Today, the Olympic Women's Single-handed Dinghy, the Lasers Radial, begin their World Championship. 88 participants from 30 nations are on the entry list. With 16 sailors, the host country Japan has the largest delegation. The Olympic Champion and World Cup leader Anna Tunnicliffe USA ist the clear favorite, but a number of opponents will make her life not too easy, such as Paige Railey USA, first of the Europeans a few days ago in her comeback event, or the defending champion Sarah Steyaert FRA, leader of a strong French Team. Interesting to follow also the Olympic medallist and former World Champion Lijia Xu CHN, for the first time in an international race this year. Germany, Austria and Switzerland did not delegate any sailors to Japan. A preview.
