1.) Assist Cruise - Efoil System

The Foil Assist Cruise Mast is ideal for flatwater cruising and foiling in swell, making it well-suited for entry-level and intermediate foilers looking to improve their skills and explore new spots.

The Foil Assist Set AL includes the following items:

eMast AL Cruise Set

With a length of 80 cm and built from lightweight aluminum, this mast is slightly shorter than the eMast AL, making it more suitable for novices while still performing well in swell and choppy waters. The eMast AL Cruise is incredibly stiff and provides a direct, responsive feel.

The powerful motor is mounted low on the mast, positioned just 15 cm above the fuselage, and features a two-blade folding propeller. The Cruise set also includes an optional guard for added protection from the propeller.

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.

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 paddle, or push up on the board. 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 50 minutes of runtime per charge.

We recommend starting with the Free 1900 Foil Wing set on the 66 or 74 aluminum fuselage and 260 tail wing if this is for e-foiling!

2.) Assist Aluminum - Assisted foiling

Take your foiling to the next level with the 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 Set

Built 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 minimize 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.

3.) Assist D/lab Assisted Foiling

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.
