Why are crew members required to use noncommercial travel if they are on a “COVID-free” ship?
section_content: At this time, given the limited availability of testing onboard ships and
inconsistent reporting from cruise ships, CDC does not have confirmation or
evidence that any cruise ship is free of COVID-19. We are currently in a phase
of the pandemic where it is necessary to implement strict measures to control
the spread of COVID-19. Just as the American public has a role to play by
practicing social distancing, cruise lines have a role to play in limiting the
contact their crew members have with the public when disembarking. This is why
CDC has provided instructions for the safe disembarkation of crew in a manner
that will not endanger the public’s health. We are hopeful that more cruise
lines will take advantage of the opportunity to use the attestation process.
Crew members who remain at sea and want to disembark should contact their
cruise ship or cruise line about meeting CDC requirements for safe
disembarkation and transport.

Reviewer feedback on this answer:
This answer is incomplete. It does mention cruise members disembarking but doesn't really say what the procedures are. There should be a link to more information or something detailing the expectations of those people
This answer is too generic in regards to taking covid precautions and could use more information about disembarking.

What are the requirements of the attestation that cruise lines are required to sign before crew can disembark, or transfer to another ship?
section_content: By signing the attestation form, cruise ship operators agree to follow
specific conditions that are designed to allow crew to safely disembark while
protecting public health, including the following:

Arrange to transport crew members to their final destination (US or overseas) by industry-chartered private transport, industry-chartered private flights, or personal vehicles (no rental cars, taxis, or ride-share services) with measures in place to ensure neither those involved in transport nor other members of the public are exposed to the disembarking individuals.
Screen disembarking crew members for symptoms of COVID-19.
Ensure crew members with known exposures to COVID-19 are transported separately from those with no known exposure.
Provide face coverings, such as a cloth face covering, to disembarking crew members or confirm that they have their own face coverings.
Instruct disembarking crew members to stay home for 14 days and continue to practice social distancing after reaching their final destination.
Ensure disembarking crew members: 
will not stay overnight in a hotel before the flight or at any point until they reach their final destination
will not use public transportation (including taxis, rental cars or ride-share services) to get to the airport/charter flight
will not enter the public airport terminal
will not take commercial aircraft after an initial charter flight
will not have a transportation layover exceeding 8 hours
will not have interaction with the public during their travel home or to their new duty station (e.g., rental car companies, restaurants, other public areas)




Reviewer feedback on this answer:
The question doesn't fully make sense but this seems like a pretty relevant answer. It's talk about precautions that should be taken on the cruise ship which is what I think is being asked
This answer provides plenty of information detailing the special arrangments that need to be taken when disembarking.

What is CDC’s legal authority for preventing crew who are U.S. citizens from disembarking cruise ships?
section_content: CDC is using its legal authority under the No Sail Order and 42 CFR 71.31(b),
71.32(b) to stipulate specific conditions for the safe disembarkation of crew
in a manner that will not endanger the public’s health. Having cruise lines
sign a legal attestation is one method of ensuring that these conditions have
been or will be met. CDC is not detaining crew who are U.S. citizens or
preventing them from entering the United States. We are hopeful that more
cruise lines will take the necessary steps to ensure that their crew members
get home safely in a way that will not risk the health and safety of our
communities.

Reviewer feedback on this answer:
This is just talking about a no sail order but doesn't really get into any details. There's mention of signing a waiver but there's not enough information here.
While this answer does talk about cruise lines and getting passengers home safely, it is too brief.
