This morning I was able to get information on COVID-related entry requirements into the SVI. I called the number listed on https://travelsafe.pr.gov and was told that to enter the SVI by sea on a chartered sailboat from St. Thomas, every person on board would need a negative result from a PCR test taken within three days of arrival in the SVI. And every person on board would need to complete a travel declaration on https://travelsafe.pr.gov.

Then, per https://usvitravelportal.com and https://usviupdate.com, to get back into the USVI from the SVI, every person on board would need a negative result from a PCR or rapid test taken within five days of commencement of travel to the USVI. And every person on board would need to make a submission through https://usvitravelportal.com.

So, that's not very attractive from a logistical convenience point of view. The https://travelsafe.pr.gov person I spoke with did say that the SVI entry requirements could change between now and my December charter. But I don't hold out much hope that it will get easier.
