RedactedNarrative: On 819118 at 2258hrs. I was notified by Lorain Police OIC Lt. Cornwell that a boat had struck an unknown object in the area of Lorain Harbor, and that the lone occupant was being transported via Life,Care for treatment. Based on this information I responded to Mercy Hospital prior to going to the scene. Once at the hospital I learned that the operator/owner, he sustained a head injmy during the accident which necessitated he be flown to Metro Hospital in Cleveland for further treatment. As such he was being prepared for flight, and I was unable to speak with him. 
  Based on the severity of injury I contacted Lt. of ODNR Parks and Watercraft who advised he would send Investigator to Metro Hospital to conduct an interview (sec attached Investigatory report 18NR0006396). 
  
  I then went to the above listed vessel which was lefl moored at Spitzer Marina gas dock. A check of the vessel revealed that the damage sustained, while severe, was well above the water line, and it was in no danger of sinking. The damage sustained indicated that the boat struck an almost vertical surface ruling out a rock break wall, or smaller recreational vessel. 
  
  Because the operator was incapacitated, and the vessel left at the gas dock unsecured, I along with Dep. took the vessel in side tow with the Lorain Marine Patrol boat, towed it to our secure dock, and moored it there until the owner could make arrangements to retrieve it. 
  
  The next day, 8/10118 I, along with Dep. began checking the vertical surfaces in and around Lorain Harbor for signs of impact. In doing so I located a fresh impact mark on the Eastern Detached wall protecting Lorain Harbor, on the outside of bunk# l 0, at the coordinates recorded above. It should be noted that this mark was high on the wall, and corresponds perfectly with the statement given by Operator/owner to 
  Investigator in which he stated he was using the "light house" (assumedly Old Main) as a reference to guide him to the mouth of the Black River. Photos of the strike mark, as well as photos of the damage to the vessel were taken, and later downloaded to the OIC photos file. 
  
  On 8/12/2018 l met with the Operator/owner who explained that be was returning to Lorain Harbor, and running parallel to the steel break wall when the vessel struck an unknown object in the water, the Operator/owner states this unknown object pushed to vessel toward/ into the break wall causing the strike.
  
  Based on the above Operator/owner was issued citation number or action to avoid collision, as his failure to maintain proper lookout, maintain proper distance from a fixed wall, and make the proper course correction, was deemed the cause of the accident.
