RS500 INLAND CHAMPIONSHIPS 2013
See the results and report here.
The event was held down the road at Queen Mary RSC.
They were in 2nd place after day one, and scored three wins out of three on day two to take the series by a couple of points.
There's a report here and some photographs on the website http://www.sportography.tv/, of which I think this one and this one are probably the best.
