Duotone Foil Assist Set AL 2026
The Duotone Foil Assist Set AL 2026 is designed for riders who want more range, easier take-offs and extra power while keeping the natural, surf-like feeling of foiling. With its stiff 84 cm aluminium eMast, integrated motor, folding propeller, waterproof eHarness battery system and intuitive eRemote Watch Ring, this complete assist system gives you controlled electric support without turning your foil setup into a full eFoil.
Whether you are prone foiling, wing foiling, pumping back out after a wave or simply looking for more security in light wind and marginal conditions, the Foil Assist Set AL delivers smooth, reliable assistance exactly when you need it.
Key Features
- 84 cm aluminium eMast: Stiff, direct and responsive mast construction for precise foil control.
- Integrated motor pod: The motor is built into the mast profile to reduce drag and keep the ride smooth and efficient.
- Two-blade folding propeller: Reduces drag while gliding and opens instantly when assistance is activated.
- eHarness battery system: Two compact batteries are carried on the hips in a waterproof battery box, keeping the board free from extra weight.
- Wireless eRemote Watch Ring: Waterproof smartwatch-style remote with finger ring for hands-free control.
- Quick charger included: Charges both batteries in under one hour and includes a discharge function for battery care.
- Modular compatibility: Designed to work with Duotone and many other foil systems when used with the correct adapter.
- Travel-friendly battery concept: Compact battery setup designed for practical transport and everyday use.
Natural Foiling Feel with Extra Power
Unlike a traditional eFoil, the Duotone Foil Assist is made to support your existing foiling style. The batteries are carried in the eHarness instead of being mounted inside the board, helping to preserve the natural feeling of your foilboard. This keeps your setup lighter under your feet and allows you to pump, carve and glide with a more familiar foil sensation.
Low Drag Integrated Motor Design
The motor pod is fully integrated into the mast and positioned behind the leading edge, approximately 17 cm below the top plate. This design helps reduce drag, even during touchdowns, while keeping the mast easy to assemble and ride. The folding propeller further reduces resistance when gliding on a wave or pumping between sections.
Reliable Wireless Control
The included eRemote Watch Ring gives you simple and intuitive control while keeping your hands free. Activate the motor with a double-click and adjust speed with the plus and minus buttons. The receiver is integrated into the battery box lid, helping maintain a stable signal and reducing the chance of water interference.
Recommended Setup
For best performance, Duotone recommends using the Foil Assist with a front wing of at least 900 cm² and a board with a minimum volume of 35 litres. Runtime depends on your foil setup, riding style and conditions, with typical assistance time around 30–50 minutes per charge.
