A mizzen mast is a vertical pole on a sailing vessel, typically located towards the rear of the ship. It is part of a three-masted rig, which includes the main mast and the foremast. The mizzen mast supports the mizzen sail, helping to balance the ship and improve its maneuverability. In traditional sailing ships, the mizzen mast plays a crucial role in steering and stability. It allows sailors to adjust the sails for better wind capture, enhancing the vessel's performance. The design and placement of the mizzen mast can vary among different types of ships, such as schooners and brigs.
