[quote=traphappy]I just started sailing a Nacra I20 and am curious to what extent do bottom and daggerboard imperfections affect speed for the recreational sailor. I have a couple of long indentations on the hull bottom from the previous owner sliding the boat over a rock and recently repainted one of the boards, leaving minor brush marks in the finish. What seems to limit speed the most is the boat becoming overpowered, even when double trapped. I was wondering if a better bottom would translate into more power being converted to speed. I suspect that the answer he is going to be that imperfections slow the boat but only enough to notice over the course of a two hour race.
