Crash helmets, personal floatation devices and other body armor have been de rigueur during BMW ORACLE Racing’s practices—even while using a mast and a mainsail, which preceded the wing. During a practice session on November 3, the boat’s huge mast snapped and toppled into the Pacific. Thankfully, no one was injured. Although the team’s research and development unit has been conducting a forensic evaluation of the mast mishap, another unit has been finishing the assembly of the wing under the cover of a huge tent at the team’s base in San Diego, in an attempt to keep the technology a secret from competitors…
