You probably wont find much written about anchoring
in Bermuda because, except for the commercial
channels and the private yacht clubs, you can anchor just about anywhere you feel safe to do so.
There are no controlled mooring fields of a type you would be familiar with, and its basically put the hook down and relax...
All of Castle Harbour, western end of Ferry
Reach, east, south and west sides of St Georges harbour, the entire shoreline of the Little and Great Sound are at your disposal, as are all the islands area at the approach to Hamilton Harbour.
We are pretty laid back about this in Bermuda.
Any particular concerns, let me know and I will get you an answer.
