Dorian van Rijsselberge of the Netherlands and Marina Alabau Neira of Spain were both one-sided gold medal winners Tuesday in Olympic windsurfing. Both had massive leads going into Tuesday\'s medal races off the southern coast of England. Alabau Neira won gold after finishing fourth in the women\'s race in 2008. Van Rijsselberge finished with 15 points after winning six of the 10 preliminary races in the competition and finishing second in two others. He also won Tuesday\'s medal race, in which only the top 10 sailors from the prelims compete. Nick Dempsey of Britain was second overall, taking the silver medal with 41 points. Przemyslaw Miarczynski of Poland jumped from fourth to third in the medal race to capture the bronze. Toni Wilhelm of Germany began the day in third place but fell to fourth after a ninth-place finish in the medal race. Although Alabau Neira had an easy win in the women\'s event, the other two medals were very much in doubt during the medal race. Tuuli Petaja of Finland earned the silver medal by a single point over Poland\'s Zofia Noceti-Klepacka. Ukraine\'s Olha Maslivets had the lead in the medal race heading to the next-to-last mark and if she could have held that advantage she would have rallied for a bronze medal. Instead, she was passed by Alabau Neira and wound up second in the race. That left her one point behind the Polish bronze medal winner.
