Britain's Ben Ainslie has won his fifth Finn world championship after coming second behind team-mate Ed Wright in the final race in Melbourne.
Ainslie once again demonstrated his dominance in the Finn
Ainslie, 30, the Olympic Finn champion who will defend his title in Beijing this summer, said he was delighted with his hard-fought win in the Gold Cup.
"It went down to the wire in the last race and this was as close," he said.
"There's real strength and depth in the class now. I look forward to lots of hard work up until China."
Ainslie had been only a point ahead of New Zealand's Dan Slater going into the final race, and needed to finish second to win the regatta.
The Briton got away well at the start and soon opened up a healthy lead over Slater, but Ainslie revealed he almost pushed too hard at the end.
"I had a bit of a skid out halfway down the run to the finish which wasn't far off a capsize," he said.
Ainslie added that the win ranked as the hardest of his five title successes, along with his 2003 victory.
The Lymington sailor, who also won Olympic gold in the Laser class in 2000 and silver in 1996, finished just a wave behind Wright in the medal race, which is restricted to the top 10 sailors after eight races in the 82-boat fleet.
Wright, pipped by Ainslie for Britain's Olympic Finn spot in Beijing, finished the regatta in seventh.
