Speed sailing is the art of sailing a craft as fast as possible over a predetermined route, and having its overall or peak speed recorded and accredited by a regulatory body. The term usually refers to sailing on water, even though sailing on land and ice is progressively faster because of the lower friction involved. The World Sailing Speed Record Council is the body authorized by the World Sailing to confirm speed records of sailing craft (boats or sailboards) on water (not on ice or land).
