The Moorings and Sunsail have a planning chart with the red zones marked. Each company has slightly different rules. With GPS on every boat Anegada is less and less of a issue. White bay on the other hand is becoming more and more of a issue with charter companies. I would not be surprised to see overnights there banned by all companies at some point in the future.
Regardless of the legalities White Bay is only a safe overnight with a perfect weather forecast. That happens maybe 10% of the time.
