They will take that pdf from eMed - the real question is about the test at the terminal. The new rules say that if the test was conducted within 48 hours of the trip (2 days, really) that you won't need the test in Road Town. Those rules change came after I made the trip, so don't know exactly how the ferry people do that.
When you get off the ferry, the break the group into 2 lines. Those with tests taken within 2 days of travel and those with older (must be 5 or less) tests.
The first group goes directly to immigration and starts to clear. The 2nd group goes thru the testing process.
