The purpose of D/LAB is to make the best Foiling gear using the best materials and construction methods on this planet, no holds barred.

The Foil Assist D/LAB mast is the lightest, stiffest, and lowest-drag mast in the Foil Assist range, delivering the highest level of performance. It’s ideal for prone foiling in small to medium waves and for connecting bumps on downwinders.

The Foil Assist Set D/LAB includes the following items:

eMast D/LAB Set

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 molded into the mast profile, positioned 17 cm below the top plate, minimizing 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 and fuselage just like a conventional foil mast and is compatible with most brands' foilboards.

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.

Note: The eMast D/LAB features a 3BS connection and is compatible with Duotone and Armstrong foils when used with our specially designed fuselage.

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, weight, setup and the conditions, the Foil Assist batteries provide 25 to 40 minutes of runtime per charge.
