good pitchpole recovery here from 18 secs
http://au.youtube.com/watch?v=EYsF-wtdjEEi'd say it didn't complete the pitchpole, or then go over sideways, due to 3 things
1). it's an old nacra 5.2 with lots of bow volume, really important, and lipless decks, not quite as important but still helps "pop-back" instead of "dig-in" when the hulls are at 45degrees. no coincidence that pretty much all new cat designs look very similar to tom rolland's 32 year old design
2. with 1 guy firmly planted on the tramp when it does dig in he doesn't go flying forward of the main beam. that's really important as 75kg suddenly going from the back half of the boat to the front means 150kg change in pitching moment. almost guaranteed to drag the mast too far forward and over. AND staying on the windward hull also prevents the sideways tip-over that often happens after a half pitchpole when 1 of the crew's weight is suddenly off the windward hull
3. the helm stays on the wire the whole way through without getting forward of the mainbeam. skill, luck or lots of grippy hull tape? whatever, it works
