In the 18th and 19th centuries, a sloop-of-war was a small sailing warship with a single gun deck which carried between ten and eighteen cannons. A brig sloop had two masts and a ship sloop had three, because a brig in those days was a one or two masted vessel – to be a ship it had to have three or more masts. A ship sloop was generally an equivalent of a corvette. A sloop-of-war was smaller than a sailing frigate.
A sloop-of-war was quite different from a civilian sloop, which was a general term for a single masted vessel.
Successive generations of guns became larger in the second half of the 19th century, so by the 1880s even the most powerful warships had less than a dozen large calibre guns. The term had by then become much less precise, meaning a small warship with a single gun-deck and which was bigger than a gunboat. Especially famous were British mass-produced sloops of the "Flower" class of the First World War. By the Second World War it had come to mean a small warship armed with one or two 4-inch guns and depth charges. After the Second World War, the sloops were replaced by frigates.
In sailing, a sloop is a vessel with a single mast on which is hoisted a fore-and-aft rigged mainsail and a single jib, plus extras such as a spinnaker.
A marconi sloop is the optimal rig for upwind sailing, and consequently sloops are very popular with amateur sailors and yachtsmen, and for racing.
To maximize the amount of sail carried, the classicalsloop may use a bowsprit, which is essentially a fixed boom that projects from the front of the boat.

The most famous sloop would probably be HMS Speedy The sloop HMS Speedy was commanded by Thomas Cochrane in which he achieved his most famous exploit, the capture of the Spanish xebec El Gamo, 32 guns and 319 men compared to Speedy's 14 guns and 54 men, on 6 May 1801.
