Interesting article. All sorts of variables involved. (couldn't see the pictures) I was mainly presenting the idea that the bow on an upright boat would more easily pierce waves than a boat that was getting slapped along the flattish expanse of its forward topside. (Except for scows) Conversely, I suppose that an increased flat area astern could help a boat to surf more easily.
But, I'm mainly a river rat; a brown water sailor. Saw a 2-footer once. :-) Bob M Ox 33-1 Jax, FL On Thu, May 23, 2013 at 6:27 PM, Dennis C. <capt...@yahoo.com> wrote: > Not necessarily true.
