Virtual Eye: Race 2 Breakpoints - 33rd America's Cup
|
With the help of Virtual Eye, Sail-World's America's Cup editor, Richard Gladwell looks at the key points of Race 2, of the 33rd America's Cup, and some of the performance differences between USA-17 and Alinghi 5
Above: After being caught outside her prescribed area in the prestart of Race 2, due to an on-board timing error, Alinghi opted for a split tack start heading for the right hand side of the course. USA-17 too the pin end and started with a 112metre advantage.
After 11 minutes, USA-17 had stretched this into an 600 metre lead, before Alinghi picked up the sniff of a right hand shift and tacked.
Just four minutes later they were almost even, but on opposite tacks.
Another four minutes and USA-17 had conceded the advantage to Alinghi 5, had tacked underneath and the margin had now stretched to 600 metres in favour of Alinghi.
USA-17 picked up after the shift stopped working to Alinghi's advantage, with the Challenger electing to tack just short of the layline, while Alinghi overstood by some 100 metres.
By the time Alinghi had tacked, USA-17 was almost up to the layline, however there was not a lot in it in terms of margin.
As USA-17 eased up an over the layline, she accelerated and stretched her lead on Alinghi 5
At the first mark, USA-17 had stretched her lead to over 300 metres.
At the second mark, and 13 miles sailing USA-17's margin had stretched to 2100metres.
As she gybed for the finish, having sailed at speeds over over 20kts for much of the leg USA-17's margin had now stretched to almost 3,000 metres, interestingly having held good boatspeed during her speed dropped to just 7kts soon after the gybe.
At the finish, Alinghi, before her final gybe was 1225nm behind USA-17 underlining the patchiness of the breeze, as night fell.
