Our new refined aluminium foil section gives the best balance between light weight and increased strength for higher loads. The AF72 Mast is 30% stiffer than the AK70 mast yet only 13% heavier, and is ideal for shallower waters, and prone surf foiling. The AF85 Mast is 30% stiffer than the AK85 mast yet only 13% heavier, and it increases overall ride performance in choppy conditions. AF Masts are only compatible with the AF Board Adaptor (sold separately). AF Masts are NOT compatible with the AK Board Adaptor.
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.
All Sonar Foil Editions come complete with the correct Board Adaptor. Additional AF Masts for AF Editions do not require a new board adaptor. To upgrade a Sonar AK Kite Edition for wing, surf or SUP foiling, you will need to purchase an AF Board Adaptor with your AF
The aluminium mast's section profile reflects an optimised balance for strength to weight ratio.
