I have managed to locate the 'Moses' quote by Bob Perry that I referred to earlier:
"I have never bought into the often heard Moses theory that the pointed stern 'parts the waves'. For safety
in heavy weather
running, I would prefer to see a stern with more bouyancy aft and that's why I used the tumblehome canoe stern as seen on the Valiant yachts. With this shape the volume is pulled as far aft as possible before pinching it together. Certainly bringing the ends together can produce a 'balanced' set of waterlines that may enhance a boat's helm
I've designed sterns that have ' the shape you love to pat' myself, but I've put those sterns on boats whose sections were full right aft. It is an aesthetic thing, yes, but I make no claims that it makes a boat safer in heavy seaways."
