RedactedNarrative: On July 23, 2011 at approximately 6:34PM Vessel 1 was operating in a northwest direction at approximately half throttle in a dense fog towards Vessel 2 which was anchored approximately 1/4 mile south of the entrance of North Point Marina, approximately 100 yards east of shore.  The 2 occupants of Vessel 2 attempted to signal the operator of Vessel 1 from approximately 100 feet by waving their hands, shouting, and sounding a horn.  The operator of Vessel 1 did not see Vessel 2 due to the heavy fog and struck Vessel 2 on the port side at amidships.  Vessel 1 traveled over Vessel 2, shattering the windshied, removing the hand rail, and causing damage to the port side hull, seats, and engine cover with the bow eye,lower unit, and propeller.  Vessel 1 reentered the water at the starboard stern corner of Vessel 2 and came to rest approximately 100 feet northwest of Vessel 2.  The operator of Vessel 1 returned to Vessel 2 to render aid.  
  
  I arrived at the scene by boat at approximately 6:45PM and escorted both vessels back to the launch ramps at North Point Marina.  Both vessels were operational after the accident.  The operator of Vessel 2 was taken to Vista East Hospital in Waukegan for treatment for lacerations to the bottoms of his feet caused by stepping on broken glass from the windshield of his vessel.  He was treated and released.  No other significant injuries were sustained from the accident.  The operator of Vessel 1 was cited for Careless Operation of Watercraft.
