In four years of sailing my P16, I have only dumped it twice....both times the result of a pitch pole while driving the boat in heavy wind.
When under those conditions, I make sure the main sheet is not cleated. Letting it run quickly dumps the excess wind. The bows rebound and it will settle back down.....off to screaming toward the beaches again.
My first time caught my crew by surprise. He lost his footing and did a Peter Pan on the wire. One thing about being attached to the top of the mast, if the crew goes over, they tend to pull the mast with them. I slid across the tramp into the water as the wind finished the process off.
The pitch pole seems to be a recoverable process as long as everyone is ready to adjust in a seconds notice. In heavy wind, I now find my crew behind me straddling the rear cross bar with a horse collar grip around my PFD so he doesn't perform any more magical flying acts.
