Seven young windsurfers plus coach are heading over to San Francisco this week for the 2011 Techno 293 World Championships. Based at the St Francis Yacht Club, directly in front of the Golden Gate bridge, the event runs from 17 to 24 July. The kiwi sailors, four boys and three girls, are all in their mid-teens, and come from sailing clubs in Whangaparaoa, Auckland, Tauranga and Christchurch. Their coach, Kate Ellingham from Devonport, is a former NZ number one in the Olympic RS:X class.
