This is the ultimate Foil Assist package for riders who want maximum performance, a powerful boost, extended water time, and the most advanced low-drag mast system on the market. The Duotone Foil Assist D/LAB Bundle includes everything you need to unlock next-level efficiency, playful turning, and seamless assisted takeoffs, now complete with the high-performance SLS metal propellers and additional battery sets for longer sessions.
The fully integrated motor pod sits 17 cm below the top plate, keeping the profile extremely clean and low drag. All cables are routed internally for smooth water flow and easy assembly. The D/LAB mast uses High Modulus Carbon construction for an incredibly precise and reactive feel, giving riders the same lively turning and glide characteristics as the Mast Slim 2.0 D/LAB.
The folding two-blade propeller reduces drag while gliding or surfing and opens instantly when power is applied for a smooth transition back into boost. With customisable power settings and interchangeable propeller options, you can dial in the perfect amount of assistance for smaller foils, sharper turns, or easy takeoffs.
The Bluetooth receiver sits inside the battery-box lid, keeping the signal strong and reliable even when underwater. The entire system is modular and compatible across the Foil Assist range. It mounts to any board using standard US tracks, and with the 3BS base connection, it is compatible with Duotone foils and Armstrong foils using the dedicated fuselage.
This premium bundle includes extra battery sets so riders can stay on the water longer, train efficiently, or run back-to-back sessions without waiting for charge time. The SLS metal propellers give the highest torque, fastest pickup, and the most responsive ride feel — perfect for riders who want the absolute top performance from their setup.
A great addition to this kit (not included) is the Duotone Crest Oil, which we recommend for maintaining smooth, long-lasting bearing performance.
