Xu steals the show
Lijia Xu stole the show on the second day of the Sail for Gold Regatta at the Weymouth and Portland National Sailing Academy.
Xu, China's first ever Olympic sailing gold medallist, won four races ahead of team-mate Dongshuang Zhang in the Laser Radial class.
Britain's Alison Young was their strongest competition after recording two fourth places and two third places in Monday's breezy conditions.
In the Nacra 17 class, the new multi-hull class for the Rio Games in 2016, Britain hold the top four places, with Ben Sexton and Hannah Diamond holding the overall lead after overhauling Sunday's leaders Lucy Macgregor and Tom Phipps on count back.
Diamond said: "We hadn't realised we'd taken the lead, but that's nice to know.
"The first race went right down to the finish line so it was really nice to win that race. It was still pretty light winds which is still something we've not done that much racing in so it was really good practice for the Worlds.
"It's been pretty up and down and all over the place so it's good to have a solid day."
New Zealand's Sam Meech has the advantage over Holland's Nicholas Heiner and Argentina's Julio Alsogaray in the Laser class, with Britain's Nick Thompson fifth.
The Finn fleet, made up of an entirely British entry, is led by Mark Andrews, with Andrew Mills in second, while John Pink and Simon Wheeler extended their advantage in the 49er class by nine points over Japan's Yukio Makino and Kenji Takahashi.
Olympic medallist Nick Dempsey is second to compatriot Elliott Carney in the RS:X 9.5 category, while Bryony Shaw holds the edge in the RS:X 8.5 field.
Paralympic gold medallist Helena Lucas is another Briton making the most of home advantage, she leads Megan Pascoe by a single point in a close-fought 2.4mR battle.
