Foil Masts

A foil mast (or simply mast) is the vertical connecting piece of a hydrofoil in watersports. It connects the board at the water surface with the fuselage and the wings underwater. Its main task is to define the board's lift height above the water and to transmit all the rider's steering inputs directly to the foil system.

Design and Function

• Material: Masts are made either of aluminum or carbon. Aluminum masts are robust and cost-effective, while carbon masts are significantly lighter, stiffer, and shaped more hydrodynamically, which minimizes twisting (torsion) in the water.
• The flow profile: A mast is shaped like a narrow airfoil. This allows it to cut through the medium with minimal water resistance and prevents the flow from separating at high speeds (cavitation).

Features and Characteristics

• Length defines the range: The mast length (usually between 60 and 105 cm) determines how high the board can hover above the water surface. A longer mast offers more room for waves and tighter turns, but also requires deeper water and more control.
• Aluminum (Durability & Entry-level): These masts are heavier but extremely resistant to bottoming out or transport damage. They offer solid stiffness for beginners and freeriders.
• Carbon (Direct feel & Performance): Carbon masts are extremely responsive. Since they hardly twist under load, every movement of the rider is transmitted to the wings without delay. They also cut through the water faster thanks to their thinner profile.
