We used a water taxi St. Thomas to/from BVI this past July, and scheduled again for late October. Our charter is with Voyage Charters located in Soper's Hole. We got lucky in July and they took us straight to West End to clear C&I and waived the arrival Covid test (although we had already paid for it through the portal). We were all vaccinated. The water taxi then took us across the way to our boat at Voyage. That said, the folks at the water taxi warns us this next trip we will likely be required to go to Road Town to clear C&I and take a Covid test before they can take us to Voyage Charters. It might be that your group will also be required to first enter at Road Town before your water taxi can take you to Nanny Cay. It seems all so fluid, just go with the flow.
