Whatever name you think you want to use, the acid test is do you feel ok, or a bit foolish, yelling it out in a bit of a panic over VHF to the coastguard, or worse still as a MayDay. I've seen so many cute boat names, which would make me cringe to have to say out loud in one of those situations, or even hear it over the VHF.
A friend called one boat he had "Comfortably Numb", after a favourite song, by a favourite band. I don't think he'd thought of that test..?
