If you are superstitous and desiring to change the name of your vessel. You should call in the local Priest, Minister, Shaman, Iman, Druid and Wiccan to rechristian your vessel with the appropriate Wine, whiskey, bourbon sacrifices.
Oh! leave a little bit of that sacrifice for yourselves. After all you need to be sure that the liquid you are using in the christianing is of the appropriate vinage. Replace the coins under the mast. These are used to pay the ferryman for the trip across the river Styx if things do go wrong in the big way.
And also have your spouse's permission for this Rechristianing party. She/He may want to add to the Rechristianing Ceremony with additional ideas.
After all it is a family boat.
Also do the paperwork for your state registry or USCG documentation. Most important item here and the registry for you EPIRB, and the FCC license also.
