HOUSEBOAT !
I've had Several cruisers, 30 to 42ft, and Several houseboats, no question in my opinion, houseboats are the cats meow for someone who ain't in a hurry to buy gas, Much more room,
half the gas consumption, based on a 10 knot cruise, and you can add everything you want/need, and never notice a loss of space.
My last houseboat was a 50ft KingsCraft, maybe 45ft ? all aluminum, semi-planning hull ? that's what it was called ? anyway, 80 yards carpet outside, including the flybridge, central heat/air, central vacumn. two 3i8 chry's, 20" screws, don't remember the pitch, but on plane it would turn 5500 rpm, scared me, bunch of gas, but cruise 2500rpm @ 10/12 knots on 10 gallon an hour and sounded Great.
two bedroom, living area forward, full bath, central heat/air, washer/drier, 4500kw Onan, spoiled me and the Fox, we lived on it two years, I worked for the marina.
I sold it to buy the house we live in now, paid for it, always regreted selling it, but it did set me up in the classic boat world.
WEe also lived on a 48ft Cargile with our son and a dog ... always Loved it.
I've had a 28ft scarab, 36ft Chris, 38ft sport fisher, and some smaller, but the house boats were the greatest. just my, and my family's opinion.
