The
Bahamas is being pretty lenient with timing of post-arrival tests for cruisers. The
current requirement is a test on the fifth day. If you are in transit to an island with a testing location on the fifth day then you can just state that on your arrival and get the test on the 6th or 7th day as the case may be.
This is generally true for the test you need prior to arrival as well. If for example you sail from
Newport down to the Bahamas you will not arrive in the validity window of the test. However, they will allow extra days if you can reasonably show you were at sea. if you want to claim it took you five days to sail from
Florida to
Bimini this exemption is not going to
work. Not leaving
Florida for four days because you are waiting on better
weather and don't want to bother getting a new test is not the same as being at sea.
They will not accept your own test, even the proctored variety, for the post arrival test.
