Two things to watch. Make sure you have the proper paperwork for the boat. If it's a U.S. owned vessel that would be the Coast Guard documentation.
At Cruz bay don't show up right after a ferry if it has come from the BVI. Stay on the boat a bit longer and enjoy a cold one if a ferry just passed your boat and turned in.
One last thing. You are supposed to fly a yellow quarantine flag until you have cleared. Rarely done but the park rangers could hassle you.
