NSWIS sailors Lisa Darmanin and Jason Waterhouse have tumbled down the leaderboard following a tough day on the water in the Mixed Nacra 17 class.
The Sydney cousins went into the final day of the series holding a slim lead but now head into the double-points medal race in fourth, nine points adrift of the top ranked crew from Argentina.
The Australians started the day in the best possible way, winning race 10 to further consolidate their standing.
But they couldn’t reproduce that result in races 11 and 12. They finished 12th and 17th as their main rivals for the medals dominated.
The Argentinian duo finished second (race 11) and first (race 12) in those events to surge ahead.
Darmanin and Waterhouse remain well in contention though with the medal race to carry double-points.
They sit on 74 points, just behind Italy (70) and Austria (72).
Any finish higher than those crews should see them win a medal.
Defending Olympic champions Nathan Outteridge and Iain Jensen are back in action tonight (AEST) in the 49er class.
It was a rest day and they Australians will be looking to return with the sort of form that saw them take gold four years ago in London.
They are currently in sixth at the halfway stage of the competition.
And NSWIS sailor Tom Burton returns to the water to sail for gold in the Laser class.
He is currently second overall, 10 points adrift of first, 10 points clear of third and 20 points ahead of fourth.
Burton will win a medal and could turn that into gold with a high result and a slip from Croatia’s Tonci Stipanovic who currently leads the competition.
