Dear Noel & Carole,
Captain Warwick is the offical Master of the QM2. He was previously also the Master of the QE2. We had him on several trips and received our 100 day pins from him.
Captain Wright is one of the Senior Captains of Cunard Line. We also had him once on one of our cruises.
I believe that the Master of the Flagship is always made the Master of the New Flagship (ex. QE2 to the QM2).
