Sail Informatiounen a Links

  • 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.
  • Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail.
  • Sails may be attached to a mast, boom or other spar or may be attached to a wire that is suspended by a mast.
  • They are typically raised by a line, called a halyard, and their angle with respect to the wind is usually controlled by a line, called a sheet.
  • Battens may be used to extend the trailing edge of a Sail beyond the line of its attachment points.
  • Other non-rotating airfoils that power sailing craft include wingsails, which are rigid wing-like structures, and kites that power kite-rigged vessels, but do not employ a mast to support the airfoil and are beyond the scope of this article.
