Interesting, the UK sovereign apparently was behind a last-minute renaming of naval vessel from "Agincourt" to "Achilles." The interesting thing is that it's thought to be bad luck, interrupting the unswerving course of setting sail somehow. Reversals and the action.
If the stories are to be believed, his predecessor renamed the vessel named after her at the christening, as there had never been a previous Queen Elizabeth in the nation where the boat was built.
