Adjusting your foil in a double US rail

The placement of the foil in the US double box is super important! When new material is discovered, logic dictates that it should be balanced. It is therefore necessary to start with an adjustment centered in the middle of the box and to adjust its adjustment according to the following criteria:

  • Its size
  • Its target
  • The conditions

Foil in front of the rail

The more advanced the foil, the more power it will offer.

A bigger boat will compensate by moving its foil forward in the boxes.
In the low rpm, under sail, soft waves, low speed, you can move the foil forward to get more lift.

Foil behind the rail

If the foil is ejecting and forces you to press too hard on the front leg (lighter weight, high speed, stronger wind…) you have to move the foil back in the boxes to get more control by reducing its power.

It is also possible to play on the dynamic behavior of its foil. We can make the foil more powerful by using a wedge to kick its stab and compensate by moving the foil back to control it. This can bring pumping or energy in the jumps!
A rather forward foil will offer a lot of maneuverability.
Combined with a stab kick, it optimizes the reactivity in the low revs.

In foil, the game of adjustments is almost endless. It’s all about finding the right one for each individual and the conditions of the day. There is no single setting!
