Key Features & Benefits

Ultra-Low Drag, Seamless Integration
The fully integrated motor pod—positioned 17 cm below the top plate—combined with internally routed cables delivers a clean, streamlined profile. The result? Smoother glide, improved maneuverability, and easy assembly with minimal resistance in the water.

Stiff Alloy Mast for Instant Response
Built with a rigid, surf-inspired alloy profile, the mast offers direct power transfer and precise control. Expect faster reactions, reduced flex, and an incredibly smooth, efficient ride—even at higher speeds.

Highly Modular, Brand-Agnostic Compatibility
The Foil Assist Alloy Mast is designed to grow with your setup. Swap motors and connector cables effortlessly across the Foil Assist mast range using the quick-swap adapter system. It’s compatible with fuselages from nearly all major foil brands, including Duotone, F-One, Armstrong, Gong, Axis, Lift, North, Code, Sabfoil, AFS, and KT, and mounts to any prone or wing board with standard US foil tracks.

Unmatched Thrust for Faster Takeoffs
Powered by a high-torque motor delivering up to 33 kg of thrust, this system gets you on foil earlier than ever. Ride smaller foils and boards with confidence while gaining sharper responsiveness, tighter turns, and better overall control.

Folding Propeller = Low Drag & Added Safety
The folding gear propeller only opens when the motor is engaged, keeping drag to an absolute minimum when gliding. It also enhances safety during wipeouts. Want even more punch? Upgrade to aluminum power propeller blades for added torque.

Reliable Power & Rock-Solid Signal
With the receiver housed directly in the battery box on the harness, signal transmission stays strong and consistent. The result is dependable propulsion and precise control throughout your entire session.
