last year our friend's son and his friend had a h16 hull fail and the catamaran was 95% underwater.... i wouldn't call that sunk, but it surely wasn't afloat either
It takes 10 adults to sink a H16 to the point that it is unsailable. So two big guys could blast around the bay in blustery weather or one guy would be able to sail solo and right it alone.
this was a sound boat loaded with people and beer.
H16s will pitchpole but that's part of the fun. If you don't pitchpole once in awhile you aren't pushing hard enough. My most radical pitchpole left a purple stripe from my ankle to my arm pit that lasted for weeks. First aid required an extra beer or three...
