A premium mast for modern wing foiling

The GA-Foils UHM Carbon Mast 85 is the most advanced foil mast in the GA range, built for riders who want maximum precision and the most direct foil response possible. This mast is all about efficiency, low weight, and very high stiffness under load. On the water, that translates into a cleaner foil feel, better control at higher speed, and more predictable behaviour through turns and upwind riding.

Ultra High Modulus Carbon construction

The mast is made from 100% Ultra High Modulus Carbon, which is a very stiff type of carbon fiber used in more advanced constructions. Put simply, it flexes less under load and transfers energy more directly. That gives the foil a more immediate response to rider input, improves control, and reduces energy loss through unwanted flex.

This is especially noticeable if you want a fast, precise setup and are looking for a clear step up from more standard mast constructions.

Slim profile and low drag

The GA-Foils UHM Carbon Mast 85 features a slim 15 mm profile and a 118 mm chord. The chord is simply the front-to-back width of the mast profile. This shape has been refined to reduce drag in the water without giving up the stiffness needed for confident riding.

In practice, this means smoother glide, easier speed retention, and more stable foil handling. The constant profile through the full mast length also helps keep water flow clean and contributes to a more balanced, predictable feel in different conditions.

Performance on the water

The combination of very stiff UHM Carbon construction and a refined hydrodynamic profile makes this mast feel fast, reactive, and stable. On the water, that means quicker acceleration, better glide efficiency, more precise foil steering, and smoother flight overall.

This is a mast for riders who want to get the most out of a modern wing foil setup and are looking for a component with a clear performance focus.
