The point is to stay on top of the wave as you have to make the speed from the wave. If you move away from the wave and you don’t have power in the sail then you lose the speed. So you just have to stay close to the wave. I have used a few different setups but in the lightest conditions I am on my 86 litre and 5.0m sail. You have to stay high on the wave, that is the key!
