Ainslie happy with his seconds - London 2012 - Sailing
Three-time gold medallist Ben Ainslie struck a satisfied figure after securing second-place finishes in the opening two Sailing Finn races.
He finished the day with two second places behind Denmark's Jonas Hogh-Christensen.
'It was a good day,' he said. 'They were tough conditions out there, especially on the Nothe Course [in the first race].
'There were very, very shifty winds but it was a good start. It was ok, but there is a long way to go.'
The opening races both finished with the same top three of Croatia's Ivan Kljakovic Gaspic then Ainslie in second and Hogh-Christensen.
The Dane was pleased with his performance but keen to stress this it is only the beginning of the regatta.
'It was a great day, but Ben and Ivan are close behind and we're very early in the regatta,' Hogh-Christensen said. 'I need to keep cool, take it one day at a time and focus on tomorrow.'
The other men's class to start on Day 2 of the Games was the Star and saw British pair Iain Percy and Andrew Simpson recover from a difficult start to end the day in fifth overall.
The reigning Star gold medallists endured a poor first race in which they ended 11th, but responded superbly to end the day's final race in the top two - behind race winners Robert Scheidt and Bruno Prada from Brazil.
