Recommend me my next liveaboard boat (upgrade from Hurley 31 ketch)

Hey folks, I’ve been living aboard a Hurley 31 ketch for the past two years with my partner and our two cats. We’ve done about 5000nm so far — south coast of the UK, across Biscay, and into the Med — and she’s been an absolute tank. For just the two of us (four if the cats get a vote), 31ft has been pretty ideal. But once we add guests, things get cramped fast. We’ve managed a couple of trips with two extra people, but it’s definitely pushing it. So… we’re starting to think about upgrading. Right now the Nauticat 33 is high on my list, but I’d love to hear what else might fit the bill. What I’m looking for: • 60s / 70s era (keeping it affordable and solidly built) • Centre cockpit • Proper wheelhouse (so we can actually close the cats inside — current setup is a bit makeshift) • Comfortable space for 2 + up to 3 guests • Still manageable for a crew of 2 (roughly ≤40ft, but open to persuasion) I realise this probably puts me squarely in motorsailer territory, which I’m totally fine with. I actually prefer heavier, full-keel boats — speed isn’t a priority, and I value comfort and seaworthiness way more. Our current boat has handled some pretty unpleasant weather better than many faster boats heading back to port. Would love to hear your suggestions — specific makes/models, or even boats you’ve owned or sailed that fit a similar brief.
