New summit America's Cup in performance
A new summit has been reached in the America's Cup performance quest with defenders Oracle joining Team New Zealand with their ability to foil up wind.
Video footage of Oracle up on its foils heading into the breeze emerged from San Francisco yesterday and it was an impressive sight in practice.
Not to be outdone Team New Zealand pulled off what was previously judged "seemingly impossible" during their ill-fated second race with Luna Rossa yesterday in the Louis Vuitton Cup final series.
Heading up wind on the third leg, the Kiwis showed glimpses of their new foiling trick - lifting their leeward hull out of the water and thus reducing the drag factor to increase their speed.
What was more impressive was that Team New Zealand appeared to be achieving it without losing any of their direct angle to the next mark.
Perfecting this is now obviously going to be crucial to the challenging syndicate for next month's America's Cup match given that Oracle are openly showing that ability and will work overtime to fine-tune it.
The skill is certain to feature in the battle for the Auld Mug.
There is only one upwind leg in the five-leg course used for the racing - but it is the most time consuming and anything that can be achieved to eat into that time will be crucial.
