Sonar Foil Technology
SONAR AF72 OR AF85 MAST
The 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. 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.
Engineered to last, our unique GeoLock tapered geometry locking system provides a more effective load-bearing connection between the Mast and Fuselage, locking them together, so they feel like one piece. 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.
Hydrodynamic Carbon stabilizer
In perfect harmony with any Front Wing, our dihedral-shaped 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.
The Sonar Foil System is connected to the board by a lightweight CNC-machined aluminium Board Adaptor with a tapered geometry locking connection that engages with the mast. Fusing Board Adaptor and mast together to build one union for optimum load transfer and a stronger, more direct feeling and steering impulse when foiling.
165x90mm Bolt Pattern
The Sonar Foil System can be mounted to any foil board with a 165x90mm bolt pattern.
CNC-machined anodised aeronautical grade 6061-T6 aluminum Fuselage. Hydrodynamically optimised shape for minimum resistance.
Modular Foil System
Customise your ride with our fully interchangeable foil parts to explore multiple disciplines and riding styles all with one setup.
