I will add the Cherubini 44, a ketch, cutter or sloop (depending on what the purchaser choosed) - a bit old by now (1980+), but really impressive under sail. Was semi-custom, can be found around 175k-250k with a little bit of negotiation. The displacement ratio is modern (under 200), you can find ketches of this model, this rig will allow numerous sail configuration. The interior space is decent. A bit of a wet ride if pushed too hard with the wind, but otherwise very impressive, especially when one consider the speed performance of that full (did I say full???) keel in lead.
Oh, did I mention the waterline? It has a LOA of 13.4 m for a LWL of 12.2 m. Really not what was mass produced at that time, and this should indicate sufficient space (ok, not built with thin and modern material, but still a 44'') and confort (it's not a hobby horse boat).
Plus these boats were still built in the 2000's (25 years of production run!)... So the design was really brilliant.
Look at Magic, the one at 259k, on Yachtworld, really beautiful inside, that sleeps six. The teak on board looks brand new and unworn (you could of course change that if you liked something else), the power is really good (a Mercedes 76hp, the maximum ever fitted to this boat), and I do believe it may even be the version 2 (I'm not sure though), that featured a couple of updates compared to the first version.
If you can find a Kaufman 47, it's the same boat that John Kretschmer owns. I see none for sale as of now. A really good value. He may give you some info about this boat, better than what I can say. I've not come across many of this brand.
Hylas 49, recent, aluminium. A review is available on the web. I know Hylas has a reputation for being a wet boat builder (because their yachts lie low on the water), but whether this is true for this particular model, I don't know.
Nautitech 47, catamaran. A good find, a good performer, average to a little under average space for the size, still a little faster than most of its size. It's recent, also. A review can be found on the web.
Alden 46, Bob Perry wrote a complete review of this one a couple of years ago. Looks a bit older, doesn't have 4 cabins but 3, and seems less confortable. Lots of teak to maintain. Is strong.
Bahia 46, by Fountaine Pajot. There more information to be found on the web. The reviewer clearly states he would consider it for bluewater cruising at the end.
Knysna 440. You can find a review on the web too.
I am still looking for other suggestions, but I think these would be suitable for your needs and requirements.
