ok another dumb covid testing ?

We are in the BVI. We will take ferry back to STT on 3/21 and have flights home on the 22nd. My read of the "rules" indicate entry by ferry we need a test at within 5 days of travel. Once we clear the ferry customs are we good to go or is there additional checking of paperwork once we get to the airport next day? I'm assuming no since it is a domestic flight but you never know.
Thanks

After clearing ferry customs/health immigration and showing your USVI portal acceptance with your negative test within five days of that date,, your covid testing is done! Congrats.

No covid testing at airport at all for departing passengers.
