Use the drop-down menu to order online which battery size you would like and we will contact you to discuss the best cable length for you and the brand of mast you want to use it on.

The Foil Drive Assist Slim is the smaller, lighter, performance-orientated model, for the ultimate in performance hybrid electric assist foiling. Despite its small size, it offers plenty of thrust to get you of foil easier and sooner however the smaller batteries do reduce the run time. The Assist Slim is perfect for advanced, high-performance riders or wingers/downwinders that do not require lots of battery capacity.

The kit includes everything you need to turn your existing foil and board into an electric-assisted foiling machine! 

Simply choose your desired:

• Gen 2 Slim Battery
• Gen2 Motor Height
• Mast Adaptor to suit your exact foil mast of choice.

If you are looking for an integrated mast with your Assist MAX see:

• Assist MAX x Project Cedrus Integrated Mast which we have listed separately
• Assist MAX x AXIS Integrated Mast which we have listed separately

The Foil Drive Assist Slim is perfectly suited to those just looking for an extra boost to get on foil or to ride smaller boards and foils. The Assist Slim is not suitable for prolongated periods of motor assisted riding, it simply provides the boost to get up on foil and ride more. Advanced Surf and Downwind riders will love the low profile and weight but will need to be very disciplined on the throttle usage. Wing foilers simple do not need the run time usually and will also appreciate the low profile and weight.
