Is there a ferry from Miami to Nassau?

No ferry service between in the sense of a ferry that carries both passengers and vehicles. Charter service and regularly scheduled liner services are available from the port of Miami. If you need a vehicle while in Nassau, there are rental companies to serve you. You may also want to seriously consider the extra insurance coverage offered. Check with your personal insurance carrier, they may not cover you, a vehicle or anything else while you are in the Bahamas. Short term insurance policies can be purchased prior to your departure or after your arrival. I hope this helps. Enjoy.  more
