AOA – Angle of Attack

In general the performance effects of using negative degree shims to reduce the AOA are:

 • Increased top end speed and glide performance

• Front foot pressure decreased, back foot pressure increased

• Decreased pitch stability

The higher the degree value, the greater the effects will be. We recommend starting with the -0.5deg shim, then decreasing the AOA progressively with the -1deg and then -1.5deg to feel the effects and find your preferred setting. 

Entry level to intermediate riders – if you feel too much front foot pressure, before fitting a shim to adjust the rear wing AOA, we recommend first adjusting the position of your foil on the board by moving the mast backwards. This will reduce front foot pressure without deceasing stability of the foil.
