you either have to overcome your superstition, or leave the name as it is.
This superstition goes back a long way, to the days when the ships name was carved into the keel board, thus anyone( pirates ) for example would have to carve away some of the keel board to remove the name, thus weakening the structure of the whole ship, causing the keel to break in extreme cases,
This doesn't apply nowadays as ships and boats are constructed differently,
But the superstition still remains.
