Understanding front wing sizes

“I designed our foil wings naming them S M L XL etc … so that everyone can easily find their way around.

You have to see it as follows : after progressing on a Curve L, you might want to evolve on a Fluid for example. Well, the size you need for the Fluid would be L again.
Indeed, it’s the change of program that is judged: you go from a versatile and easy surfer wing, to a faster and very manoeuvrable wing. But your weight remains the same, so does your spot, and the wind range in which you use it too.

The right size for you in one model is therefore the size that is right for you in all GONG models.

That being said, you probably also want a light wind or a strong wind front wing. The variation in available power will require you to adjust the size of the wing of your foil. (It is not an absolute requirement by the way.) In this case, you want another size, M or XL for example.

But remember that I have scaled all the wings on a single equivalence grid. An L is an L.

You will tell me yes but the Fluid L is much smaller than the X-Over L !!! It’s true and that’s precisely my job: to estimate exactly your progress when you decide to switch from one to the other and to calibrate the sizes so that you feel like in slippers with your new wing in a new program. You go from an athletic beginner to a radical carver, it is logical that the necessary surface for your performances will drop considerably. And I am the one doing the math to adjust the ranges. ” L’Ours.

Which stabs?

The stabs have a major role. They determine the stability of the foil and help the lift, but at the expense of the maximum speed of the foil.

Thus, thick stabs are slower than thin stabs, but are much more load-bearing, and therefore effective at low speed. Rectangular stabs are more stable than stabs with fine points.
