Sailing action in the first four flights of the day saw strong performances from Lucy Macgregor (GBR) and her crew, with clear wins in three out of four matches, beaten only by Australian teenager Olivia Price and her crew.
"We're pretty happy with today, we raced five races, won three and lost two," said Price. "In the races that we lost it was just unfortunate errors that we made ourselves. We came back each race to fight hard and we're really happy with our performance today."
The two teams from Netherlands found themselves going head to head in Group B.
Renee Groeneveld (NED) and Mandy Mulder (NED) had each recorded three wins, but up against each other, it was Groeneveld and her crew who crossed the line two boat lengths ahead.
Group B sailors first encountered gusty easterly winds up to 15 knots, but a short-lived wind change at midday forced a course change-over. As a result, the final match, between the two Spanish teams, was postponed to the second day of Group B racing on Tuesday.
The forecast sea breeze failed to arrive in time for Price to open up a gap on Silvia Roca (ESP). Neither team flew a spinnaker as they crawled down the last leg of the course with very little pace until the last few metres, when Price saw her chance and cut in ahead of Roca, winning the match.
Poor wind conditions continued into the afternoon which saw racing grind to a halt as the course was arranged and rearranged in an attempt to accommodate the changes.
Taking to the water for flight 32, was the second group of Elliot 6m crews. However, the sailors competed more against the dying wind and tidal flow than against each other.
In flight 33, France and Croatia struggled to gain momentum in match 1 as the famous Fremantle Doctor still failed to appear.
With an almost non-existent breeze, ISAF officials decided that would be the last race of the day, postponing the days remaining flights until 6 December, when Group B is next scheduled to compete.
Women's Match Racing commences at 10:00 local time tomorrow with the Laser Radial the first fleet to receive their warning signal at 12:00 local time. The Women's RS:X and Men's 470 follow at 12:30. The Finn fleet start at 13:00.
