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.).
A centreboard or centerboard (US) [1] is a retractable hull appendage which pivots out of a slot in the hull of a sailboat, known as a centreboard trunk (UK) or centerboard case (US). The retractability allows the centreboard to be raised to operate in shallow waters, to move the centre of lateral resistance (offsetting changes to the sailplan ...
Sailing hydrofoils achieve boat speeds up to twice the speed of the wind, as did the AC72 catamarans used for the 2013 America's Cup. [20] Ice boats can sail up to five times the speed of the wind. [21] [22] Lateral force is a reaction supplied by the underwater shape of a sailboat, the blades of an ice boat and the wheels of a land sailing craft.
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
Fore-and-aft rigs include: Rigs with one mast: the proa, the catboat, the sloop, the cutter. Rigs with two masts: the ketch, the yawl. Rigs with two or more masts: the schooner. Barques and barquentines are partially square rigged and partially fore-and-aft rigged. A rig which combines both on a foremast is known as a hermaphroditic rig.
Sails are typically attached to the vessel and manipulated by sailors via a combination of mast, spars, and ropes. 2. The power harnessed by a sail or sails to propel a vessel. 3. To use sail power to propel a vessel. 4. A trip in a boat or ship, especially a sailboat or sailing ship. 5.
Felucca on the Nile at Luxor. A felucca [a] is a traditional wooden sailing boat with a single sail used in the Mediterranean, including around Malta and Tunisia.However, in Egypt, Iraq and Sudan (particularly along the Nile and in the Sudanese protected areas of the Red Sea), its rig can consist of two lateen sails as well as just one.
Mast-aft rig. A mast-aft rig is a sailboat sail-plan that uses a single mast set in the aft half of the hull. The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production sailboats.
