"Artemis Racing have made a massive jump in the last two or three weeks"
- Russell Coutts
The five America’s Cup teams in Bermuda held the second series of test races in their America’s Cup Class race boats – 17 races in all. In windy conditions Artemis dominated, winning all nine races, including four against Oracle. Oracle beat everyone else, including three wins against stablemates SoftBank Team Japan. Team Japan lost five races but beat Land Rover BAR and Groupama Team France once each. BAR raced each team once, beating only the French. France raced each team once, losing to everyone.
But... All of the teams will continue improving!
France has good straightline speed but are still mastering their boat and the control systems.
BAR has great crew work on a slow boat that they will continue to develop.
Team Japan, like the French, has a fast boat and will continue to improve.
Oracle has heaps of resources and experience at making a comeback.
Artemis will keep getting faster.
And we will probably see the newly-arrived-inBermuda Kiwis in the next series of practice races, 24-28 April.

As head of the design team for Emirates Team New Zealand for the 2013 America's Cup, Nick Holroyd helped lead the surprise move to foiling. Now with SoftBank Team Japan, Nick's design work helps make sure Team Japan will have a fast boat. This is a really good video that explains the tradeoffs in designing winning foils, and the new way that the rudders are being used. Click the photo to see the video.
Rudder rake differential adds righting moment with downforce from windward rudder's horizontal stabilizer.
Looking for every possible advantage in the America’s Cup, Oracle Team USA has a small scale wind model for Bermuda’s Great Sound. Technical partner Airbus built the model for them using large quantities of wind data the team has collected over the last two years from their test boats, chase boats and the crane at their base. Large scale models for the Atlantic cannot be scaled down into reliable models for the Great Sound, since it is enclosed and subject local effects unrelated to the rest of the Atlantic.
