2021 North Sonar Foil Mast
Description :The aluminium mast's section profile reflects an optimised balance for strength to weight ratio.
Our new refined aluminium foil section gives the best balance between light weight and increased strength for higher loads. The AF72 Mast is 30% stiffer than the AK70 mast yet only 13% heavier, and is ideal for shallower waters, and prone surf foiling. The AF85 Mast is 30% stiffer than the AK85 mast yet only 13% heavier, and it increases overall ride performance in choppy conditions.
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.
Hydrodynamically-optimized shape for minimum resistance, the Sonar Alloy Fuselage is precisely CNC-machined from 6061-T6 aeronautical-grade anodised aluminium with structurally engineered connection details that are designed to last. Our new high-strength pre-preg carbon fuselage is strong, durable and corrosion resistant, and weighs ~50% less than the alloy version, with equal strength and stiffness. The shorter 600mm Fuselage improves pumpability and has a sporty feel with earlier take-offs. The forgiving longer 700mm fuselage is ideal for wing-foiling or learning to foil, offering greater stability and more control.
