You do know about getting all old documents with the old name off the boat and ALL pic's with the old name off the boat as well, remove all log books
with the old name and anything else bearing the old name. It took about a week for us to get our yacht ready for the denaming and then we had to do the denaming cerimony twice because we kept finding receites with the old name. With all evidence of the old name off the boat your ready for lots of libation given to the 4 winds and yourself and of course real Virgin Pee for the base of the mast
to wipe away all past sins of the old name is in order. Doing the christing of the virgin boat with a new name is easier except to get live musiciations singing Sea Chanty's ( we had 2 singers) and the best bubbly you can afford ( or the flavor you like, even perscription herbs will do really good).
'Best of Luck' ( hay that would be a great name ) remember a good name is easy for someone on the other end of the VHF radio
to understand and spell.
