The quarantine is not really 4 days. It is 5 days, at best. People coming in are not released from quarantine until their day 4 results are reported to them and they can have their tracking device removed. This is not on day 4. It is on day 5 (at best).

As is, this means that a 7-day charter is really not practical. The boat must report back to Nanny Cay on day 4 for testing, and must again return for the tracking device to be removed. So, a charter boat is essentially tethered to Tortola for 5 days.

With luck, day 6 is free, and return the boat on day 7. If test results time goes to 48 hours, the entire charter is spent in quarantine.
