Naming the boat

Just applied name to my sailboat. Now, instead of a silly "Nauti Buoy" it's a majestic and musical "Violina" (my mother's name actually). The red burgundy color rhymes well with jib sail protective band, jib sheet, main sail cover etc. The boat definitely has a red accent theme going. Even new cabin cushions my mother made and new cabin stereo speakers are red. Now, what would be a correct procedure when renaming the boat? It I try to break a champagne bottle off the side of the boat - I'm afraid the boat will break first :-) There must be something else... Well, at least we'll drink to that tonight!
