Quite a discussion on SA about the new A class. One of the posters states square edges cause too much drag.
I've always heard flat bottoms (I'm assuming square edges) are faster. Is there any PROOF one way or the other?
We might as well start a discussion about wax vs. wet sanded hulls. It's hard ($) to put any real science behind it...it's really difficult to simulate the real world situations the cats go through and get any real discernible data.
