It's anchors away for the annual Chicago-to-Mackinac Island race.

More than 350 yachts set sail in a 24-hour sprint to the Michigan Island.

The race started Saturday morning with boats parading by onlookers at Chicago's Navy Pier.

Teams have been sailing all day and will continue overnight before finishing the 333-mile course.

Dating back to 1898, Mackinac is the oldest annual freshwater distance race in the world.
