Windfoil chock, what is it for ?

Find our complete guide to start windfoiling.

Wedges are now part of your foil quiver. There are two possibilities for their use:

  • Adjustment of the float trim
  • Constant support setting


Trim the float with a windfoil wedge

The first adjustment that the windfoil can make is the position of the float attitude in flight. A float that is nose down is a float that will have its nose diving forward. A float that is nose up, is a float that will see the nose rather up. In these cases, a wedge at the front of the wing or at the back of the wing will optimize the overall attitude during flight. If I put a wedge at the front, it will lower the leading edge of the wing which, when flying, will get back in its line. So with this movement, we can understand, that it is the nose of the board that will rise. Conversely, a wedge at the back of the front wing on a windfoil will return to its line and the nose of the board will drop.


Constant pressure adjustment with a windfoil wedge

Adding a wedge to the stabilizer will intervene when there is a constant support problem, i.e., my board constantly wants to get out of the water. So we have a problem of overpowering the stabilizer. At this point, a wedge should be placed at the back of the stabilizer. We’ll release the stabilizer to give it a slightly more negative impact and rebalance the phenomenon. Conversely, you can have a foil that is very backward. That is to say that it flies but I have to lean a lot on my back leg. At this point, we will place a wedge at the front of the stabilizer. We will put some kick and this phenomenon will give an influence of lift.



So to conclude:

  • The addition of a wedge at the stabilizer is really when you have a constant movement up or down
  • The addition of a wedge on the front wing is interesting when you have a discomfort due to a given position too low or high.
