SLOOP. In general parlance is a vessel similar to a cutter; the bowsprit, however, is not running, and the jib is set on a standing stay with hanks. In North America the sloop proper sets only a main-sail and fore-sail, the latter jib-shaped, on a short standing bowsprit, and has no top-mast. The rig is greatly used for yachts there, and is most effective in moderate weather. Sloop in the royal navy is a term depending on the rank of the officer in command. Thus, the donkey frigate _Blossom_ was one cruise rated a _ship_, when commanded by a captain--the next, a _sloop_, because only commanded by a commander.
