The Duotone Foil Assist Mast D/LAB sets a new standard for powered foiling, delivering an exceptionally smooth ride from takeoff to touchdown.
Built from lightweight carbon and measuring 84 cm, the eMast D/LAB is the lightest and most advanced model in the Foil Assist lineup. Designed for unparalleled performance and control, the D/LAB emast has a slim, low-drag profile that ensures playful and precise turning, exceptional rigidity, and maximum speeds.
The motor pod is seamlessly moulded into the mast profile, positioned 17 cm below the top plate, minimising drag even during touchdowns. It features a two-blade folding propeller that reduces drag for effortless gliding 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 and fuselage just like a conventional foil mast and is compatible with most brands' foilboards.
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.
The eMast D/LAB features a 3BS connection and is compatible only with Duotone foils and Armstrong foils when used with our specially designed fuselage.
Designed for progressive watersports, this Duotone product balances performance, durability and ease of use.

Tech Features
Modular Design: 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 D/LAB can be mounted to any brand’s foilboard with standard US foil tracks. Because of the molded 3BS connection at the base plate, it is compatible only with Duotone foils and the specially designed fuselage for Armstrong foils.
Extremely low drag: The slim and extremely low drag profile ensures maximum performance for the intended foiling discipline. The super slim base plate design minimizes drag while pumping up on the foil, landing and touching down significantly.
Turning behavior: The riding characteristics of the eMast D/LAB same as the Mast Slim 2.0 D/LAB are extremely playful. The High Modulus Carbon fiber enables precise turning.
Low drag through seamless integration: The fully integrated motor pod, fixed at 17 cm below the top plate, and internally routed cables optimize glide and maneuverability, while allowing for easy assembly.
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.
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.
