For ten years we had our cat at two different, very nice private-owned
marinas that allowed liveaboards. I got to know many of them and those were really nice people. Some had plans of cruising adventure, others were basically floating apartment dwellers. And there were a minority that had boats that were not
seaworthy, had trash covered finger docks, air condition ducting strewn across the
deck, the dog crap, etc. Albeit there were rules against this, in one of the
marinas the owner instead decided to end all
liveaboard leases. Basically not worth the headache of enforcing rules, extra bathrooms, trash pickup and parking, etc. Both were private marinas - so you cant blame the prohibition on
government.
