As I've written in previous post, " these context, in air or in water, an HIGHER Aspect Ratio has pratical effect of increasing LIFT (above all when angle of attack increases)..."

And when a windsurfing board runs on water it always (and inevitably) assumes a certain Angle of Attack for board design (scoop line).
