Sailing

Sailing is the propulsion of a vehicle and the control of its movement with large (usually fabric) foils called sails. By changing the rigging, rudder, and sometimes the keel or centreboard, a sailor manages the force of the wind on the sails in order to move the vessel relative to its surrounding medium (typically water, but also land and ice) and change its direction and speed. Mastery of the skill requires experience in varying wind and sea conditions, as well as knowledge concerning sailboats themselves and a keen understanding of one's surroundings.

While there are still some places in the world where sail-powered passenger, fishing and trading vessels are used, these craft have become rarer as internal combustion engines have become economically viable in even the poorest and most remote areas. In most countries sailing is enjoyed as a recreational activity or as a sport. Recreational sailing or yachting can be divided into racing and cruising. Cruising can include extended offshore and ocean-crossing trips, coastal sailing within sight of land, and daysailing.

History

Sailing has been instrumental in the development of civilization, affording humanity greater mobility than travel over land, whether for trade, transport or warfare, and the capacity for fishing. The earliest representation of a ship under sail appears on a painted disc found in Kuwait dating between 5000 and 5500 BCE. Advances in sailing technology from the Middle Ages onward enabled Arab, Chinese, Indian and European explorers to make longer voyages into regions with extreme weather and climatic conditions. There were improvements in sails, masts and rigging; improvements in marine navigation, including the cross staff and quadrant, the development of sextant and reaching the celestial navigation.

Types of Sailing

Sailing can be conducted by various types of vessels, including sailboats, windsurfing, kitesurfing, dinghy sailing, yacht racing, catamaran sailing, and even cruising on large ships.

Sailing Techniques

Sailing techniques include the tack, where the bow of the boat turns through the wind, the jibe, where the stern of the boat turns through the wind, and the beating, where a course is made good against the wind by a series of tacks.

Sailing as a Sport

Sailing as a sport involves a variety of competitive sailing formats that are sanctioned through various sailing federations and yacht clubs. Racing disciplines include matches within a fleet of sailing craft, between a pair thereof or among teams. Additionally, there are specialized competitions that include setting speed records.
