My experience with C&I in the BVI was that they will only grant a 24 hour grace period after clearing out. So, if you want to clear in and out at the same time, you have to leave withing 24 hours. I've asked and been told that several times, mostly at Spanish Town.
Rubikoop is correct in saying that, according to the law, you should clear in at Cruz Bay before mooring
anywhere in the USVI. That being said, I don't know if they enforce it, nor what their actual response would be if you stopped at Great Lamshur or somewhere to snorkel on the way to Cruz. You could play dumb. I confess to slipping over to Waterlemon Cay from the BVI for some snorkeling and overnight without clearing out/in, and I'm still here to talk about it
. I don't know if they patrol and check your "papers" in the USVI. I've read that they are doing so now in the BVI. They're pretty strict there, so don't fool around.
I did have this experience with CBP in Cruz Bay...We made an overnight passage
from Marigot, St. Martin, to St. John. We picked up a mooring
in Caneel Bay at 11 am. I took a shower
, shaved, and had a quick sandwich before dinghying around to the CPB office, arriving at about 12:30. The officer asked me when I had arrived, and I told him. He told me very emphatically that I should have come to CPB immediately
upon arrival. I countered that to come into his office unwashed and unshaven would be disrespectful to him and his colleagues. He laughed and processed me in.
in the boat must report to the U.S. CPB to "be inspected", as they put it. On every other island, they want everyone but the skipper
to stay on the boat while the skipper
comes ashore to do the paperwork.
