Nacra sailors Jason Saunders and Gemma Jones are the early pacesetters in the Rio sailing test event for the new Nacra 17 class.
The pair had two second placings in the first two races to sit top of their event.
However the day didn't go entirely to plan with Saunders taking an unscheduled dunk in their third race, when they finished 15th.
''We had a little problem after the start and I fell off the trapeze and into the water, so we were a bit behind from there and it was pretty hard to catch up," Saunders said.
"We sailed really well in the first two races, we had two great starts and sailed the shifts well. It was tough out there with the sea breeze but we managed to sail the conditions really well."
