I’m sure the boat companies have researched this to no end but while watching F1 this morning I was thinking about aerodynamics and my thoughts went to hydrodynamics and boats. It seems that all the research and tuning is in the hull running surface and the skegs and rudders have always been the same. It seems that handling on boats could be improved with a new design of skegs and rudders without affecting wake size. I know nothing about this, I just thought it was interesting.
