asymmetrische vinnen
The science behind an asymetrical fin is the same as an airplanes wing, it is designed to generate lift by producing a low pressure "pocket" on the curved face. On a plane this creates lift, on a board it helps track upwind a little easier, this only works efficiently if the fins are spaced far enough away from each other, if they are both fully inserted in the water they will counteract each other and actually reduce hydro-dynamic efficiency, this means that they work better when the board is being edged. This also results in better grip given the angle of the board in the water when edging, it "pulls" the board into the water on the edge.
OK?
