North Aluminium AF

Our refined aluminium foil (AF) section gives the best balance between light weight and increased strength for higher loads. The AF72 Mast is ideal for shallower waters and prone surf foiling. The AF80 is the perfect beginner size for wing foiling. The AF85 performs across all disciplines and is more forgiving in rougher conditions. The AF85 and AF95 offer you more ride height to clear waves or heel-over for tighter turns. The 55cm AF mast is for extremely shallow locations.
The Sonar Mast features our unique GeoLock tapered geometry locking system. Engineered for strength and stiffness, GeoLock 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, enabling the load transfer to take place over the full cross-section of the mast profile, allowing for a more efficient load distribution and secure connection that is made to last.
NOTE: The AF Mast does not have an integrated foilboard mounting plate. To mount to your foilboard, you will require the AF Board Adaptor, sold separately or included with all Sonar AF and Prime Editions.
