Longman Dictionary of Contemporary English
n. A ship with masts and sails, powered by the wind.
n. a vessel that is powered by the wind; often having several masts [syn: sailing vessel]
A modern sailing ship is any large wind-powered vessel. Traditionally a sailing ship (or simply ship) is a sailing vessel that carries three or more masts with square sails on each. Large sailing vessels that are not ship-rigged may be more precisely referred to by their sail rig, such as schooner, barque (also spelled "bark"), brig, barkentine, brigantine or sloop.
