Australian Harry Price cemented his status as the world's top-ranked match racer by winning the Governor's Cup, rallying to beat Leonard Takahashi of New Zealand 3-2.
Price, 22, showed his prowess in boat handling and tactics to win the world's oldest youth match racing championship for the second time in four years.
Sailing in strong wind and big swell, Price and Takahashi traded victories in the first two races.
The mast on Price's Gov Cup 22 broke in the third race, which was black flagged in Takahashi's favour.
After both skippers moved to new boats, Price won the next two races to claim the trophy.
