WING / SUP / SURF FOILING
The new refined aluminium foil section gives the best balance between light weight and increased strength for higher loads, so you can wing, SUP, surf and kite foil with confidence, making use of the fully interchangeable Sonar Foil System to extend your playtime on the water. Engineered to last, with exceptional strength to weight ratio, and our unique GeoLock system for a clean, direct feel with minimum resistance on the water. The AF72 mast is ideal for shallower waters, and prone surf foiling. The AF85 mast increases overall ride performance in choppy conditions.
Package includes:
- AF85 cm Mast
- Foil Board Adaptor
- A600 Fuselage
- S01 Stabilizer with cover
- Tool Kit
- Screw Pack
- Mast Cover
- Travel Bag
- (Foil to board mounting screws are included with North Foil Boards)
Highlights:
- Sonar CF72 or CF85 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.
- GeoLock Load Bearing Connection: Engineered to last, our unique GeoLock tapered geometry locking system provides a more effective load-bearing connection between the Mast and Fuselage. Screws engage the GeoLock so the load transfer takes place over
- 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.
Features:
- Sonar af 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 separatel
- Fuselage 600mm: 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.
