By Aaron Kuriloff Dec. 15 (Bloomberg) — The America’s Cup boats that will race in February — products of a technological showdown between billionaire sailors — may bring wings, multiple hulls and computers to the next generation of sailboats. The two-year legal battle between billionaires Larry Ellison and Ernesto Bertarelli has produced two racing yachts that are a decade ahead of any boat built previously, even as it has dogged and delayed the 158-year-old regatta, to be held off the coast of Spain. The innovations made as longstanding Cup rules were abandoned in the search for a settlement may one day benefit sailors on weekend jaunts. Designers for both Ellison’s BMW-Oracle Racing and Bertarelli’s Alinghi syndicate said building and learning to sail these boats, each at least 90 feet long and among the fastest yachts ever built, has meant gains in everything from data collection to sail technology. “We’re like kids in the candy shop,” said Dirk Kramers, chief engineer for the Cup-defending Alinghi catamaran. “During the last Cup , it was all about trying to squeeze another 1/100th of a knot out of the boat. Now we’re really in discovery mode, learning huge lessons every day. We get to work on boats that are just so much more exciting than anything that’s ever been done.” Sailors, recreational boaters or other users of ultralight, aerodynamic technologies may benefit in coming years from equipment and data being assembled by both the Alinghi and BMW- Oracle racing syndicates, said Pete Melvin, a U.S. Olympic sailor and world champion . Development Jump “It’s been a hugely concentrated development, with all the best people in the industry, plus outside experts in every field, all focused on pushing the edge of the envelope,” said Melvin, co-founder of Morrelli & Melvin Design & Engineering Inc. . “It normally would have taken eight or 10 years to do what’s been done in just two short years.” Morelli & Melvin has designed multihulls, including Steve Fossett’s record-setting Playstation , and has consulted for BMW- Oracle. Multihulls are much faster than monohull boats, because they are lighter and have less drag. The America’s Cup has long featured yachting’s cutting edge. The 1983 victor, Australia II , used wings on its keel to reduce drag and increase performance. Such wings, so secret at the time that it took two undercover frogmen to spot them, are now common on sailboats worldwide. Recent editions of the Cup required boats that were restrictive and boring, says Donnie Brennan, boatwright for the U.S. Olympic sailing team in Beijing and owner of Mobile, Alabama-based Diversified Marine Services Inc. Two years of lawsuits over the rules of the event have led to an anything- goes faceoff that “certainly opens the door to innovation and technology,” he said. ‘Kazilllions of Dollars’ “They’re charting new areas,” said Brennan. “It’s great that we’ve got someone like Larry Ellison out there dumping kazillions of dollars into this technology.” Bertarelli spent about $90 million to capture the Cup from New Zealand in 2003. Grant Simmer, Alinghi’s design team coordinator, told Seahorse magazine that the team’s catamaran cost about five times as much as a typical Cup boat. Representatives of both teams declined to discuss the details of their biggest advances, saying they wanted to hide them from each other. Alinghi said in a New York court filing that Ellison had hired spies to sneak looks at its catamaran. Mike Drummond, design chief for the BMW-Oracle trimaran, said he can’t conceal the 190-foot wing that this month replaced a sail on his boat. The carbon-fiber foil is bigger than the wing of an Airbus A380 , the world’s largest passenger jet. The 60-foot Stars & Stripes catamaran that defended the America’s Cup in 1988 used a wing that was about half the size. A wing is more efficient than a conventional sail, holding its shape better while generating increased lift and diminished drag. High Risks It’s also harder to control, Drummond said. “It is an unknown risk for us,” he said. “We decided that the potential gains were enough that we would take that risk.” Drummond called some recent small breakage “teething problems” and said that the team was working to solve them while processing “more e-mails than the moon landing” full of questions from excited sailors. Alinghi also has considered wing technology, Kramers said in an interview. Designers also have worked on new kinds of line to handle the excess loads and, for the first time in the America’s Cup, onboard engines to power winches and other systems. On-Board Cameras Other likely spots for technological advancement include some of the most concentrated data collection in sailing history. Both teams use fiberoptic systems and on-board cameras to measure things like sail shape and stress. Kramers said sailors would find uses for both the data and the collection systems. In the meantime, he cautioned against celebrating either design until the two boats meet off Valencia. “It’s not a game about who comes up with the fanciest toys — you’ve still got to win a boat race,” Kramers said. “You can shoot yourself in the foot quite easily. You can make it too light and have something break on you, or you come up with something so complex you don’t know how to sail it. So there’s a certain amount of restraint involved, too.” To contact the reporter on this story: Aaron Kuriloff in New York at akuriloff@bloomberg.net .
