They aren't the only ones to have had issues, with former Olympic champion and America's Cup skipper Nathan Outteridge and his sister Haylee involved in a big collision on day one that forced an early finish to their racing but they recovered to post two top-three results on day two.
"It has been pretty eventful," Wilkinson said. "Everyone is still pretty loose in our fleet and when it gets over 20 knots everyone starts to get a bit wild so we kept it pretty simple and came away pretty happy.
"It was perfect Nacra conditions with flat water and big breeze and we absolutely loved it. We had big speed downwind and some of the leaders were tipping over in a few races so we got a bit lucky there keeping it upright, keeping it simple and coming through. In the last race we nailed it [to take the win].
Mackay and Wilkinson, like most of the rest of the Kiwi contingent, are using Kiel Week as a final shakedown before the upcoming sailing world championships in Aarhus.
Andy Maloney continues to impress after his switch from the Laser to the Finn (with and America's Cup campaign in between) and finished third in today's only race in the heavyweight dinghy to move up to third overall, three points off the lead. Josh Junior is ninth, but only five points behind Maloney after finishing fifth today.
The pair came into this regatta after finishing second (Junior) and third (Maloney) at the World Cup Series final in Marseille a fortnight ago.
Strong breezes are again forecast in Kiel for day three when finals racing gets underway and there won't be too many New Zealand sailors unhappy about that.
