Sailing

Sailing is the art of controlling a boat with large (usually fabric) foils called sails. By changing the rigging, rudder, and sometimes the keel or centre board, a sailor manages the force of the wind on the sails in order to change the direction and speed of a boat. 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 outboard and modified car engines have become available even in the poorest and most remote areas. In most countries people enjoy sailing as a recreational activity or as a sport. Recreational sailing or yachting can be divided into racing and cruising. Cruising includes extended trips, short trips within sight of land, and daysailing.
