eMast AL Cruise Set is the Foil Assist set designed for beginners and intermediates: slightly shorter mast, smooth electric support and an optional propeller guard (included) for extra safety.
More info
eMast AL Cruise Set is Duotone’s way to add electric assistance to your foil setup while keeping the true foiling feel. Strong, progressive thrust helps you get on foil earlier, run smaller foils and save energy on long upwind legs and downwind runs.
The motor pod is seamlessly integrated into the mast profile and the cables are routed internally for optimal glide and maneuverability. The folding propeller opens only when the motor is engaged and closes instantly when you release the control, reducing drag and improving safety.
Why riders choose it:
- Up to 33 kg of thrust for earlier takeoffs and smaller foils.
- Low-drag design: integrated motor pod and internal cable routing.
- Folding propeller: auto open/close for glide and safety.
- Batteries on the rider via harness for better balance and stable signal.
- Modular platform: motor and cables swap across the Foil Assist range.
Who it’s for:
- Riders who want more water time and longer runs with less fatigue.
- Those looking for real support in light-wind wing, prone waves, downwind and freeride.
- Intermediate to advanced foilers who want to run smaller, more reactive foils.
Key features:
- Integrated motor pod and internally routed cables.
- Folding propeller with instant stop when releasing the control.
- Compatible with US tracks and many foils (via adapters, depending on mast).
- Hands-free remote concept for paddling, pop-ups and wing handling.
