Pitchpoling was an issue with some of the early narrower cats, I think you will find this is not an issue with modern designs as designers have taken the problem to heart in their designs.
I know he is sailing Hobie's but I asked him for his experience and he gave some insights that probably do translate to a bigger class.
He mentioned that the minimum weight in still waters to bring the cat up is a 3rd of the boats top weight which the crew must equal unless they need external assistance. He also mentioned the issue of righting which can cause the cat to mediately capsize
again due to the inertia caused by acceleration of the top side mass.
He also mentioned technique which with respect to leverage which would also apply in similar fashion but of course be done mechanically.
Interestingly I also spoke to an insider today that tells me that ISO are looking to impose a need for cat certification
to stay at 90 for a certain time up to mid size so clearly the problem is being addressed and is regarded as one. I have also been told there are some clever minds behind the scenes working on workable solutions to this problem.
However, I imagine the standard will require a time delay before total inversion based on a test in a mill pond and I think it is aimed at the charter
sector to give people a chance to evacuate properly rather than to bring the boat back up never the less it is a step in the right direction.
Leave it to the Brits.. We will sort it out for yer.
