With a size of 84 cm, this mast is ideal for prone and downwind foiling and can also be used for wake foiling in tanker waves and wing foiling in light winds.

The motor pod is seamlessly integrated into the mast profile, positioned 17 cm below the top plate. This integration not only enhances aesthetics but also contributes to performance. The mast features internally routed cables, ensuring optimal glide and maximum maneuverability. Its rigid, surf-inspired profile provides precise control and instant responsiveness while minimizing drag for smoother, more efficient sessions.

Customize your ride with different propellers — plastic or aluminum — to dial in your perfect setup. Choose between powerful assistance that enables you to ride smaller foils and perform sharper turns, or go for a smoother boost for easy takeoffs and foiling. The folding gear propeller minimizes drag for effortless glide on the wave. Its integrated gear system allows the two-blade propeller to unfold instantly, delivering a seamless transition as you kick out of the wave and power back out.

All components of the Foil Assist system are compatible with the other mast options, allowing you to easily expand your setup. With a wide selection of fuselage adapters — including, in addition to Duotone, ten other options such as F-One, Armstrong, Gong, Axis, Lift, North, Code, Sab, AFS, and KT — the Foil Assist can be seamlessly combined with most foil systems. It mounts to the board just like a traditional mast.

To maximize battery runtime with your Foil Assist, we recommend using a front wing with a surface area of 900 cm² or larger, along with a board that has a minimum volume of 35 L.

Whether you're looking to enhance your sessions or push your performance, every detail of the Foil Assist Mast AL has been engineered for a seamless and intuitive assist experience in all conditions.
