Capt Force got it right.
in the keys most blue collar workers can't afford to live there, so many buy a cheap boat and live aboard. some are responsible, but many are not.
Efforts to remove them have not been successful so they are trying something else.
pretty much a few bad apples is spoiling it for everyone else.
I can understand why property owners and cities are upset. abandoned vessels are expensive to remove.
There has also been talks of requiring anchor permits in biscayne park...
-sorry, tourism from boaters is not a big revenue source...
