A lack of wind has meant a reduced schedule at the Weymouth & Portland National Sailing Academy this week, but Nacra 17 sailor Saxton has capitalised whenever he has been out on the water - and did so again on Saturday.Alongside partner Nicola Groves, the Huntingdon sailor dominated the field recording comfortable victories in the two races completed to surge to the top of the overall standings, seven points ahead of German duo Paul Kohlhoff and Carolina Werner.That is a healthy advantage for the British pair to take into the medal race but Saxton claims it would be dangerous to change their approach now.I dont think you can be a bit more defensive even when youre leading going into the medal race, he explained.If we sail a good race we win the regatta which is the best thing about being in the lead on the final day.Everything is under our control and this is going to be great practice for the Rio Olympics because that will be a small fleet like this.Weve sailed a great few days but were not too far ahead of the other guys so hats off to them for still being there. Now we have a good chance to practise staying ahead of the field.Sundays sailing consists of a sole medal race, worth double points, with the winners being the pair atop the overall standings at the conclusion of that race.Saxtons fellow Huntingdon man, Giles Scott, is another sailer sitting top of the leaderboard heading into today.Scott boasts a one-point cushion over rival Ben Cornish in the Finn class after winning the only race of yesterday.But with the weather having played havoc with racing all week, Scott insists it is still all to play for.With so many people able to medal it effectively turns it back into a normal fleet race with you keeping half an eye on certain sailors, he said. Its an odd situation to be in.Were even closer than I thought we would be with the small fleet and it sort of feels like the regatta is only just getting going and were in to the medal race.Its a little bit strange to have a regatta with only five races and it just puts massive emphasis on the medal race tomorrow with 20 points up for grabs.Tickets for the Sailing World Cup Weymouth and Portland, to be held at the Weymouth and Portland National Sailing Academy from 6-12 June, are available at www.rya.org.uk/go/swcgb.
