America's Cup - San Diego - The dismasting last week has forced BMW Oracle Racing to speed up transactions in the formal laying of the new, futuristic, rigid wing that the U.S. team has in mind to use ahead of next February's match against Alinghi 5. This is something very similar to that used on boats born to break records for speed, as Macquarie Yellow Pages.
Made at the premises of Anacortes, the wing was assembled in San Diego: "It was a titanic - Tim Smyth said that, along with Mark Turner, designed the wing BOR 90 - No one ever before of us had built a wing of this size and we are proud to have completed the work. "
One wing of the genre, in fact, had never seen in the world of races: in terms of size far exceeds that of a modern airplane. Almost 57 meters high on the deck, is large eighty per cent more than those of a Boeing 747.
The main advantage of a rigid wing sail with respect to a common carbon is the perfection of form and ease of control. In practice, the edge is less trouble to fit the shape of proilo to changing weather conditions.
Initial tests in water are expected for the weekend, when the team resumed training ahead of the match set for next February against Alinghi.

AMERICA'S CUP, THE WING
America's Cup - San Diego - The latest development by the BMW Oracle Racing team was unveiled today when an enormous wing was prepared to be wheeled out of the tent at the team base in San Diego. The wing will be tested as an option to increase performance compared with a traditional soft sail rig as previously sea trialed on the BOR-90, the 90-foot trimaran has built the team for the 33rd America's Cup
The construction of the wing took place at Core Builders, the team's boatbuilding facility in Anacortes, Washington, with finishing work completed at the team base in San Diego.
"This was a massive undertaking - said Tim Smyth (NZL), who, along with Mark Turner (NZL), has been Overseeing the wing construction team in Anacortes and in San Diego - Building a wing of this size was something new for all of us, and we're proud our guys were Able to Rise to the challenge.
A wing of this scale has never been built for a race boat. In terms of size, the wing on BOR 90 dwarfs those on modern aircraft. Towering nearly 190 ft (57 m) above the deck, it is 80 percent bigger than a wing on a 747 airplane (102 ft/31 m).
The primary advantage of the wing over a soft sail is that it is easier to control and does not distorted. This makes it easier for the trimmers on board to maintain an optimum aerofoil shape in a wide range of conditions.
Full-scale, on-the-water testing of the wing will begin later this week as the team resumes sea trials in preparation for the 33rd America's Cup Match in February.
