Seven rounds into the 2013 America's Cup, and the sailors, designers, and engineers of the defending champions, Oracle Team USA, had a problem. As The Wall Street Journal explains, the sailing club had lost six of seven boat races in the illustrious, 160-year-old competition to its opponent, Emirates Team New Zealand. Oracle Team USA — better funded, fielding a more advanced craft, but still losing — had to go back to the drawing board, going against sailing wisdom and overhauling advanced computer models in an attempt to claw back the advantage. The result, as detailed by The Wall Street Journal, became one of the greatest comebacks in sporting history.
