The term 'sailboat part' can refer to a variety of components that make up a sailboat. The most common sailboat part is the MAST, which is a vertical pole or spar that supports the sails and rigging. The MAST is typically made of wood, aluminum, or fiberglass and is usually the tallest part of the boat. It is held in place by stays and shrouds, which are cables that run from the top of the MAST to the deck. The MAST also supports the boom, which is a horizontal spar that holds the bottom edge of the sail.
