Sloop.
(Nautical.) a. A foreand-aft rigged vessel with one mast, like a cutter, but having a jib-stay and standing bowsprit, which the cutter has not. b. Formerly a ship of war of a size between a corvette and a brig. War-vessels of 2,000 tons and upward, as large as line-of-battle ships in the days of Howe and Nelson, carrying 12 to 22 heavy guns, are now termed sloops.
