I visited the Tortuga's last year and am planning another trip at the end of April, we left marker "2" here in Hudson
and arrived 72hrs. later. We entered from the south boundary marker "P" and on to "R2" / "G3"..ect. also the channel running between Garden and Bush is now open but not well marked, the Fast Cats from Key West
are using it and say 8'-12' . I choose to stay on the Conservative side and followed the channel running between Bird and Garden Keys to the Anchorage by the fort and had no problems.
