Sailors Annemiek Bekkering and Annette Duetz had a disappointing start to the 49erFX class tournament at the Tokyo Olympics on Tuesday.

The Dutch duo did not get further than thirteenth place in the first race.

Bekkering and Duetz had a mediocre start and managed to gain a number of places in the sequel, but they never managed to get to the front.

The first race was won by the British Charlotte Dobson and Saskia Tidey.

They kept Spain (second) and the United States (third) behind them.

Many countries struggled with the severe weather conditions in Tokyo, where it rained a lot and was windy on Tuesday.

Vice Olympic champion New Zealand's boat even capsized and finished only eighteenth.

In the 49erFX class, the second and third races will follow later on Tuesday.

Bekkering and Duetz finished seventh at the previous Games in Rio de Janeiro in 2016.
