Despite the fact that this guy obviously has no class or sense of taste, he in fact correct about the effect of the VDH hull when sliding down the face of a wave in a beam sea. It will roll faster than a boat with a flat hard-chine system.
BUT THAT'S NOT THE POINT. The only reason I'm ever gonna be "sliding" down the face of a wave in a beam sea in my Seacraft is if I tilted my engine out of the water, and lose my sea-anchor and both regular anchors, and then lose my raincoat, and my baitbuckets, and anything else I can make an impromptu sea anchor with. And all this while coming in Jupiter Inlet on an outgoing tide during a Nor-Easter in November.
Even then, I stand a MUCH greater chance of foundering from being pooped than rolling over in a beam sea.
So, while this guy is technically correct in that one statement, he's obviously no seaman.
