I lived aboard my 32 footer for eleven months between houses when I moved to Miami.
I got tired of not really having any space that was mine except for the boat.
But, my harbormaster and his wife, had been living aboard for thirty years, and were happy as clams (in a 51 foot houseboat). When you got inside their place, you barely knew it was a boat. My son asked them why their was a steering wheel in their house, once, when we visited them, later.
But, I also lived on my 42 foot sailboat four about 8 months, while cruising, mostly anchoring out, and I never got that claustrophobic feeling. So, there are pros and cons to being tied up to the dock versus at anchor, when you live aboard.
