TRIMARAN AC72 ( USA 17).33th America´s Cup.

[Miguel Gil]

USA-17 (formerly known as BMW Oracle Racing 90 or BOR90) is a sloop rigged racing trimaran built by the American sailing team BMW Oracle Racing to challenge for the 2010 America's Cup. Designed by VPLP Yacht Design with consultation from Franck Cammas and his Groupama multi-hull sailing team, BOR90 is very light for her size being constructed almost entirely out of carbon fiber and epoxy resin, and exhibits very high performance being able to sail at 2.0 to 2.5 times the true wind speed. From the actual performance of the boat during the 2010 America's Cup races, it can be seen that she could achieve a velocity made good upwind of over twice the wind speed and downwind of over 2.5 times the wind speed. She can apparently sail at 20 degrees off the apparent wind. The boat sails so fast downwind that the apparent wind she generates is only 5-6 degrees different from that when she is racing upwind; that is, the boat is always sailing upwind with respect to the apparent wind. 
The 33rd America's Cup between Société Nautique de Genève defending with team Alinghi against Golden Gate Yacht Club, and their racing team BMW Oracle Racing was the subject of extensive court action and litigation, surpassing in acrimony even the controversial 1988 America's Cup. Since the two parties were unable to agree otherwise, the match took place as a one-on-one deed of gift match  in gigantic, specialized multi-hull racing yachts with no other clubs or teams participating. The Golden Gate Yacht Club swept the two races as their yacht USA 17 powered by a rigid wing-sail proved to be significantly faster than Société Nautique de Genève's yacht Alinghi 5. The litigation leading up to the match included which club would be the challenger, the dates and venue for the regattas, certain rules governing the regattas (in particular the measurement rules), and the construction of the boats.
It was held for the second time on the coast of Valencia (Spain).
The Americans won back the Cup after they last lost it in 1995.
