Charles I was riding the 70 pound redwood Dragon board in small onshore surf, and lost the board. I swam after it and possibly because i'd been in training for the NZ Nationals arrived at the destination faster than expected. In other words I swam at full speed into the pintail. A small piece of resin had been chipped off leaving a sharp edge about 1/8" across, the board was rocking up and down in the swell as I hit it so scribed a nice big slice. The impact was pretty hard too but it didn't hurt. I drove myself to the doctor and luckily a top plastic surgeon was visiting the beach clinic so I got the best possible result. Thirty six stitches were used, that makes 46 to the head in total so far.
I won a watch in NZ Surfing mag's 'Gash of the month'.
