Sea Scout sailing teams from around the world swap out the boats Friday as new crews take to the water during the 2010 William I. Koch International Sea Scout Cup youth sailing regatta at the U.S. Coast Guard Academy in New London. More than 80 young men and women aged 14 to 21 are competing in the biennial event. The winners will receive a gold medallion and an opportunity to have their names engraved on a silver trophy similar to the original America's Cup. Named after Florida international businessman William "Bill" Koch, the last American to successfully defend the America's Cup, the regatta has revived a youth sailing competition that has been held only once since World War II.
