Wouter, <br>My personal view .for what it's worth. Length times thickness as opposed to wetted surface. But it is very possible that I'm wrong as I've never really analysed the situation. <br>Most Taipan sailors leave their boards down on all points of sail. They say they can get away with this because they are so thin (ie depth of chord not length of chord).and the drag is so low that its not worth pulling them up even when they have to sail flat. <br><br><br>
I know that the voices in my head aint real, but they have some pretty good ideas. There is no such thing as a quick fix and I've never had free lunch!
