelle appeared for the first time in French Basque mariner Martin de Hoyarçabal's maritime pilot. The name evolved over time into Miclon, Micklon, and finally Miquelon (''Mikelune'' in Basque). Geography Miquelon's coastline includes numerous sand and pebble beaches enclosing lagoons, as well as high rocky cliffs standing up to on the east coast. Its geology consists of slightly metamorphosed post-Ordovician volcanic rocks, mainly rhyolites with breccias, andesites and bas ...
