Land sailing

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. Vehicles used in sailing are known as sail wagons, sand yachts, or land yachts. They typically have three (sometimes four) wheels and function much like a sailboat, except that they are operated from a sitting or lying position and steered by pedals or hand levers. Land sailing works best in windy flat areas, and races often happen on beaches, airfields, and dry lake beds in desert regions. Modern land sailors, generally known as "pilots", can go three to four times faster than the wind speed. A gust of wind is considered more beneficial in a land sailing race than a favorable windshift. A similar sport, known as ice yachting, is practiced on frozen lakes and rivers. Another variation is the Whike, which combines land sailing with bicycling and can therefore also be used in everyday traffic because it does not fully depend on wind. TOC The earliest text describing the Chinese use of mounting masts and sails on large vehicles is the Book of the Golden Hall Master written by the Daoist scholar and crown prince Xiao Yi, who later became Emperor Yuan of Liang (r. 552–554 AD). He wrote that Gaocang Wushu invented a "wind-driven carriage" which was able to carry thirty people at once. There was another built in about 610 for the Emperor Yang of Sui (r. 604–617), as described in the Continuation of the New Discourses on the Talk of the Times. European travelers from the 16th century onwards mentioned sailing carriages with surprise. In 1585, during the Chinese Ming Dynasty, Gonzales de Mendoza wrote that the Chinese had many coaches and wagons mounted with sails, and even depicted them in artwork of silk hanfu robes and on earthenware vessels. In the 1584 atlas Theatrum Orbis Terrarum written by the cartographer Abraham Ortelius (1527–1598), there are large Chinese carriages depicted with sails and masts.

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 bonded filaments, usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack, its angle with respect to the apparent wind.
Sailing
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ice (iceboat) or on land (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances.
Sailboat
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. List of sailing boat types Although sailboat terminology has varied across history, many terms have specific meanings in the context of modern yachting. A great number of sailboat-types may be distinguished by size, hull configuration, keel type, purpose, number and configuration of masts, and sail plan.
