If wind predictions for Ras Al-Khaimah are correct, that the trimaran can sail at 40 knots, or in 40 knots, is of little consequence. What will matter, says Drummond, is which boat can get up on one hull faster. Traditionally trimarans have had an advantage-due largely to less wetted surface-in very light winds. Once the breeze is such that Alinghi's catamaran can fly a hull, the tables may turn in favor of the lighter catamaran platform. During its inaugural sail, the cat flew a hull in single-digit windspeeds. And, of course, stacking on more sail area could enable both boats to sail on one hull in very light winds. But there is still a lot of time left for development. Both teams are considering hard wing sails, which would be among the biggest fixed airfoil shapes ever produced-the wingspan of a 747 is 212 feet. In fact, given how the most contentious, litigious, and anticipated Cup match has played out thus far, nothing is out of the question.
