Foil Drive Assist Slim | NORTH Sonar AF80 Integrated Mast

The Assist Slim is the lightest, performance-oriented model, designed to preserve the natural, weightless feel of foil while delivering sufficient thrust and range when used efficiently. It excels at short, powerful take-offs to get on foil before transition, with minimal drag, agility, and excellent response.

This pack combines the Assist Slim system with the North AF80 integrated mast in aluminum, with the motor pre-installed inside the mast. With the cable integrated inside the mast, assembly is cleaner, drag is reduced, and you gain torque at low RPM for easier take-offs and longer sessions. Configure your options below.
