"Finishing this event, we have a few regrets, definitely, but we also left everything out on the water and we are left really motivated for our next regatta."
The pair now head to Kiel Week in Germany, a regatta they have targeted as one to try different things as they look to turn silver into gold at the 2020 Tokyo Olympics.
Fellow Kiwis Josh Porebski and Trent Rippey finished fourth in the 49er medal race to finish eighth overall in the 16-boat fleet. It was a solid result for the pair who are New Zealand's best 49er crew on current form with uncertainty over the Olympic futures of Peter Burling and Blair Tuke, who are heavily involved in Emirates Team New Zealand's America's Cup campaign.
Porebski and Rippey had six top-five results but also made a couple of costly mistakes, not least of all being black flagged after being caught over the start line in race three.
New Zealand's Sam Bullock finished ninth overall in the IKA Formula Kite.
