CHICAGO (CBS) — Eight people are recovering, after their boat hit a break wall in Lake Michigan, offshore from the old U.S. Steel plant grounds.

The group was heading home to a marina in Hammond, Ind., from a ride up the lake to the Chicago River, when the boat hit a break wall offshore from 85th Street and Green Bay Avenue, according to the U.S. Coast Guard.

The boat was carrying six adults and five children when it hit the break wall about 10:45 p.m. Sunday, according to Fire Media Affairs and the Coast Guard official.

Eight people aboard were taken to area hospitals with non-life-threatening injuries, including a child sent to University of Chicago’s Comer Children’s Hospital in fair-to-serious condition, according to Fire Media Affairs.

Two adults were also taken to Advocate Christ Medical Center in Oak Lawn in serious-to-critical condition, two adults were taken to Advocate Trinity Hospital in fair-to-serious condition and two were taken to University of Chicago Hospitals in good condition.

One of the adults taken to Trinity was a woman complaining of back pain, the Coast Guard search and rescue controller said.

Three people refused medical attention, according to Fire Media Affairs.

Lack of experience by the boat operator and night conditions may have played a role in the accident, the Coast Guard search and rescue controller said.
