The subject of dinghies is always good for a long conversation, but we would like to say just a few things. First, you must have one. You will definitely need it for getting ashore if anchored out. Most of the harbors on the ICW don't have launch service, and you may be forced to anchor out even if you plan on docking each night. Second, keep the dinghy handy.
Many cruisers simply tow the tender the entire way, while others prefer stowage on deck.
Third, inflatables with suitable motors make wonderful tenders, but they do not like oyster shells. Pilings and beaches are covered with these razor sharp shells throughout the Carolinas, Georgia, and Florida. One swipe down the side of the toughest fabric dinghy and that's the end. We've seen a brand-new boat destroyed by one ramming of the dock. You should also be careful when wading ashore or touching a piling with your unprotected hands.
