It looks like the Bristol 34 has a lot of teak warmth in the interior, a Catalina 30 might pass you, but do you care? The Catalina 30 sails fairly well, but feels very antiseptic to me; I like that wood warmth feel, too. I've never been on a Bristol 34 (or a Tartan 30), but maybe the other key, besides feel, is just how good shape they are in. These are old boats, and Summer is too short to spend on boat "projects".
The Bristol 34 design looks interesting... Good luck! cheers
