A vertical pole or strut used in windsurfing to support the sail, or in foiling as the connection between the board and the underwater wings.
The word mast means different things depending on the sport. In windsurfing, the mast is a tall, flexible pole (typically 370–520 cm) that slides into the luff sleeve of the sail and provides its rigid structure. Windsurf masts are rated by stiffness (IMCS) and bend curve — matching the correct mast to your sail is critical for proper performance.
Carbon content ranges from 30% to 100%; more carbon means lighter and stiffer, but also more expensive. In foiling, the mast is the vertical strut that connects the board to the fuselage and wings underwater. Foil mast lengths typically range from 50 to 105 cm.
Shorter masts are easier to control and better for shallow water, while longer masts give more clearance over chop and allow higher riding. In sailing, the mast supports the mainsail and is the tallest structure on the boat.
Example usage
"Went from a 70 cm foil mast to a 90 cm — the extra height makes a huge difference in chop but it's harder to control."
