I agree with rubikoop and the previous posters - Walker Mangum's charts and approaches are the "bee's knees". These days, during season, there is a veritable highway of boats heading betwen the North Sound and Anegeda so you could always follow a boat that looks like the might know what they are doing into the channel with sufficient distance between you so that you can stop and use your GPS
track to get back in case things go wrong.
I always head
up to Anegada but with my new boat and deep keel
I'll stay on the safe side and anchor
on the outside close to the first buoy.
Whatever you do, don't follow the chartplotter
into the channel; all of the Navionics
charts for the BVI are very accurate with the single
exception of Anegada; following the chartplotter
will let you visit the "two sisters" closer than you might like.
