Re: Would like some more info.
I would not pigeon hole yourself into one particular brand. Expect to get a qualified inspector for any boat that age. Also expect there to be issues with boats 30+ years old, not trying to scare you.
Ok, but Catalina isn't a bad choice for a starter boat, mostly because they carry nearly all the spare parts at catalinadirect.com
But there are so many heavier boats, more popular boats, at that age I'd submit that you should keep your options open. I mean if a great C&C shows up in your price range, and it inspects well, go for it.
When they say give as much information, they are looking for what your intended use will be. Seems like your focus is on space down below. Are you planning on living aboard? If so we can refocus our recommendations on 27-32 footers with large living space.
Hull #68 S2 7.9 on our little landlocked puddle, Lake Wallenpaupack, PA, it's cheap, trailerable, and paid for.
