I totally agree with the TheMightyHobie18 being over built. We had one in the early 90's w/magnum wings and that thing was a tank. It was great through the chop.
I would venture to say that the Hobie 18 is as close as you will get to a pitch-pole proof cat. It can be done, but you really have to be careless. Good boat, just too bulky for my taste. In a good blow it will make you think twice about wanting to sheet in harder.
