Hi Rick. The Boaty Balls are pretty much grouped together and it is obvious (by color) which they are upon entering an anchorage. The BVI Mariner site we maintain has mooring ball counts, but not a layout of the field. Anchorage and Marina pages are currently being updated to ensure accuracy ... see the Oil Nut Bay page here for the new layout which includes a Navionics chart and Windfinder wind & weather forecast. My son is in the aerospace industry (Go Hokies) and hooked me up with a company that does daily satellite imagery ... we were thinking of adding these images to the Anchorage pages as well. Hope this helps.

Thanks! - Mark
