I have a question, my gf and I were in Miami today and stopped by a Miami harbor. We saw the CBP show up with border patrol. It seems if you sail to lets say the Bahamas you have to tell them when your going and when your coming back, Is this really true.
If so what happens if you go, and you don't checking with them, how are they or is anyone to know you are going to sail out of the country. This sounds serious.
