This. Being an ornery git, I'd wear that name with pride - and plenty of space around meOr keep the name, as you will get plenty of space round you on pontoons, and nobody trying to raft up alongside!
Changing a boats name is risking the wrath of the sea gods in my totally irrational, old fashioned and paranoid opinion.
I am just glad that my boat, Chlamydia, has such a pretty name and does not need it changing.
