David Glenn in Yachting World argue for shutting down the multi-hulls as too fast, too dangerous. But Glenn misstates several facts. The reason for the multihulls was not some ""idea" that Oracle had. It grew out of a classic America's Cup of AC33, run by the basic unlimited rules of the America's Cup. Any AC run by those rules will be in a multihull because it will always beat a monohull. As for TV causing the problem, not the case. TV affected the race course, making it shorter and closer to land, but the technology of sailing and the nearly unlimited design rule of the America's Cup dictated the multihulls. Again, AC33 demonstrates what a classic America's Cup looks like in the 21st century when wealthy individuals compete with unlimited technology and unlimited resources. A race in big fast multihulls, powerful but fragile boats at the edge of technology. If the America's Cup is going to be the pinnacle of sail boat racing, unlimited technology and unlimited budgets, it will be in 100 foot multihulls. Sailing the America's Cup in purposely slow, old technology is what "ripped the heart out" of the America's Cup. As for danger, as dangerous as OneAustralia breaking in half and sinking. Fortunate no one was killed there, unfortunate Simpson was killed here, but the risk was the same. Boats pushing the edge for every speed advantage. A flawed boat design is dangerous no matter what the boat. That too has always been a feature of the America's Cup. The boats are changing daily up until the last possible moment. Had Conner known of the winged keel of Australia II, he would have been working day and night to redesign the defender, Liberty.
