The A700 fuselage and AF72 Mast combine to create a stable, controllable foil system that can be matched with any front wing, so you can learn to wing, SUP, surf and kite foil with confidence. The forgiving longer fuselage delays the pitching moment, giving you greater time to react. It’s precisely CNC-machined and hydrodynamically optimised shape offers minimal resistance, while the aluminium mast delivers the best balance between light weight and increased strength for higher loads. The AF72 mast is also ideal for shallower waters and prone surf foiling. Simply choose the Sonar Front Wing best suited to your needs to complete your setup (Sonar Front Wings, Foil Board and foil to board attachment hardware sold separately)
Cruise control. Forgiving 700mm long fuselage 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.
Foil to board mounting screws are supplied with North Foil Boards
Sonar Foil Board Adaptor
New Board Adaptor for the AF72 and AF85 masts. FE-Analysis allows us to optimise the structure, increase strength in the areas of highest stress concentration and reduce unecessary weight in lower stress areas. 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
The Sonar Foil System can be mounted to any foil board with a 165x90mm bolt pattern. Foil Board and foil to board attachment screws sold separately
Supplied with Sonar Travel Bag
Stow your Sonar Quiver safely in between sessions with our Heavy Duty 600D Padded Travel Bag. Roomy enough inside to fit the complete Sonar Foil set, including all three wings and three masts inside their individual covers. 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 worry-free travel companion. Included with every complete Foil Edition.
Modular foil system
Customise your ride with our fully interchangeable foil parts to explore multiple disciplines and riding styles all with one setup.

Sonar AF72 Mast
New refined aluminium foil section gives the best balance between light weight and increased strength for higher loads. 30% stiffer than the AK mast yet only 13% heavier, the AF72 mast is ideal for shallower waters, and prone surf foiling.
Easy recovery from surface breaching
In perfect harmony with any Front Wing, our dihedral-shaped carbon pre-preg rear Stabilizer provides control and riding comfort, allowing fast pivoting turns and easy surface breach-recovery. 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.
Includes: AF72 Mast, AF Board Adaptor, A700 Fuselage, S01 Stabilizer, Tool Kit, Screw Packs A,B,C,* Travel Bag.
