The term 'Sail Spars' refers to the poles or spars used to support the sails of a sailing vessel. The spars are typically made of wood, metal, or composite materials and are attached to the mast and boom of the boat. The spritsail is a type of sail that is supported by a spritsail yard, which is a spar that runs diagonally from the mast to the peak of the sail. This type of sail is often used on smaller boats.
