Even that ship operates under
special conditions/restrictions as it is not fully built in the U.S. (hull laid down in the U.S. but completed in Germany). It's pretty much restricted to operating around the Hawaii islands and IIRC can operate to the mainland U.S. when repositioning for dry dock work.
However, the exemption limits the markets these ships may serve. NCL is required to keep the ships in "regular service" in Hawaii and is restricted from using the exempted vessels for transporting passengers to ports in the Caribbean, the Gulf of Mexico, or Alaska.
