A halyard is a rope or line, usually made of nylon or polyester, that is used to raise, lower or adjust the sails of a sailboat. It is attached to the sails and a pulley system called the masthead, which allows the sailor to control the angle and position of the sails to catch the wind and propel the boat forward. Halyards can differ in size, depending on the size and type of boat, but they are an important part of sailing and are essential for safely navigating any vessel.
