The precisely-crafted Mast section profile is constructed from aeronautical grade 6061-T6 Anodised Aluminium, with a well-balanced strength to weight ratio.

- 70cm Mast
FEATURES
Strong and light
The aluminium Mast's section profile reflects an optimised balance for strength to weight ratio.
GeoLock
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. Screws engage the GeoLock while load transfer now takes place over the full cross-section of the mast profile, allowing for a more efficient load transfer and longer-lasting connection.
Board Adaptor
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.
