Rob Bell explores two iconic ships that have played significant roles in Britain's maritime and cultural history. From abdications and royal deaths to dramatic wartime heroics and daring rescue missions, these crafts reveal stories that give a unique insight into what is like to be a royal at sea, from the familiar to the surprising. The first episode covers Her Majesty's Yacht Britannia, which was in service from 1954 until 1997 and in her service sailed over a million nautical miles around the globe. The second episode covers RMS Queen Mary, which sailed mostly on the Atlantic from 1936 to 1967 and was also used as a troopship during the Second World War.
