This has resulted in boats that do not perform identically on all points of sail, which opens up another match racing tactic of forcing the opponent onto an unfavored point of sail. During the 2003 America's Cup Challenger Series between Oracle BMW Racing and Alinghi, for example, the Alinghi boat was heavier but more powerful and favored on higher points of sail downwind. Alinghi used the tactic of getting to leeward of Oracle on a downwind leg and forcing her up onto a course where Alinghi was comparatively faster, although Alinghi herself could have sailed faster to the finish line on a lower course.
