Mike M - yes I meant Triumph not Liberty - mea culpa.
With Carnival and Costa ships coming out of the same shipyard (at least most have, right?) it might be reasonable to assume the working portion of the vessels are pretty similar.
The crew accident on the Thomson (sp?) ship over the weekend demonstrates the danger of a passenger transfer. Of course that didn't get much press here because it didn't involve Americans.
MSC is a good organization. I know they did/do a lot of work out of Port Canaveral. They operated some of the tracking ships we used for launch support ops.
