RedactedNarrative: The operator of Vessel 1 was traveling parallel to the shoreline between the Shedd Aquarium and the Adler Planatarium.  The operator of Vessel 1 stated he was looking at the buildings and people walking along the shore.  The operator of Vessel 1 was looking behind him as he was moving forward.  The pier wall extends further out into the water around the planatarium.  The operator of Vessel one turned his head to look back forward and saw he was going to strike the pier wall, but was unable to react fast enough.  Vessel 1 struck the wall throwing the operator onto the concrete walkway.  The operator got up and put Vessel 1 back into the water and attempted to return to the PWC to the rental facility.  Vessel 1 was damaged  too extensively, and began to take on water.  Bystanders assisted the operator back out of the water and provided medical attention and contacted emergency services.  Chicago Police and Fire Marine Units arrived and provided care.  Operator was transported to Northwestern Hospital for medical evaluation.  The operator was released from the hospital after a few hours with only minor scrapes and bruising.
