Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
Sails are classified as "triangular sails", "quadrilateral fore-and-aft sails" (gaff-rigged, etc.), and "square sails". [38] The top of a triangular sail, the head, is raised by a halyard, The forward lower corner of the sail, the tack, is shackled to a fixed point on the boat in a manner to allow pivoting about that point—either on a mast, e ...
The lateen sail can also be tacked by loosening the yard upper brace, tightening the lower brace until the yard is in vertical position, and twisting the yard on the other side of the mast by a tack. Another way of tacking with a lateen sail is to loosen the braces, lift the yard vertical, detach the sheet and tack, and turn the sail on the ...
A jib is a triangular sail that sets ahead of the foremast of a sailing vessel. Its forward corner is fixed to the bowsprit, to the bows, or to the deck between the bowsprit and the foremost mast. Jibs and spinnakers are the two main types of headsails on a modern boat.
Defined by sail plan. All masts have fore-and-aft sails. Schooner: fore-and-aft rigged sails, with two or more masts, the aftermost mast taller or equal to the height of the forward mast(s) All masts have square sails. Brig: two masts, square rigged (may have a spanker on the aftermost) Full-rigged ship: three or more masts, all of them square ...
A lug sail is an asymmetric quadrilateral sail suspended on a spar and hoisted up the mast as a fore-and-aft sail. A mizzen sail is a small triangular or quadrilateral sail at the stern of a boat. A steadying sail is a mizzen sail on motor vessels such as old-fashioned drifters and navy ships (such as HMS Prince Albert). The sail's prime ...
Cross-cut sails have the panels sewn parallel to one another, often parallel to the foot of the sail, and are the least expensive of the two sail constructions. Triangular cross-cut sail panels are designed to meet the mast and stay at an angle from either the warp or the weft (on the bias) to allow stretching along the luff, but minimize ...
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.
