This time, Dawson's mother had nothing to do with it.
Kay Dawson, a judge for the event, penalized her son two seconds for hitting a gate on Sunday.
Mike Dawson still qualified for the semifinals, but he missed a wave toward the end of his run and failed to go through two consecutive gates.
Each miss cost him 50 seconds, putting Dawson in last place. But Kay Dawson was stationed at an earlier gate, which Mike passed through without any issues.
"It's a sport with so many variables. It's real easy to make mistakes, especially when you're racing semifinals and you're pushing everything to get one of those elusive 10 spots which fill up pretty fast," Dawson said. "There's no holding back and trying to play it safe."
Known affectionately by his mates as "Mutant", the Waiariki Institute of Technology's Sports Academy student had to watch from the bank of the man-made course as Italy's Daniele Molmenti won in a time of 93.43s to take gold, with Czech Republic's Vavrinec Hradilek and Germany's Hannes Aigner taking silver and bronze respectively.
