Florida is hostile, not only to live-aboards but to marina owners/operators. Probably down to greed. Those waterfront locations don't pay nearly as much in taxes as condo and housing developments with canals.
I almost forgot: Stay away from the Manatee County ICW. There are those there who lurk looking for opportunities to 'legally' loot passing boaters.
