A whole lot of variables in that test.No waves ,no current, no wind,Boats have to weigh the exact same and the tow rope has to be spot on dead center.

The flat bottom, square edge thing might work great, until the boat heels. I seriously doubt naval architects have been doing it that wrong all this time.

If a man is to be obsessed by something.... I suppose a boat is as good as anything... perhaps a bit better than most.
