Technically these are mobile liveaboards, both the blue-hulled QV–somewhat sci-fi herself– and the tug Maryland.
These, which I posted about here last year, are mostly immobile.
Craigslist has one for sale here.
The blue Sandy G is a domicile that rocks (on windy days:) , not far from the Big Oyster (a must-read, by the way). I’d love to know something about the history of Sandy G. Read this link about the BQE imminently becoming a waterfront location like the canals of my favorite city, Amsterdam. Then again, if I moved back onto the water, I’d want a location like Bryan and Judy’s in Majuro.
Then there’s this option: take a fiberglass houseboat, attach a wraparound flotation deck not unlike Huck Finn’s raft, then add an expansion supported on the deck. Move in, and wait for strong wind. Eeek!
Much better versions from around the world here.
