Is there shipping from Florida to the Bahamas, which is not a cruise?
I was watching the shipping options from Ft Lauderdale to the Bahamas and all the "cruise vacation" or "casino cruises. What about the "only means of transport" options? in the 1980s I would fly from Ft Lauderdale to the Bahamas on a single means of transport and ferries ran every day. Why end the "transport only" options? Does anyone know?
Normally there are private boats traveling to the Bahamas from Florida. The same goes for ships Bahamas post daily traveling to Miami and Fort Lauderdale to stop mail and packages in the mail system in the U.S.. You may consult any person in the various marinas in Fort Lauderdale, if you have contact information for private landowners who operate private cruises. You can also call port officials Port Everglades at (954) 523-3404 to find out if they know of a passenger ship traveling frequently and not cruise the Bahamas.
