Which outline gives the least drag? Many big light wind boards have and s-shape, so that they become narrower right at the middle of the board. I can see that there is less surface in the water, which equals less pressure on the board. And therefor less drag?? Or what?
And the big light winds boards are often ridden more flat and not edged. Is that why the s-shaped outline works for light wind boards?
I guess my question is, would a s-shaped board in smaller sizes (135x40) get any advantages? Low end maybe? And what would the compromise be?
This is what I mean by s-shaped. The board to the right gets more narrow in the middle.
