No skipper was given Minoprio's luck forcing them to relentlessly pursue every possible advantage. A pre-start incident between triple Olympic gold medallist Ben Ainslie (GBR) TEAMORIGIN and Bjorn Hansen (SWE) Hansen Global Team saw the umpires find in favour of the British team, as Ainslie explains: "It was a 50-50 situation in which we had to keep clear when Hansen luffed us hard. It was a difficult decision for the jury as to whether he had been too aggressive, or whether our response was too slow. Luckily they decided in our favour."
Next up was a French derby between Damien Iehl (FRA) French Match Racing Team against Bertrand Pacé (FRA) Aleph Sailing Team. There was no love lost though as Richard tried to pin Pacé outside the line at the start. In a super-close rounding of the second mark, Richard had the favoured inside line, while Pacé collected a penalty for failing to give him space giving Richard the advantage which he held to the finish.
In what proved to be the final chapter of the day, Ainslie held a big lead over Hansen when a wind shift of such magnitude made it difficult for Hansen to hold the spinnaker. Despite vehement protest from Hansen's team, the race was not abandoned giving Ainslie a second and decisive win to join Ian Williams (GBR) Team GAC Pindar in the semi-finals.
The battle between the two wind systems continued through the afternoon, and despite supreme efforts by the race committee, racing eventually had to be abandoned for the day. The remaining quarter-final races to decide the two teams that will face Ainslie and Williams in the semi-finals, will take place at 1000 local time Sunday morning.
