Peter Burling has outclassed a number of leading America's Cup sailors to win another title.
The Olympic silver medallist and double world champion in the 49er class won the Moth-class world championships near Melbourne in emphatic fashion, winning nine of the 14 races and not finishing outside the top 10 once.
Burling said it was an incredible run.
"[It's] pretty cool to be honest,"he said. "I've definitely been saying that all week.
"I've always been a bit worried in the back of my mind that these boats are so fragile and so easy to break something."
