DETAILED DESCRIPTION
Assistance for Getting Out of the Water
The Foil Assist Set AL provides 33 kg of thrust through a motor integrated into its 84 cm mast. This makes take-offs significantly easier for prone, surf foil, or downwind. You'll quickly find your rhythm, getting out of waves and powering up again without having to pump the board for long.
Ride Feel and Control
The rigid aluminum mast features a surf-inspired profile. It delivers direct response and precise control. You'll experience natural handling, perfect for carving and engaging turns even at high speeds.
Modularity and Compatibility
Designed for modularity, the mast mounts on standard US tracks. You'll find several fuselage adapters (not included) available to connect your fuselage, letting you integrate the Foil Assist with many existing setups.
Range and Ergonomics
The kit includes two batteries housed in a box attached to 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 recharging 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, minimizing the risk of unintentional activation. The propeller is foldable and only deploys upon activation, reducing risks during contact with water.
Pairing Advice
To fully leverage the batteries and assistance, Duotone recommends a Front Wing of at least 900 cm² and a board of at least 35 L. Remember to order the mast/fuselage adapter that fits your fuselage before mounting the mast.
