A device made to lead a rope smoothly or fairly. May be made of plastic or wood or metal, and in a variety of forms. Some fairleads are open, for example those mounted on side-decks to prevent chafe of mooring lines, and others are closed as is the case with the Bullseye sheet lead. A fair lead is fixed to the boat, whereas a Dead-eye is usually free to move: for example a dead-eye may be attached to a sail.
