Great Britain's Sophie Weguelin and Eilidh McIntyre took control of the women's 470 fleet at sailing's ISAF World Cup in Miami.
The partnership combined to pick up two race wins and almost snatched a third until a late penalty, meaning they enjoy an eight point advantage over their rivals with two days of racing still to come.
“Our goals coming here were to work on our communication and our decision making so actually these [light wind] conditions have been really perfect for it," said McIntyre.
"We’ve been doing really well, the tempo has been good in the boat and we’re really pleased.
“It’s not usually our preferred condition so it’s quite nice to have found a new strength and we’ve been working on that over the past couple of days."
The new British 49er pairing of John Pink and Stuart Bithell also lead their class while windsurfer Bryony Shaw enjoys an eight point advantage over her nearest rivals.
Also well placed for a strike at the podium is Finn sailors Giles Scott and Ben Saxton and Hannah Diamond in the Nacra 17 multihull class.
