North Sonar Mast 70

Surf MastChoose

the 70cm mast for prone foil surfing in waves. The 70cm is also an ideal height for learning to kitefoil. and for freeride foiling in shallow waters.

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

FEATURESStrong

and lightThe aluminium mast’s section profile reflects an optimised balance for strength to weight ratio.

GeoLockEngineered 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 AdaptorThe Sonar Foil System is connected to the board by a lightweight CNC-machined aluminum 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.
