This must be a rare occasion to have one of the Maersk B class the fastest merchant cargo ships in service alongside the fastest large passenger ship in the world.

The B class achieved 32.5 knots on trials and Queen Mary 2 slightly less, both being capable of 29 knots service speed.

The fastest large merchant ships built remain, the United States for Passenger ships and the Sealand SL-7 class now in the USN.
