This rubbish about never changing the name of a ship is a load of mumbo jumbo. (IMHO)
Whether one should observe certain ceremonial procedure at the time of the renaming is the real issue.
Personally I think that's a load of bollocks as well but it is a load of fun and a bloody good excuse to get pissed as a parrot.
Anyway, bugger the Gods. Didn't do much bloody good for the passengers and crew of the Titanic did they ?
