I am not a huge fan of BB, but...
I think the rush of BVI boaters to the USVI during COIVD showed that there was a need for expanded mooring coverage in the USVI. If I remember the pressure on the National Park moorings was intense. Moorings outside of the national parks were largely taken by locals.

What to do....what to do ???

Some forward-thinking company might see this as a business opportunity. Looks like Boaty Ball did just that. It will be interesting to see how well the BB BVI business plan works in the USVI.

I will continue to use my anchor whenever/wherever I can, but occasionally, a mooring ball ( FCFS or reserved ) comes in handy.
I personally look forward to trying out a couple of new ( non NPS) anchorages in the USVI that I would probably have passed on before mooring balls were an option.

Cheers.
