You do not need to hang around at anchor
. The Authority Office is on the Eastern side so if you simply park up on the west side, no one will know you are waiting.......
The protocol when coming fromt he west is to radio
Authories as soon as you are close enough to reach them and advise of your ETA. They speak English
and will give you feedback on when you can enter. As others have said, you tie up and pay on the eastern side so when approaching that side don't bother to radio
Be aware it is narrow so one way traffic flow. So they tend to run 'convoys' and therefore letting them know you are arriving before you get there should minimise any delay.
A stunning experience. Enjoy.
