A large sea-going vessel with masts and sails, particularly one with three masts rigged with square sails. It is made up of hull, deck (q. v.), masts, yards, bow-sprit and rigging, ropes and chains. The front mast is the foremast, the middle mast the main-mast, and the hindmost the mizzen-mast, and when a fourth is used, the jigger. A full-rigged ship has from 21 to 24 sails, and a four-masted ship as many as 36 sails.
