Notes on the wing
The wing sail consists of two main components: the main element and the flap element. The main element is one single piece that rotates around the mast step. Nine flaps rotate around the trailing edge of the main element. Both elements are separated by a small gap and linked together by hinges.
The wing sail is primarily constructed from carbon fibre and kevlar with a light, shrinkable aeronautical film material used as an overall skin over the frame.
According to Joseph Ozanne, an aeronautical specialist with the BMW ORACLE Racing design team, the ability to trim the wing sail easily is one of its big advantages over a soft sail.
"With a soft sail, it's so big, it's difficult to shape as you only have control over three points (head, tack, clew). You need massive tension to trim the soft sail," he says. "With a wing sail, you can get the shape you want much more easily."
The main trim parameters are: master wing rotation (similar to mast rotation on a conventional rig); master camber control (general rotation of the flap element); flap twist control (each flap can have a specific angle of rotation).
"On paper, it's a clear advantage over the soft sail," Ozanne says. "It’s on such a different scale to what has been done before, it was hard not to have some uncertainty. But we are more and more confident... I think it's going to be a strong addition for us."
The team’s boat construction managers were pleased to see the latest build project on its way to San Diego.
“Our Anacortes crew have been a vital part of our last two America’s Cup campaigns,” said Tim Smyth (NZL), who, along with Mark Turner (NZL), has been overseeing the boat-building project for the team.
“For this campaign, and with this boat, we’ve been building on a scale that hasn’t been attempted in the modern America’s Cup,” Smyth said. “For all of us, this has been a big test of our skills and ability, and the team here in Anacortes has more than responded to the challenge. I’m very proud of what’s being accomplished here.
While boatbuilding activity has increased in San Diego with the latest BOR 90 modifications, the Core Builders facility in Anacortes remains the backbone of the team’s American construction operations. The team in Anacortes will continue to work on America’s Cup-related projects."
"BMW ORACLE Racing, the American team hosted by the Golden Gate Yacht Club, was the only challenger in the 33rd Cup race and the first American boat to reach challenger status since the San Diego team lost to New Zealand in 1995.
The team raced USA 17, a trimaran 90 feet long on the water, 113 feet overall, with a metallic "wing" sail instead of a conventional fabric mainsail.
The captain of the American team was Russell Coutts. Born in 1962 in New Zealand, Coutts had skippered the winning Cup boat in three of the last four Cup series: winning in 2003 for Alinghi and in 1995 and 2000 for Team New Zealand. Australian Jimmy Spithill, age 30, was at the helm of USA 17. Larry Ellison, CEO of Oracle Corp., was the primary funder and driving force behind the American team."
