Ship Pole is a term used to describe the three main masts of a sailing vessel. The first MAST is called the SPAR, which is a wooden pole used to support the sails. The second MAST is the MAST, which is the tallest and most important of the three masts. The third MAST is the Mizzzenmast, which is the shortest of the three masts and is located at the stern of the ship. Together, these three masts form the Ship Pole.
