175 years ago this summer, Samuel Cunard was in Britain to set up his famous shipping company.
250 ships and the best known line in the world was to follow.
Today, just one liner remains carrying passengers between Southampton and New York.
The company also operates Queen Victoria and Queen Elizabeth.
For the last of his special reports, our Transport Correspondent Mike Pearse has been given exclusive access behind the scenes of Queen Mary 2 on her 200th crossing between New York and Southampton.
We talk to Executive Chef Nicholas Oldroyd, Environment Officer Emma Gale, Social Hostess Imogen Smart, Stephen Payne who designed the ship and Commodore Christopher Rynd.
