New Zealand sailors Peter Burling and Blair Tuke remain well out in front heading into the last day of the 49er World Championships in Clearwater, Florida.
Burling and Tuke will take a healthy 28 point lead after sailing three gold fleet races in choppy, rough and challenging conditions.
It wasn't all plain sailing for the duo who recorded a 20th in their second race after an average start, but a 4th in the opener and a 2nd to close the day means they maintain their points margin on the pack.
Alex Maloney and Molly Meech relinquished their overall lead in the 49erFX slipping to 5th overall after placing 17th, 9th and 11th in today's gold fleet racing.
Meech said when they first got out on the water the conditions were good but the waves picked up and things got trickier.
After interruptions early in the regatta organisers added three gold fleet races to the schedule on the final day before the top 10 medal race, and the New Zealand women will be looking to put those to good use.
"One more day of gold fleet racing tomorrow and then a medal race, so there is a lot of points up for grabs and anything can happen," said Meech.
The other kiwi crew of Erica Dawson and Ellie Copeland go into the final day of the regatta holding 18th overall.
In the Nacra 17 World Championship, the NZL Sailing Team pair of Gemma Jones and Jason Saunders improved their overall position after racing on the penultimate day but not enough to make the top ten medal race cut off.
With moments of brilliance through the 15 race series the pair collected three top five race finishes but have been unable to maintain their consistency and finish today in 14th overall.
Aon Fast Track Squad sailors Olivia Mackay and Micah Wilkinson end the day in 17th place overall in the 43-boat fleet.
The Nacra 17 will debut at the Olympic Games this August in Rio.
