Denmark's Jena Hansen and Katja Salskov-Iversen secured the gold medal in the 49erFX class on the opening day of medal races at the test event for next year's World Sailing Championships in Aarhus.

The Olympic bronze medallists had virtually guaranteed themselves gold with an outstanding performance yesterday but recorded two race wins and a third today to finish on 37 points in total.

Norwegian twin sisters Ragna and Maia Agerup finished a distant second with 75 with Americans Stephanie Roble and Margaret Shea completing the top three on 82.

Austrians Benjamin Bildstein and David Hussl won the men's 49er title.

A first, second and third today saw them finish on 84 points for the event.

Two Australian pairs, William and Sam Phillips and David Gilmour and partner Joel Turner, took second and third respectively on 87 and 103.

The RS:X categories also concluded today.

Lilian de Geus of The Netherlands sealed the women's gold medal.

A second place finish in the medal race was good enough following her domination earlier in the competition as she finished in first place on 19 points.

Italians completed the podium with Marta Maggetti finishing second on 52 and Flavia Tartaglini sealing third on 53.

France's Louis Giard took gold in the men's RS:X.

After finishing second today, Giard completed the competition on 43 points.

Poland's Pawel Tarnowski took second, despite also scoring the same total as Giard.

An eighth place finish in the medal race cost him dear as he was forced to settle for bronze behind Giard.

Kiran Badloe of The Netherlands completed the top three on 47 points.

The event is due to conclude tomorrow with the remaining medal races.

Although it is a test event, the competition is not taking place at the venue due to hold the World Championships next year.

The Aarhus 2018 World Championships will be centred around the brand-new Aarhus International Sailing Centre, located within walking distance from the Danish city.

Action this week is being held on the Egå Marina, just outside the city of Aarhus.
