Wait til it's +25knts and go for a sail. Afterwards, share a few frothies with yer mates and rub it in how good your new boards is. Don't wash the salt off if it. Take it home, kick the missus out of bed and sleep with it in your comfy bed.
I believe you take it out, commit to a full on catapult and as a consequence split/crack the nose open.......tah dah new board suitable christened.
I have done this, and I know of at least 2 or 3 others that have also done the same.
Nothing brings you back to earth quite as quickly as seeing you new and expensive toy with a big crack through the nose that is completely of your own doing.
barrycrocker reckons you should just go out with it and try something that you haven't tried before on ya first run out like a forward etc. then the board is christened. don't wast beer on it. beer is for drinkin not pouring over boards
