Not trying to ruffle feathers but the Voyage 60 is to big for the NPT Moorings other then the yellow balls with heavier ground tackle.

MOORINGS + ANCHORAGES
In order for sailors to enjoy the many beautiful sites both above and below the water, The BVI National Parks Trust has installed more than 200 mooring buoys (surface buoys attached to stainless steel pins set in bedrock) for daytime use only at many BVI dive sites. The system has been operating since 1991, and is aimed at protecting the fragile, underwater marine ecology from physical damage, particularly by boat anchors, and maintaining the pristine reefs for the future.
There is a 90-minute time limit on all moorings, and use is on a first-come, first-serve basis. Vessels over 55 feet in length or over 35 tons may use 18-inch diameter yellow buoys only.
