Foil Drive Assist Slim (Base Kit)

FD103/FD128-1

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.

Note: This is a Base Kit ONLY, no motor or battery included:

Built for riders who prioritize 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.

Why a Base Kit?

1. Purchasing an Integrated Mast - The base kit does not include a motor allowing you to not double up when you buy your mast!

2. You're upgrading or adding to your fleet - If you already own Slim batteries and motors, but simply want to add another system to get another board set up, this is a great option!

3. Full Customization - The base kit provides a great base to build out your kit yourself
