Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water, on ice (iceboat) or on land over a chosen course, which is often part of a larger plan of navigation.
A yacht is a sail- or motor-propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.
A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface.
The koch was a special type of small one- or two-mast wooden sailing ships designed and used in Russia for transpolar voyages in ice conditions of the Arctic seas, popular among the Pomors.
The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15.
Tacking or coming about is a sailing maneuver by which a sailing craft, whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. Sailing vessels are unable to sail higher than a certain angle towards the wind, so "beating to windward" in a zig-zag fashion with a series of tacking maneuvers, allows a vessel to sail towards a destination that is closer to the wind that the vessel can sail directly.
The International DN is a class of iceboat. The name stands for Detroit News, where the first iceboat of this type was designed and built in the winter of 1936–1937. Archie Arrol was a master craftsman working in the Detroit News hobby shop, and together with iceboaters Joe Lodge and Norman Jarrait designed a racing boat they called the "Blue Streak 60", later to become known as the "DN 60". In 1937 a group of 50 laymen worked with Archie in the hobby shop to produce the first fleet of the new iceboats. These first boats broke during the initial season, and after Jarrait and Lodge modified the design to increase the strength, the group got back together to build a second set of iceboats in 1938.
Land sailing, also known as sand yachting, land yachting or dirtboating, entails overland travel with a sail-powered vehicle, similar to sailing on water. Originally, a form of transportation or recreation, it has evolved primarily into a racing sport since the 1950s.
The Moth is a small development class of sailing dinghy. Originally a small, fast home-built sailing boat designed to plane, since 2000 it has become an expensive and largely commercially produced boat designed to hydroplane on foils though many are still built at home, typically at much lower cost.
A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed. A sailing hydrofoil can achieve speeds exceeding double and in some cases triple the wind speed.
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.
The Butterfly is a one-design sailing dinghy, originally designed for a crew of two, but now most commonly raced single-handed. It was designed in 1961 in Libertyville, Illinois by John Barnett. The 12-foot (3.7 m) hull is a scow design. The craft has a stayed 18-foot (5.5 m) mast set as a Marconi rig with a single mainsail with a 75-square-foot (7.0 m2) surface area. The cockpit is 15 ½" deep, exceptionally deep for this size of sailboat, and can accommodate an adult up to 6 feet in height.
Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack that is increasingly smaller. At the same time, such vehicles are subject to relatively low forward resistance, compared with traditional sailing craft. As a result, such vehicles are often capable of speeds exceeding that of the wind.
High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail. Faster-than-the-wind sailing means that the apparent wind angle experienced on the moving craft is always ahead of the sail. This has generated a new concept of sailing, called "apparent wind sailing", which entails a new skill set for its practitioners, including tacking on downwind points of sail.
Forces on sails result from movement of air that interacts with sails and gives them motive power for sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and sail-powered land vehicles. Similar principles in a rotating frame of reference apply to windmill sails and wind turbine blades, which are also wind-driven. They are differentiated from forces on wings, and propeller blades, the actions of which are not adjusted to the wind. Kites also power certain sailing craft, but do not employ a mast to support the airfoil and are beyond the scope of this article.
The Water Wag is the oldest one-design dinghy in existence, having been devised in 1886 and formalised as a one-design class in Ireland in 1887. It was last modified in 1900. The class is still sailed to this day, notably with large Water Wag fleets racing during summer evenings from Dún Laoghaire harbour on Dublin Bay. The Water Wag class is administered by the Water Wags club, based in Dún Laoghaire.
The following outline is provided as an overview of and topical guide to sailing:
The Mary Taylor was a 19th-century yacht and Sandy Hook pilot boat, built at the Hathorne & Steers shipyard in 1849 for Captain Richard Brown. She was designed by George Steers with a new radical design with a long thin bow and wide stern, which made her faster than any other boat in her class. This design proved successful and led to the famous yacht America, which won the America's Cup in 1851. The Mary Taylor sank after colliding with the schooner Fairhaven in 1863. She was replaced by the Mary E. Fish.
Jane Wiswell Pegel is an American sailor, on water and on ice, who was elected into the United States' National Sailing Hall of Fame in 2021.
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. By extension, "sail plan" describes the arrangement of sails on a craft. A sailing craft may be waterborne, an iceboat, or a sail-powered land vehicle.
