HMY Britannia
From Tardis Wiki, the free Doctor Who reference
HMY Britannia was a yacht. According to The Herald, in November 1959 in an alternate timeline, King George VI, his wife the Queen, and princesses Elizabeth and Margaret returned from their "triumphant empire tour" on the HMY Britannia, arriving at Southampton. Rita Hawks was puzzled by this, as George VI had died eight years prior and Elizabeth was now Queen in her own timeline. (PROSE: Loving the Alien [+]Loading...["Loving the Alien (novel)"])
