My experience with the Wave is very limited, but not in sailing in general. I was basing my comments on the posts I have read here, and on the one day I have been able to sail in strong winds. The boat did not PP but the lee hull did try to bury itself and many times was fully under water going through waves. Having read the posts I had put myself as far back and outside as possible and that may have been the difference.
I love the boat, love that I can truck top it with my camper on the back and still take both my kids out to sail and have a fast fun cat to sail solo when the wind picks up.
Anyway here is the link to the photos from 2003 nathionals showing a PP in action. http://www.catsailor.com/waves/WaveNtls03.htm
Just scroll down a little and there are three photos in sequence of a boat going nose first.
