My Yankee 30 and a Catalina 30 (for example), are two very different boats. While a foot more beam in the Catalina doesn't seem like much on paper, the actual difference down below is startling. On the other hand, the difference in performance is equally noticeable. I know of a couple that live quite happily on a Yankee, though two people seems tight for me. Also "living aboard" while cruising is very different than doing it while working in the "real world". As already mentioned, a mild climate makes things a lot easier.
