Key Features.

modular foil system.

Customise your ride with our fully interchangeable foil components to explore multiple disciplines and riding styles all with one setup. Start building your quiver here. Seamlessly compatible with any North fuselage, stabilizer, mast or front wing.

Sonar AF72 or AF85 Mast

The AF85 mast performs across all disciplines and offers you more ride height to clear waves or to heel over for tighter turns. It is also more forgiving in rougher conditions. The AF72 mast is ideal for shallower waters, and prone surf foiling. Optional 55cm AF mast also available for extremely shallow locations.

GeoLock Load Bearing Connection

Screws engage the GeoLock while the load transfer now takes place over the full cross-section of the mast profile, allowing for a more efficient load distribution and longer-lasting connection.

New S270 Carbon Stabilizer

The Stabilizer’s positioning on top of the Fuselage allows for a clean, undisturbed approaching flow. Surface piercing of the Stabilizer is not a problem, as the Front Wing sits deeper in the water and is still fully submerged, giving you that extra time to react and adjust your ride height. Pair with the Stabilizer Shim Kit for even greater customisation of your ride.

Sonar AF Foil Board Adaptor

Incorporates a strong geometry locking connection for better energy transfer and a more direct feel. (Not compatible with AK Mast Series)

Industry-standard 165x90mm bolt pattern

A measurement guide next to the track aids correct positioning. Your Sonar Foil can also be mounted to any foilboard with an industry-standard 165x90mm bolt pattern. Board and foil to board attachment screws are sold separately.

NEW 700mm Fuselage

It’s forgiving 700mm length improves stability when paired with any wing. Ideal for learning to foil, the longer fuselage delays the pitching moment, giving you more time to react. It’s precisely CNC-machined and hydrodynamically-optimized shape offers minimum resistance and features GeoLock. Fits all Sonar Masts.

Supplied with Sonar Travel Bag

The bag also has enough depth to leave the Board Adaptor connected to the mast, making your foil packdown faster. Designed with straps, clips and interior pockets to secure contents. Your travel-friendly companion. Included with every complete Foil Edition.
