Woodman or anyone else that make a comment/suggestion,

Your day four itinerary caught my eye; "Day 4 Go do some snorkeling, perhaps go in at Flash of Beauty and drift snorkel to Big Bamboo in Loblolly." We will be in BVI in January and hope to make it to Anegada for a day trip from Tortolla, if I can talk my wife into the extended ferry ride.
Can you provide some details on the "drift snorkel"? Best place to access, how long you can drift, to where...
Thanks in advance!!
