Probably not quite enough space for your proposed idea, but I have an Islander 40 motorsailer I'm looking to get rid of. Has a forward cabin, main saloon with convertible dinette, and a separate aft cabin (crew quarters?). I bought it a number of years ago as a rehab project which hasn't worked out for several reasons, mainly wife's health and mobility. Hence the move to a single level trawler.
Issues: Structurally sound but in pretty poor condition systems-wise and cosmetically; pretty much a complete rehab needed. And it's on the hard on the east coast and would need to be trucked to...wherever. On the positive side, I'd let it go for a song - even an out of tune one.
