Foil Drive Assist Slim

The Assist Slim is the lightest, performance-focused model designed to preserve the weightless and natural feel of foiling while still providing plenty of thrust and runtime when used efficiently.

Built for riders who prioritise responsiveness, agility, pumping, and minimal drag, the Slim excels in short, powerful bursts to get on foil before transitioning to pure glide. It offers the same peak power as the Assist MAX in a thinner, more compact system. Ideal for experienced riders who value balance, light weight, and reactive carving in surf, wake, windswell, and flatwater.
