The Japanese duo opened with another second placed finish, which helped them secure a five-point lead at the end of the second day of racing.

Austria’s Lara Vadlau and Lukas Maehr recovered from a difficult first day, where they received a black flag ruling, to win race four and move up to second overall.

Sweden’s Anton Dahlberg and Lovisa Karlsson sit just a point behind the Austrian crew after they sailed impressively to win race three of the 470 class.

The Mixed Multihull event also got underway today and it was Italy’s Tita and Banti who took control early. The reigning Olympic champions began with a point to prove, winning the first two races in windy conditions.

Argentina’s Mateo Majdalani and Eugenia Bosco finished the day only two points off the Italian leaders, after a strong second placed finished in race one and two.

Finland’s Sinem Kurtbay and Akseli Keskinen edged into the top three after securing third and fourth in their first session on the water.

How it works:

Medals for the Mixed Dinghy (470) will be decided by the cumulative results of the 19-strong fleet over 10 races. The boat with the lowest total will rank first. Athletes will be able to discard their worst finishing position after they’ve completed three races.

At the end of the Opening Series, the top ten boats in the fleet will qualify for the Medal Race, which is worth double points. The score in the Medal Race cannot be discarded. The crew with the smallest overall points total will win gold.
