If one puts a couple of surfer boards then they will have Frank Bethwaite's high speed craft. But the principle in this craft is exactly what Frank did in the umm 70 or 80s?

For what its worth the boat, I suspect, is designed to sail flat like a needle hull 18teen. <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
