RedactedNarrative: On, Thursday, March 13, 2014, at approximately 2245 hrs, I responded to a vessel accident approximately one half mile south of Rickenbacker Causeway. I identified the operator of V1. Operator1 stated he was traveling westbound at approximately 20 mph and struck a vessel with no lights on. V1 struck vessel two's starboard midship hull. The operator of V2 was taken and treated at Mercy Hospital. V2 was anchored in the bay and had his navigation and anchor lights switch in the off position.  At Mercy hospital I identified owner and operator of vessel two.  Operator2 stated while he was eating in the cabin of his vessel, a vessel struck his boat and the roof collapsed on his head. Operator2 received a small laceration to the left side of his forehead and received stitches. Operator2 was issued a citation for no anchor lights on.  I obtained a sworn written statement from Operator1 and photographs which are included in this report. Both parties were given a case card with the offense number.
  
  In conclusion, V1 was traveling westbound approximately 1/2 mile south of Rickenbacker Causeway. V2 was anchored in the same approximate location with no lights on. V1 struck V2's starboard midship hull. V2's operator received a small laceration to the forehead. V2's operator was transported and treated at Mercy hospital. The damage to both vessels was estimated at approximately 25,000 dollars. V2's operator was issued a citation for no anchor light on.
