North Sonar 40cm Foil Mast 2020
North's 40cm School Mast, for those first-time feels, is an ultra-forgiving Mast height suitable for skimming just above the water and easy recovery.
The precisely-crafted mast section profile is constructed from aeronautical grade 6061-T6 Anodised Aluminium, with a well-balanced strength to weight ratio.
- 40cm Mast
Strong and light
The aluminium Mast's section profile reflects an optimised balance for strength to weight ratio.
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.
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.
