Part one of two. Rob Bell examines iconic ships that have played significant roles in Britain's maritime and cultural history, beginning with the Royal Yacht Britannia.

Part two of two. Rob Bell examines RMS Queen Mary, the most famous ocean liner ever built and the first merchant naval ship ever to have been launched by a reigning sovereign.

Rob discovers how the vessel would come to represent the golden age of ocean passage and epitomise 1930s style and elegance - even going on to capture the prestigious Blue Riband for the fastest Transatlantic passage.
