A barque, barc, or bark is a type of sailing vessel with three or more masts having the fore- and mainmasts rigged square and only the mizzen (the aftmost mast) rigged fore-and-aft. Until fore-and-aft rigs were applied to large ships to reduce crew sizes, the term was often used for any small sailing vessel. In poetic use, a bark can be any sailing ship or boat. Barquentine ships consisted of three or more masts, with square sails on foremost mast and gaff sails on the others. These middle-sized ships often sailed within Northern European waters with variable winds. They were often used in the lumber trade from Scandinavia to Germany and England across the Baltic and North Seas. Barquentine ships feature a simpler rig and needed a smaller crew than that of a barque but did not sail as well in following winds.
