Sailing ropes, also known as rigging, are essential components of a sailing vessel. TYES is an acronym for the four main types of rope used in sailing: Topsail halyards, Yacht braid, Endeavour rope, and Sheet rope. Topsail halyards are used to raise and lower the sails, yacht braid is used for mooring lines, Endeavour rope is used for anchor lines, and sheet rope is used for controlling the sails. All of these ropes are essential for sailing and must be maintained regularly.
