The traditional sea breeze of summer at Sydney arrived on the third day with the morning classes of the Olympic classes taking place in the north-north easterly breezes with 12-14 knots. The flying of the afternoon session was in 16-22 knots out of the northeastern at Nacra 17 course.

Lisa Darmanin and Jason Waterhouse from the Australian Sailing Team tore the Nacra 17 mainsail in a horizontal manner during the 2nd race of the 3rd day. This prompted a dash from the Sow and Pigs area of reef course to the Harbour Yacht Club in one coach boat for retrieving the spare. Darmanin has stated this was Rio edition sail and according to her, these things are common. She said that she jumped with Darren Bundock and together they hightailed it ashore. They have been lucky that there was a spare. They struggled to get the battens inside and they had been ready to go twenty seconds prior to the starting of the third race.
