Not sure where exactly you are talking about? I can think of one or two, but that's it. One is No Name Harbor (just south of Miami). There is also an area in North Lake Worth
that is supposed to have anchoring fees
. Just anchor outside that imaginary line where everyone else is.
Many other areas with moorings offer dinghy
dockage, showers, etc., at no additional fee (other than the mooring
charge). If anchoring near these mooring
fields, you can use the docks and facilities, but will have to pay for the luxury (Boot Key is one example). Maybe this is where some of your confusion comes in?
