Board adaptor, collar, base plate, whatever you want to call it, this is it for the North Sonar AF (Alloy Foil) Masts to attach to any standard 90mm foilboard track system.

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 astronger, more direct feeling and steering impulse when foiling. FE-Analysis allows us to increase strength in the areas of highest stress concentration and reduce unnecessary weight in lower stress areas. Incorporates a strong geometry locking connection for better energy transfer and a more direct feel.
