Spanish duo Jordi Xammar and Nicolás Rodríguez and British pair Hannah Mills and Eilidh McIntyre lead the respective men’s and women’s standings after a day of racing at the 470 World Championships on Enoshima Bay in Japan that saw the top-10 medal race line-ups decided and Tokyo 2020 nation qualification spots earned.

Greece, Russia, China and Turkey have secured the four men’s nation qualification berths for next year’s Olympic Games in Japan’s capital.

That came courtesy of the performances of third-ranked Greeks Panagiotis Mantis and Pavlos Kagialis, 11th-ranked Russians Pavel Sozykin and Denis Gribanov, 12th-ranked Chinese Xu Zangjun and Wang Chao, and 13th-ranked Turks Deniz Çınar and Ateş Çınar after a total of 11 races on the Sagami course at the venue being used for Tokyo 2020.

The six women’s nation qualification berths have gone to Poland, Australia, Brazil, The Netherlands, New Zealand and Germany.

This is thanks to the displays of seventh-ranked Poles Agnieszka Skrzypulec and Jolanta Ogar, ninth-ranked Aussies Nia Jerwood and Monique Devries, 10th-ranked Brazilians Fernanda Oliveira and Ana Barbachan, 12th-ranked Dutchwomen Afrodite Zegers and Lobke Berkhout, 15th-ranked New Zealanders Susannah Pyatt and Brianna Reynolds-Smith, and 16th-ranked Germans Frederike Loewe and Anna Markfort.

The awarding of the nation qualification berths is subject to final notification from World Sailing, after the event, to the relevant Member National Authority or National Olympic Committee.
