Who''''s living on what??
My girlfriend and I will attempt to live and cruise on a 46'' Tartan for several years. It has lots of systems: two AC units, Heat, Refridgeration, Deep Freeze, 5lb a day Ice maker, 250 gal per day water maker, electric winch, and great sailing electronics. Problem is, the boat is 10 years old and what is supposed to be a relaxing sabbatical will more likely turn into a race to keep one step ahead of system failures.
I just got back from living on it for three weeks and a 500 mile shakedown and it looks like I will be spending another year preparing while I attend vocational school learning about diesel engines and refrigeration. Smaller is better unless you''re going to be tied to a dock.
