@tsarstepan,
I had a teacher/later colleague who lived on a houseboat... where, sausalito, I think. Those houseboats got to be sort of famous, back in the day.
Not for me, but I can imagine owning one and enjoying it.
I've spent some of my last decades deriding rvs, which have similar attributes to houseboats in a way.. and found out, since I accepted a few days' ride in one, that I don't hate them as much as I thought I did. (Or maybe I do, much to resolve.)
I do like the whole idea of living lightly on land, and I like mobility as a concept.
