Young clinched the boy’s laser radial title despite finishing seventh and 11th in the two races that took place as he finished with an insurmountable total of 21 points, ending the hopes of American Nicholas Baird and Oskari Muhonen of Finland.

The two sailors look likely to battle it out for silver tomorrow, with Russia's Kirill Evfimyevskiy and New Zealand's George Gautrey both still in contention for a medal.

“After finishing fifth last year I really wanted to improve on that and get to the top, so I'm stoked, couldn't be happier,” Young said.

“The Youth Worlds is a totally different regatta to anything else that you can do and having one under the belt, the experience has helped me heaps.”

Logue and Brakman, meanwhile, secured gold in the boy’s 420 class in style as they sealed victory in the day’s final race, which came after a fourth-place finish in race one.

Their score of 16 points now cannot be beaten, leaving Australia's Alec Brodie and Xavier Winston Smith, Leonardo Lombardi and Rodrigo Luz of Brazil and Irish pair Douglas Elmes and Colin O'Sullivan to contest the other two medals.

The Australians have a four-point advantage ahead of the other two teams on 31 going into the conclusion of the regatta tomorrow.

Elsewhere, two victories for Poland's Julia Szmit and Hanna Dzik lifted the duo into gold medal position in the girl’s 420 ahead of Nia Jerwood and Lisa Smith of Australia and both teams are now guaranteed a top-two finish.

Hungary's Maria Erdi remains on course for gold in the girl’s laser radial on 19 points, with Germany's Hannah Anderssohn her closest challenger on 26 points.

France's Louis Flament and Charles Dorange, who have been the dominant force in the SL16 event, moved a step closer to taking the title as they recovered from a disappointing fifth-place result by recording three victories.

Titouan Le Bosq, also of France, has guaranteed himself a medal in the RS:X class after he came home first and second from the day’s opening two races, maintaining his position at the top of the leaderboard despite coming 15th in race three.

Le Bosq has 40 points on top with Argentina's Francisco Saubidet Birkner 12 adrift in second.

Defending champion Stefania Elfutina of Russia leads the way in the girl’s RS:X on 21 points in front of China's Xian Ting Huang and Emma Wilson of Britain.

The destination of the gold medal in the girl’s 29er competition will go down to the wire as three points separate the top three.

Finland's Sirre Kronlof and Veera Hokka currently lead on 42 points, with Spain's Carla and Marta Munte Carrasco and Denmark's Laerke Graversen and Iben Nielsby Christense hot on their heels.

New Zealand's Jackson Keon and Nick Egnot Johnson and Slovenia's Peter Lin Janezic and Anze Podlogar will go head to head for gold in the boy’s 29er tomorrow as the two teams are comfortably ahead of the rest of the field.
