HMS Pigmy (1781)
Seven ships of the Royal Navy have been named ''Pigmy'': * , a 14-gun cutter captured by the French on 27 December 1781. Recaptured on 22 July 1782. Renamed HMS ''Lurcher'' on 31 May 1783 and HMS ''Pigmy'' in July 1783. ''Pigmy'' wrecked on 16 December 1796 during the night in Bigbury Bay, Devon. When she started to break up Captain A. Pullibank permitted the crew to go ashore via a hawser. Pullibank, his son, and some 10 of her crew of 60 were lost. The subsequent court martial acquitted her officers and crew of the loss. * , the former 10-gun cutter HMS ''Ranger'', renamed in 1782 and sold in 1784. * , the former French cutter ''Mutin'', captured on 2 October 1779. Renamed HMS ''Mutine'' on entry into Royal Navy service. Renamed HMS ''Pigmy'' on 20 January 1798. Wrecked on 9 August 1805. * HMS ''Pigmy'', was the 16-gun cutter , renamed in 1806 and wrecked on 5 March 1807. * , a 10-gun cutter/schooner sold in 1823. * , a paddle steamer scrapped in 1879. * , a composite screw gunb ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the 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 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 globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...
