My a friend in Galvaston, Tx. a certified Captian, took the name off a boat he wanted to change, he recovered most of the residue from the name on the boat in a plastic jug he cut in half with a box knife, he bought a half gallon of Crown Royal, that evening we met at the boat, he mixed us up a couple stiff one's, just ice & Crown, he re-hearsed a toast a couple times, refreshed the drinks, made the toast to the boat, dumped the residue in the harbor beside the boat, then poured the rest of the Crown into the water over the residue, I don't think I need to tell you what I thought about wasting the rest that Crown. I had just bought the boat in the next slip, 38ft sportfisher, the "Sea Cob" one of my favorite boats ever, 24ft outriggers, two fightin chairs, 7 navigational radio's, auto pilot, radar, 10 man life raft that would deploy automatically @ 90 degree list and elt, counter rotating 427 Chevy's, two 400 gallon gas tanks, chilled air cond, all self contained cabin & galley .. Loved It !
One week later, a hurricane came in, sunk his boat, pulled the line's from mine, put it against the concrete sea wall, sawed about 4" off the gunwale, that looked kinda Odd, got a call from the harbor master, he was wanting to blow a hole in it, sink it, to keep it from causing more damage in the harbor, cost me $380 for them to lift it out of the water with the travel lift to dry dock, cost me $7000 in all. The name Calvin had chosen for his boat was the "Gayle Force" his girlfriend's name was Gayle, she didn't stay around long either.
I think re-naming a boat deserves a ceremony, I did that when I changed the name on my scimitar from "Once Again" to "Reds Gold" when I backed it in the water, I poured a can of Bud Lite over the bow, wiped it off quick with a wet towel, said Out with the old and In with the new, fired that sucker up and went for a ride, worked for me.
Pic of the "Sea Cob" the name actually means a bird, not a fish
