At this point I have to ask if the vessel already has had a name? If she has (all ships are she's btw) it is very unlucky to rename her. The correct process is:
1. Offer the vessel the new name
2. Strike the bow of the vessel with a bottle of champagne once only
If the bottle breaks the vessel has accepted the new name. If not you need to leave her old name in place or risk the wraith of Neptune.
Just thought I'd mention it..........
