Speaking of the Queen MaryII,,,,one of the other crew told a story of coming accross her. When the radio operator found out the boat name, he responded by saying something like "roger that QEII". A very formal british voice corrected him over the radio saying, "this the vessel Queen Elizabeth II." I guess those brits don't appreciate informality.
On Lake Michigan I paged the Motor Vessel Badger, identifying myself as Sailing Vessel Compass Rose. The reply was a very quick correction, it was the Steam Ship Badger, not the Motor Vessel Badger. I think they used to be quite proud of the fact that they burned coal.
