An outrigger is a projecting structure on a boat, with specific meaning depending on types of vessel. Outriggers may also refer to legs on a wheeled vehicle that are folded out when it needs stabilization, for example on a crane that lifts heavy loads.
An outrigger describes any contraposing float rigging beyond the side (gunwale) of a boat to improve the vessel's stability. If a single outrigger is used it is usually but not always windward.The technology was originally developed by the Austronesian people. There are two main types of boats with outriggers: double outriggers (prevalent in maritime Southeast Asia) and single outriggers (prevalent in Madagascar, Melanesia, Micronesia and Polynesia). Multihull ships are also derived from outrigger boats.
In an outrigger canoe and in sailboats such as the proa, an outrigger is a thin, long, solid, hull used to stabilise an inherently unstable main hull. The outrigger is positioned rigidly and parallel to the main hull so that the main hull is less likely to capsize. If only one outrigger is used on a vessel, its weight reduces the tendency to capsize in one direction and its buoyancy reduces the tendency in the other direction.
On a keelboat, "outrigger" refers to a variety of structures by which the running rigging (such as a sheet) may be attached outboard (outside the lateral limits) of the boat's hull. The Racing Rules of Sailing generally prohibitsuch outriggers, though they are explicitly permitted on specific classes, such as the IMOCA Open 60 used in several major offshore races.
In fishing from vessels, an outrigger is a pole or series of poles that allow boats to trawl more lines in the water without tangling and simulates a school of fish.
In a rowing boat or galley, an outrigger (or rigger) is a triangular frame that holds the rowlock (into which the oar is slotted) away from the saxboard (or gunwale in gig rowing) to optimize leverage. Wooden outriggers appear on the new trireme around the 7th or 6th centuries BC and later on Italian galleys around AD 1300, while Harry Clasper (1812–1870), a British professional rower, popularised the use of the modern tubular-metal version and the top rowing events accepted the physiological and ergonomic advantages so acceded to its use in competitions. In recent decades, some manufacturers of racing shells have proposed wing-riggers which are reinforced arcs or flattened tubular projections akin to aircraft wings, instead of conventional triangular structures.

A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing square-rigged or fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast—schooners. Still others employ a combination of square and fore-and aft sails, including the barque, barquentine, and brigantine.
A sailboat or sailing boat is a boat propelled partly or entirely by sails and is smaller than a sailing ship. Distinctions in what constitutes a sailing boat and ship vary by region and maritime culture.
A sail plan is a description of the specific ways that a sailing craft is rigged, as discussed below. Also, the term “sail plan” is a graphic depiction of the arrangement of the sails for a given sailing craft.
A catamaran is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes.
A jibe (US) or gybe (Britain) is a sailing maneuver whereby a sailing vessel reaching downwind turns its stern through the wind, which then exerts its force from the opposite side of the vessel. For square-rigged ships, this maneuver is called wearing ship.
A trimaran is a multihull boat that comprises a main hull and two smaller outrigger hulls which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs.
A dugout canoe or simply dugout is a boat made from a hollowed tree. Other names for this type of boat are logboat and monoxylon. Monoxylon (μονόξυλον) is Greek -- mono- (single) + ξύλον xylon (tree) -- and is mostly used in classic Greek texts. In German, they are called Einbaum. Some, but not all, pirogues are also constructed in this manner.
This is a glossary of nautical terms; some remain current, while many date from the 17th to 19th centuries. See also Wiktionary's nautical terms, Category:Nautical terms, and Nautical metaphors in English. See the Further reading section for additional words and references.
Outrigger boats are various watercraft featuring one or more lateral support floats known as outriggers, which are fastened to one or both sides of the main hull. They can range from small dugout canoes to large plank-built vessels. Outrigger boats can also vary in their configuration, from the ancestral double-hull configuration (catamarans), to single-outrigger vessels prevalent in the Pacific Islands and Madagascar, to the double-outrigger vessels (trimarans) prevalent in Island Southeast Asia. They are traditionally fitted with Austronesian sails, like the crab claw sails and tanja sails, but in modern times are often fitted with petrol engines.

Waka are Māori watercraft, usually canoes ranging in size from small, unornamented canoes used for fishing and river travel to large, decorated war canoes up to 40 metres (130 ft) long.
Rowing is the act of propelling a boat using the motion of oars in the water by displacing water to propel the boat forward. Rowing and paddling are similar. However, rowing requires oars to have a mechanical connection with the boat, while paddles are hand-held and have no mechanical connection.
In watercraft, a racing shell is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is outfitted with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing.
In competitive rowing, the following specialized terms are important in the corresponding aspects of the sport:
The vinta is a traditional outrigger boat from the Philippine island of Mindanao. The boats are made by Sama-Bajau, Tausug and Yakan peoples living in the Sulu Archipelago, Zamboanga peninsula, and southern Mindanao. Vinta are characterized by their colorful rectangular lug sails (bukay) and bifurcated prows and sterns, which resemble the gaping mouth of a crocodile. Vinta are used as fishing vessels, cargo ships, and houseboats. Smaller undecorated versions of the vinta used for fishing are known as tondaan.
The log canoe is a type of sailboat developed in the Chesapeake Bay region. Based on the dugout, it was the principal traditional fishing boat of the bay until superseded by the bugeye and the skipjack. However, it is most famous as a racing sailboat, and races continue to be held.
A sailing yacht, is a leisure craft that uses sails as its primary means of propulsion. A yacht may be a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies here to sailing vessels that have a cabin with amenities that accommodate overnight use. To be termed a "yacht", as opposed to a "boat", such a vessel is likely to be at least 33 feet (10 m) in length and have been judged to have good aesthetic qualities. Sailboats that do not accommodate overnight use or are smaller than 30 feet (9.1 m) are not universally called yachts. Sailing yachts in excess of 130 feet (40 m) are generally considered to be superyachts.
Camakau are a traditional watercraft of Fiji. Part of the broader Austronesian tradition, they are similar to catamarans, outrigger canoes, or smaller versions of the drua, but are larger than a takia. These vessels were built primarily for the purposes of travelling between islands and for trade. These canoes are single hulled, with an outrigger and a cama, a float, with both ends of the hull being symmetrical. They were very large, capable of travelling open ocean, and have been recorded as being up to 70 ft in length.
Kaep is a traditional type of double-ended Proa sailboat native to Palau. Some of the essential design elements have also been adopted as a modern smaller multihull prototype variant.
