We took antigen at YVD on Thur morn 12/9. One positive . When returned to Moorings, Dr. came and antigen tested everyone (just one positive), quarantined ship and everyone, contacted Health Dept. Next day they were to come for PCR testing, but the negatives from YVD already has USVI entry permit (green QR) from day before. Came next morning and let all negatives depart on Fri. The positive was PCR tested by health official Fri afternoon and moved to the Mooring overnight hotel and still remains there today Wed 12/15 & days after arriving) . Downside is our fellow boater is in total limbo with no definitive info from Health officials. They do not seem to be very clear on a declared protocol. The conflict (from afar) seems to be BVI requiring PCR negative vs USVI require for antigen negative. One of our (all-vax) group returned and tested positive to PCR 2 days after negative antigen test.
Moorings has been very helpful, but they are also frustrated.

Take aways. Although everyone entering BVI is tested (most vax) the virus is present. We when visiting all the popular bars and restaurants, it pays to observe the same precautions used in US. When taking re-entry antigen test, if positive, take it again.
