Sail plan of a brig. A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail ...
A full-rigged ship or fully rigged ship is a sailing vessel with a sail plan of three or more masts, all of them square-rigged. [1] Such a vessel is said to have a ship rig or be ship-rigged , with each mast stepped in three segments: lower, top, and topgallant.
Sail plan of a sloop. Each rig may be described with a sail plan—a drawing of a vessel, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [4] By extension, "sail plan" describes the arrangement of sails on a vessel.
Downwind polar diagram to determine velocity made good at various wind speeds for a hypothetical displacement sailboat and sail plan. A velocity prediction program can translate sail performance and hull characteristics into a polar diagram , depicting boat speed for various windspeeds at each point of sail.
A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or ...

Diagram contrasting course made good to windward by tacking a schooner versus a square-rigged ship. Sailing vessels cannot sail directly into the wind. Instead, square-riggers must sail a course that is between 60° and 70° away from the wind direction [76] and fore-and aft vessels can typically sail no closer than 45°. [77]
