DETAILED DESCRIPTION
Assistance that makes take-off easier
The eMast AL delivers significant thrust. This helps you get on foil earlier and maintain speed in light wind. You'll immediately feel the difference during takeoff and re-acceleration. This makes downwinds and light wind wing sessions more accessible.
Integration designed to limit drag
The motor pod is integrated into the mast profile, 17 cm below the plate. It features internal cables and a foldable 2-blade propeller that only deploys when activated. On the water, this means a cleaner glide when the assist is inactive and a smooth transition when you accelerate.
Stiffness and precision from the aluminum mast
The aluminum mast, with its surf-inspired profile, offers exceptional stiffness for immediate response when loaded. This gives you precise control in carving and tracking, which is especially useful for compact foils and engaged maneuvers.
Modularity and multi-brand compatibility
This kit is designed for easy integration with other systems: fuselage adapters are available for Duotone and ten other common brands. This means you can use the eMast AL with a wide range of foils and boards equipped with standard US rails.
Boost Adjustment Options and Accessories
You can choose between plastic or aluminum propellers to fine-tune the ride feel: opt for more power for tight turns and smaller foils, or a smoother boost for progressive take-offs. The battery box integrates the receiver for a stable radio link with the ring remote.
Range and Practical Management
This kit comes without a battery, charger, or remote. To maximize your range, we recommend pairing it with Front Wings of at least 900 cm² and boards with ample volume.
