I've had 5 keel boats and changed the name on all of them, no evil ensued at least not yet. The problem is you never know whether that toothache or the premature balding was the result of name changing, or just normal bad luck.
Yes, I believe changing the name involves a lot of alcohol - pouring it down your throat, pouring it on the boat, pouring it over the side. Chants, incantations, offerings to Neptune....you've gotta do it right or there will be trouble!
one of the boats i sail was named maartje,after we paint it we didn't write the name on it so now everyone is calling it no name and the boat is doing even better it doesn't be the name that gives you luck it's the way you handle your boat
**** happens,maybe it's so i don't know but for the record just don't chance the name. its easy if u blieve in those things just don't do it. do believe but it's not the same with all name changes i don't know it can be the new name is ugly or so just thing good about it before changing
