To clear in you can tie up to the North Dock, take a mooring, or tie up in a slip at Harbour Marina. You may only stay at North dock while you are clearing in. The customs building is at the head of the dock.
Clear first at Customs and then go to the Immigration (pink building) in town. If Customs and Immigration are closed, go to the Police Station (adjacent to Immigration) in town to announce your arrival. Open 24/7, however, they are often closed Saturday and Sunday afternoons as well as weekdays from 12:00 to 14:00 for lunch. They are very friendly and efficient.
No charges unless you need a ZARPE on check out. A ZARPE from the previous port is required.
Flare guns and spear guns are considered weapons and they will hold them while you stay in the country.
