If your really serious about finding some taxes to save on while living on
your boat, you might try challenging the State of Calif. (and county) on the
personal property tax they charge on all boats.

It seems you might have a good case since the boat is your residence and
shouldn't be consider personal property.

Even if they come after your boat for real estate tax, the taxes would be
much less than what they charge for personal property tax.

However, since it take a couple years for you to get your first tax bill,
you probably shouldn't consider messing with the assessor until you get a
bill..

Only half way serious!
