North | Foil Drive

The Boost and UHM80 FDA18 Integrated Carbon Mast are shaped to get up on foil fast and stay there, so your sessions last longer. The board’s drag-reducing super trench is sized for quick battery swaps without removing the Foil Drive, and compatible with the Slim, Max and new Fusion system.

We’ve teamed up with Foil Drive, the inventors of the electric Foil Assist, to integrate Foil Drive technology into our Sonar UHM80 and AF80 Masts for electric assistance hydrofoiling with minimal drag, improved ride feel, and enhanced efficiency.

The Foil Drive Masts have a Motor Pod pre-installed at one of four positions. The FDE-Foil’s is near the fuselage. The FDA20, FDA18 and FDA15 bring the motor closer to the board for assisted foiling – the motor provides speed to lift onto foil, and when it exits the water, your foil takes over...

Purchase your Sonar FD Integrated Mast pre-assembled with a Foil Drive Motor from a Foil Drive retailer, and complete your assisted foiling setup with a Sonar Front Wing / Fuse / Stab. We recommend the SF Series, MAv2 Series and DW Series Front Wings.
