To each their own, but that arrangement sounds like a nightmare to me.
The first thing I would toss would be the yappie "small dog". Those sort of rodents would never have evolved but for the intervention of man with Natural Selection. At the first sign of a dog "mess" on board, over he'd go. There's no way the Captain is going clean-up after little Poopsy on my boat.
The second thing to go would be the wife. "No shower and no refrigeration" pretty much eliminates both reasons for keeping a wife around in the first place: cooking during the day and companionship at night. Next port, she's gone, too.
Having paired things down to just me and the 27-footer, the situation would then seem livable to me.
What a ridiculous way to introduce yourself.
