Just recently Team Oracle got caught cheating in America's cup.  This 45" catamaran was owned by Larry Ellison and was caught for adding 5 pounds of weight to the front of their boat making it easier to break through waves.  They caught Team Oracle in a practice race the day before.  These racing boats are very light so the slightest difference changes the race a lot!  The USA team Oracle got docked 2 points, making them win 2 more races than everyone else.  In 2010 the Oracle boat won America's cup just off the coast of South America and are looking for another win this year.
