From: "Michael Edelman" <mje_at_spamcop.net> > How about, "when a boat displaces significantly less water than > its actual weight". Of course, then we need to figure out what > "significantly" means.... This is exactly what is measured when we see the CG rise. In very general terms, semi-planing is when the boat is displacing less than the maximum and planing is when it reaches maximum. Trim changes as well and the nature of resistance changes from wave and skin friction dominated to spray and skin friction dominated. None of this defines planing, but describes its behavior. But remember, the real issue is not what planing is, but what the difference between planing and surfing is. I think most folks can accept the definition of planing. They've been talking around it for a while.
