Sloop

A sloop (from Dutch sloep, in turn from French chaloupe) is a sail boat with a single mast and a fore-and-aft rig comprising a mainsail and a single foresail (or headsail). By comparison, a cutter has a mainsail and at least two foresails, and its mast may be set further aft than on a sloop. The so-called "Friendship Sloop" has more than one foresail, and is, strictly-speaking, a cutter.
