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

Tech Features
Stiff mast for a direct response
The eMast AL Cruise is incredibly stiff and provides a direct, responsive feel.
Low drag through integrated motor pod
The fully integrated motor pod, positioned 15 cm above the fuselage, and internally routed cables optimize glide and maneuverability while allowing for easy assembly.
Propeller guard
The optional propeller guard attaches to the motor with three screws and provides protection from the rotating propeller. Caution is still advised.
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 Cruise Mast AL can be mounted to any brand’s foilboard with standard US foil tracks.
Reliable signal transmission
The wireless 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.
