Dial in your foil with small, repeatable adjustments — positive and negative shims in one set, so you can fine-tune stabilizer angle and overall pitch feel.

The Unifoil .5 Degree Shim Set gives you precise, repeatable control over how your foil rides. Add lift for earlier takeoff and a slower stall, or take it away for more speed and a flatter, locked-in feel. Small changes — big difference on the water.

Positive and negative. One set.

Red (positive) shims — add lift and earlier takeoff, with a slower stall speed. The go-to for getting up sooner and holding through slower sections.

White (negative) shims — reduce lift for more speed, a flatter trim, and calmer pitch. Ideal when you want a more locked-in, high-speed ride.

What's included

  • Red (positive): 0, +0.5, +1, +1.5, +2, +2.5, +3
  • White (negative): −0.5, −1, −1.5

How to use

Want more lift / earlier start / slower stall? — add a positive shim.

Want more speed / less lift / calmer pitch? — add a negative shim.

Make one change at a time — adjust in single increments until it clicks.

Pro tip: note your favorite shim per board and discipline. Once a setting "clicks," you can return to it every session for a consistent, repeatable ride.
