If you want something more comfortable in the chop you need a bigger boat, not a different 30' boat. In a gale they all seem to shrink like a cheap T-shirt anyway.
Adventura in Dana just started chartering a 2002 Bene 323, rent it for an afternoon, that should sell her ASAP, and answer your questions. However, there's probably no retreating once she gets a taste of some comfort. Don't even let her see a boat with ultra leather upholstery and innerspring mattresses if you don't want them on the "must have" list.
