The U.S. Coast Guard is investigating why a Channel Cat boat slammed into a pier while it was trying to dock in Bettendorf, sending two children to the hospital Saturday. 

Another 12 people suffered minor injuries. 

Coast Guard spokesman Jerad Landheer said the initial 911 call for the injured children went out at 4:41 p.m.

The Channel Cat 2 was attempting to dock at the Isle of Capri when it slammed into the pier, he said. 

Landheer said Coast Guard boats were nearby policing the Mississippi River and responded to the call as did the Iowa Department of Natural Resources, Bettendorf Fire Department, and MedicEMS. 

“One of the children suffered a laceration to the face, while the other child suffered a head injury and reportedly lost consciousness for a short time,” Landheer said.

The children were taken to Genesis Medical Center-East Rusholme Street, Davenport, for treatment. Their conditions were not available Saturday night.

“There were multiple people, up to 12, who suffered bruises, contusions and lacerations,” Landheer said. Those people refused treatment at the scene, he added, but the victims did indicate they would visit the emergency room or a doctor on their own.

Bettendorf Fire Department Lt. Jeff Green said those passengers' injuries were minor and included bumps and bruises to knees when they struck railings inside the craft. 

Landheer said the Channel Cat 2 was not damaged. 

“We’ve inspected it and the vessel is structurally sound,” he said. However, it was parked while those riding the vessel either continued on the river tour on Channel Cat 1 or went on their way, he added.

Landheer said the Coast Guard investigation will include drug and alcohol testing of the pilot.

The Channel Cat boats are owned by MetroLINK, and are operated by the Celebration Belle, said Jennifer Garrity, manager of administration at MetroLINK.

A spokesperson for the Celebration Belle was not available for comment Saturday night.
