DETAILED DESCRIPTION
Take-off Assist
The Foil Assist Set AL provides 33 kg of thrust via a motor integrated into its 84 cm mast, making take-offs in prone, surf foil, or downwind significantly easier. You'll quickly find your feet, getting clear of the waves and powering up again without having to pump the board extensively.
Ride Feel and Control
The rigid aluminium mast, with its surf-inspired profile, delivers a direct response and precise control. You get a natural handling feel, which is useful for carving and initiating turns even at high speed.
Modularity and Compatibility
The system is designed to be modular: the mast mounts on standard US rails, and various fuselage adapters (not included) are available to connect your fuselage. This allows the Foil Assist to be integrated with many existing setups.
Battery Life and Ergonomics
The kit includes two batteries housed in a box on the harness, keeping the board free of extra weight. The connection between the ring remote and the box is stable, and the charger allows for quick recharges to keep your sessions going.
Safety and Control
The ring remote requires a double press to start and stops as soon as the button is released, minimising the risk of accidental starts. The propeller is foldable and only deploys when activated, reducing risk on contact with the water.
Pairing Advice
To get the most out of the batteries and the assist, Duotone recommends a front wing of at least 900 cm² and a board of at least 35 L. Remember to order the correct mast/fuselage adapter for your fuselage before mounting the mast.
