The Delta Flag was raised at 10.41, meaning that racing would start at 11.41. It didn't take the 210 sailors long at all to get out onto the water. The wind was very mild, around 10 knots, but the sun came back out again.
Protests from yesterday's racing had been processed and when the updated provisional results were published, there was a change on the leadership board. Ryan Lo had to give up his third position to Javier Arribas who was previously fourth.
The first fleet started the race at 1208, but all races were abandoned at 1308. The wind was too light for the strong current and sailors were not able to make progress around the course. At 1350 the Race Committee decided to start race 12 again, but at 1427 the very hard call was made to abandon all races for the day which means that the World Championships are over.
The 2011 World Champion Optimist Dinghy Sailing is Kimberly Lim from Singapore.
The provisional leader board (for the individual racing) after 11 races shows: 1 Kimberly Lim (SIN) 70 points, 2 Bart Lambriex (NED) 74 points, 3 Javier Arribas (PER) 77 points, 4 Ryan Lo (SIN) 78 points, 5 Francisco Ducasse (CHI) 87 points, 6 Ahmad Syukri Abdul Aziz (MAS) 90 points, 7 Wade Waddell (USA) 96 points, 8 Gabriel Elstrodt (BRA) 109 points, 9 Rodrigo Luz (BRA) 112 points, 10 Leonard Takahashi-Fry (NZL) 114 points.
