Take your foiling to the next level with the Duotone Foil Assist Set AL – a plug-and-play system that gives you the extra boost exactly when you need it.
The Foil Assist Set AL includes the following items:eMast AL SetBuilt from lightweight aluminum and measuring 84 cm, the eMast AL is incredibly stiff and provides a direct feel.
The motor pod is fully integrated into the mast and positioned slightly behind the leading edge, 17 cm below the top plate, to minimise drag even during touchdowns. It features a two-blade folding propeller that reduces drag for effortless glide on the wave. Thanks to the integrated gear system, the propeller unfolds instantly, providing a smooth transition as you kick out of the wave and power back out.
The eMast mounts to your board just like a conventional foil mast.
Note: A fuselage adapter is required to mount a fuselage onto the eMast. In addition to the Duotone adapter, we offer ten other options to help you combine the Foil Assist with your existing foil setup. The adapter is not included and must be purchased separately.
Tip: For optimal battery performance, pair the eMast with a front wing of at least 900 cm² and a board with a minimum volume of 35 L.
eHarness Set The Foil Assist is powered by two compact batteries housed in a waterproof box mounted on a lightweight eHarness (approx. 3.76 kg). This keeps your board free from extra weight and drag. With the batteries placed on your hips, the natural, fluid feel of foiling is preserved while still giving you full freedom of movement. The eHarness is buoyant and easy to remove. A cable runs neatly along the shorter board leash and connects the batteries to the eMast. The receiver integrated into the battery box ensures a stable and reliable connection between the remote and the motor throughout your entire session.
eRemote Watch Ring Set The Foil Assist Remote - a waterproof smartwatch-style controller with a finger ring - keeps your hands free, making it easier to push up on the board, paddle, duck dive, carve or handle a wing. Activate the motor with a double-click on the + button, and control the speed by pressing and holding either the + or - button.
Battery Charger Set The charger can fully charge both batteries in under one hour and also includes a discharge function that helps maintain long-term battery health.
Airtravel-friendly Battery Set Depending on your skill level, setup and the conditions, the Foil Assist batteries provide 30 to 60 minutes of runtime per charge.

Tech Features
Stiff mast for a direct response: The stiff aluminum mast features a rigid, surf-inspired profile that ensures precise control and instant responsiveness, minimizing drag for smoother and more efficient sessions. Highly modular: Every component of the Foil Assist system is cross-compatible with the other eMast options, making it easy to expand your setup. The Foil Assist Mast AL can be mounted to any brand’s foilboard with standard US foil tracks. A fuselage adapter is required to attach the fuselage to the eMast. In addition to the Duotone adapter, we offer ten more options to help you combine the eMast with your existing foils. Low drag through seamless integration: The motor pod is fully integrated into the mast and positioned slightly behind the leading edge, 17 cm below the top plate, to minimize drag even during touchdowns. This design also makes assembling the mast easier. Reliable signal transmission: The Bluetooth connection between the remote and the Foil Assist system is very stable, as the receiver is integrated into the lid of the battery box. This design prevents the connection from being interrupted by water. Different boost options: Customize your ride with different propellers — plastic or aluminum — to dial in your perfect setup. Choose between powerful assistance that enables you to ride smaller foils and perform sharper turns, or go for a smoother boost for easy takeoffs and foiling. Folding propeller for low drag: The two-blade folding propeller reduces drag, allowing for effortless gliding on the wave. Thanks to its integrated gear system, the propeller unfolds instantly, providing a smooth transition as you kick out of the wave and power back out.
