CDC LINK

Possibly up to 100 days or more?

A small part of the article:

"This Order shall continue in operation until the earliest of three situations. First, the expiration of the Secretary of Health and Human Services’ declaration that COVID-19 constitutes a public health emergency. Second, the CDC Director rescinds or modifies the order based on specific public health or other considerations. Or third, 100 days from the date of publication in the Federal Register."

I believe that only applies to US based ships and not the many European registered ships.

I’ve read they (The cruise lines) read that Thus far more like 30 days more at the moment, hoping for the best.

They may not be US registered, but the “sails” taking place from MIA, FLL, etc are governed by CDC.

US based and European registered is two very different things, and not really any comparison. I am not really sure what you are trying to say. Look how many ships port in the US and virtually NONE of them are US flagged or "registered" if that is what you are referring to. At one time there was a US flagged cruise line that did the Hawaiian Islands but that is the only one I recall, other than some of the really small boats that do like river cruises.

While most cruise ships are NOT US flagged, most all the companies that own them are publically traded companies on the NYSE. Trust me, the CDC will control cruise ships that port in the US.

To clarify I was indicating that the CDC ruling has no authority over foreign ships going to ports not part of the USA or US Territories.

The only major cruise line ship that is flagged in the US is Norwegian Cruise Line's Pride of America. It only sails in Hawaii. You are right though, this order applies to all ships that would leave US ports, no matter what countries flag is on the ship.

My thinking is that when the major cruise lines get the green light to resume business, future passengers should be required to provide proof of that year's influenza vaccine and also be required to be tested for COVID-19 even after things settle down. The question is will the general public ever regain their confidence in cruise ships again. St. Maarten ports-of-call, IMO, are essential down the road because they work to introduce new visitors to the island. Let's hope they get this right when the time arrives.

Did you ever travel anywhere where a Yellow Fever vax was required? If you did, you remember the Yellow Card. As to ever cruising again? Not even in my great great grandchildren's lifetime.

No, I never have. I am with you on the cruising and have felt like that for 10+ years, way before Covid-19.
