JUSTIN Whithorn and Chris Baldwin from Stroud took part in rounds five and six of the 2010 Zapcat National Championships, held at Leith Docks, Edinburgh.

Whithorn and Baldwin have been racing their twin-hulled semi-inflatable Zapcat for the past two years and this was the team's most successful two days, winning a gold medal on the first day and a silver on th second day, just missing out on first place by a boat's length.

The day's racing consists of six heats and one final.

On the first day, the weather was warm and sunny and racing in the dock, by the Royal Yacht Britannia, was calm.

Team BladeRun won every heat, which put them in pole position in the final. They had a good start and took the lead, which they managed to hold on to.

The second day started off wet and was more changeable, with a strong wind picking up in the afternoon. This made the water choppy and the lightweight Zapcats were susceptible to being lifted into the air by the wind.

This made the races more challenging and not so much about speed. Team BladeRun had some good heats, winning four out of six, putting them in second place on the start line in the final.

The first start of the final was called off after three boats collided on the first corner, even though Team BladeRun was leading.

The team were beaten into the lead in the re-start by their championship rivals, but were chasing hard and on the final straight were only half a boat's length behind them.
