On Anegada, I frequently see charter boats dock at the Anegada Reef Hotel dock. They are usually catamarans. I think depth would be an issue for a monohull. If you are chartering a cat, I would ask your captain to call and speak to Lawrence at Anegada Reef Hotel to ask docking permission. I'm sure he will help you out.

If not, it's possible to pull up to the ferry dock temporarily.
