Their pair of victories saw them rise above Linda Fahrni and Maja Siegenthaler into first place with six points, while their Swiss rivals are second on a total of eight.

"We had good boat speed in the first race and from there we just tried to defend the lead and stay in front of the fleet which we did well," said Van Veen, who missed out on an Olympic medal with Zegers after ending fourth at Rio 2016.

"In the second race, we had a really good start from the pin and got the lead straight from that.

"We just played the shifts then."
