Virgin Anchorages
I have also found the book "Virgin Anchorages" to be very helpful. The book contains beautiful pictures of many of the popular BVI and USVI anchorages taken from the air, as well as helpful advice for entering into the anchorages. I would use this book as a companion to either the Scott or Doyle? (I don't remember who wrote the other major BVI cruising guide, but I have used them both and they are both good) cruising guides for both planning your trip and navigating once you are down there. I know I have had Virgin Anchorages up in the cockpit with me entering anchorages several times - I highly recommend it.
