So... he's saying that the sails themselves are generating lift, but since they are also pulling the boat forward from so far above it, they are "pushing the bows down" (because they are, in effect "tripping" over the bows").

This is why lighter crews have less tendancy to pitchpole? Because the entire boat has less weight and is therefore more easily driven (or accellerated) by the sails?

Sounds good to me, I only weigh 145lbs and I usually sail solo! I guess that means I'm just more likely to capsize than to pitchpole

Why don't we settle this once and for all. Someone give me a spinnaker pole, a spinnaker, and a hooter. I'll go sailing as much as I can for a year and get back to you with the results
