Name it "What Boat"
You'll have the chance to set off a "who's on first" routine everytime it comes up.
I hear it now:
"Have you named your boat?"
"What Boat"
"The new one you bought"
"That's it's name"
"What is it's name?"
"Yes"
"You named a boat Yes?"
"Of course not, that's no name for a boat"
"Then tell me your boats name!"
"What Boat"
"aaargh!!"
