Re: Maximum hull speeds ?
IMHO, the reason a sailing hull tends to bury the bow is because the centre of thrust is above the waterline and the centre of drag is below, so there's a turning force trying to trip the boat over the bow. It's like the heeling moment heeling on a reach. With one of those free-flying kites set high and well forward, the force would still be there, but largely counteracted by the lift from the kite.
It's possible to exceed hull speed significantly under sail without planing. It's just a matter of power. I've read something about a Warrior 35 caught in a squall doing 15kts, and I'll take a lot of convincing that that hull was planing! (Almost as much as it would take to get me on board if someone offered me a chance to experience it - it must have been a real brown trouser moment! [img]/forums/images/graemlins/tongue.gif[/img])
Never believe anything until it has been officially denied.
