Ideal for wing, surf and SUP foiling


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.

GeoLock optimised load bearing connection

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.

Sonar Foil Board Adaptor sold seperately

All Sonar Foil Editions come complete with Board Adaptor. Additional AF Masts for AF Editions do not require a new board adaptor. To upgrade the Sonar Kite Edition for wing, surf or SUP foiling, simply purchase an AF Board Adaptor with your AF mast.

Compatible with carbon and alloy fuselage

Hydrodynamically-optimized shape for minimum resistance, the Sonar Alloy Fuselage is precisely CNC-machined 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.
