The Foil Assist Mast AL offers precise control, smooth glide, and versatile performance for prone, downwind, wake and light-wind wing foiling.
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 cm 2 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.
The following items are included in the eMast AL Set:
Foil Assist Mast AL including motor, bell, regular propeller blades, regular cable, and leash
Assist eMast cover
Motor bell & propeller cover
Screw set and tools
Cable fastener V
Spare regular propeller blades

Tech Features
Stiff mast for a direct response
The eMast AL Cruise is incredibly stiff and provides a direct, responsive feel.
Low drag through integrated motor pod
The fully integrated motor pod, positioned 15 cm above the fuselage, and internally routed cables optimize glide and maneuverability while allowing for easy assembly.
Different boost options
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.
Highly modular
Every component of the Foil Assist system is cross-compatible with the other eMast options, making it easy to expand your setup. The Foil Assist Cruise Mast AL can be mounted to any brand’s foilboard with standard US foil tracks.
Reliable signal transmission
The wireless connection between the remote and the Foil Assist system is very stable, as the receiver is integrated into the lid of the battery box. This design prevents the connection from being interrupted by water.
Folding propeller for low drag
The two-blade folding propeller reduces drag, allowing for effortless gliding on the wave. Thanks to its integrated gear system, the propeller unfolds instantly, providing a smooth transition as you kick out of the wave and power back out.
