The term 'Nautical Pole' refers to the four main components of a sailing vessel: a SPAR, a MAST, a SPRIT, and a BOOM. A SPAR is a long pole used for support, such as a yardarm or bowsprit. A MAST is a tall vertical pole used to support sails and rigging. A SPRIT is a pole that extends from the MAST to the bow of the boat, and is used to support the sail. Finally, a BOOM is a horizontal pole attached to the MAST, used to control the angle of the sail. Together, these four components form the nautical pole of a sailing vessel.
