Like the Formula..
You are right, its not that far off (closer than I`d imagined)but far enough to produce significant differences in power /stability especially at sail`s limits.
Seems a shame that we cant rely on measurements when we are involved in a sport with many things that cant be quantified..
Volumes/Weights/Sail area / mast stiffness and others all seem to produce anomolies... Things which in industry would be specific and measured accurately..
As customers we just accept it ???
Might just buy the Ezzy`s ???!!!
