The Foil Drive Assist MAX+ takes everything that the world loved about our most popular foil assist and evolves it into the latest Gen 2.5 class, turning up thrust, runtime, and safety features to unlock autonomy across all foiling disciplines.

Built around the same proven 43V power, tech, and charging architecture of the Fusion, the MAX+ offers our most durable one piece battery design, all while retaining the compact, lightweight and balanced package that made the original MAX so versatile.

Unlock smaller foils, boards, performance, faster take-off, and more time on the water with tilt-safety cut off features that makes this same retrofit kit so family friendly.

The lightweight balance that made MAX the all rounder remains, while everything around it has evolved.

Riders can enjoy a sportier feel without compromising on thrust and boost thanks to the NEW FM+650 Battery (650Wh) and early in 2027 the even smaller, FM+430 Battery.
