A small single-masted, sharp-built broad vessel, commonly navigated in the English Channel, furnished with a straight running bowsprit, occasionally run in horizontally on the deck; except for which, and the largeness of the sails, they are rigged much like sloops. Either clincher or carvel-built, no jib-stay, the jib hoisting and hanging by the halliards alone. She carries a fore-and-aft main-sail, gaff-topsail, stay-foresail, and jib. The name is derived from their fast sailing. The cutter (as H.M.S. Dwarf) has been made to set every sail, even royal studding-sails, sky-scrapers, moon-rakers, star-gazers, water and below-water sails, that could be set by any vessel on one mast. One of the largest which has answered effectually, was the Viper, of 460 tons and 28 guns; this vessel was very useful during the American war, particularly by getting into Gibraltar at a critical period of the siege.
