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.
FE-Analysis allows us to 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.
Compatible with AF foil mast series
The AF Board Adaptor is designed specifically for use with our higher load AF Series masts. It is not compatible with the AK Mast Series.
