The shims can be used to adjust the angle of attack of the back wing to turn that lift-off behavior, speed, and turning.
Most hydrofoils in the market are set to a single AOA (angle of attack) at the back wing, usually varying between one- and three degrees. The Airwave is different, as it comes with three precision tuning shims, allowing the rider to adjust the AOA of the back wing to customize the balance between lift, speed, stability, and turning.
Three anodize aluminum shims allow you to trim your foil for different water conditions. Available in 1,2, and 3 degrees.
Switching to the 1° shim (silver) gives less lift.
making it the one with the most speed potential of your tuning shims.
consider it the baseline we design all our foils to and you are the best place to start with. Like in regular surfing, each shim has its own feel and performance characteristics. Since a hydrofoil moves on three axes, instead of the conventional two, we recommend you experiment as your skills develop.
but at higher it generates a serious amount of lift, requiring you to continuously counteract by applying front foot pressure. Needless to say, all that lift also generates more drag.
3D-printed 2° shim
The Airwave can be used with the optional 85 Fuselage which is perfect for foilers wanting to go wind- and kitesurfing. This extra long fuselage is supplied with a unique and neutral 3D-printed shim.
The 85 fuselage will accommodate the standard supplied shims as well, but they are a little narrow, as the Fuselage 85 tip (tail) is a fraction wider.
