It proved to be unimportant, as the wind drop as most of the fleet were on the second upwind and the Race Committee abandoned the race. The Finns waited for another hour and a half but conditions didn't improve and they returned to shore shortly before 16:00.
The Finn Medal Race has been rescheduled for Sunday at 14:00 local time.
"It was very frustrating to me," said AINSLIE back onshore. "I thought to myself, the conditions are very unpredictable, so I just have to cope with it the best I can."
Looking ahead to tomorrow, it appears unlikely the Briton will change his tactics. "At the end of the race that was abandoned, Zach and I had a little gentlemanly chat," AINSLIE revealed. "He mentioned that he would like a silver or bronze medal, and I said to him, 'This is the Olympics, and I can't take any chances."'
RAILEY said a mistake at the start had cost him dearly, "I had a good start but heard a horn blown from the Committee boat. I thought it was an individual recall, but it turned out to be a mistake. So I gybed back and restarted. That's how he [AINSLIE] got ahead of me and was able to do what he did to me."
Ahead of tomorrow's race he added. "I'll do my best next time not to let it happen again."
