RedactedNarrative: Vessel 2 and Vessel 3 were tied together, adrift in the main channel of the Illinois River approximately 1/2 mile downstream of 12 Mile Island.  Five (5) fenders were placed between the vessels.  A floating raft was secured behind vessel 2 and occupied by three (3) passengers. Vessel 1 was cruising downstream. 
  
  Vessel 2 operator stated that upon seeing Vessel 1 approaching, he motioned for the operator of Vessel 1 to slow down as to avoid throwing a large wake towards Vessel 2 and Vessel 3.  Operator and occupants of Vessel 2 and Vessel 3 stated the speed of Vessel 1 remained consistent.  After passing their location at an estimated distance of 50'', a large wake caused Vessel 2 and Vessel 3 to collide, resulting in a cracked hull on Vessel 2. 
  
  Vessel 1 operator stated he observed the two boats in the main channel while cruising downstream at an estimated speed of 18 MPH.  Vessel 1 operator and occupants stated he slowed to an estimated speed of 5-6 MPH, passing Vessel 2 and Vessel 3 at an estimated distance of 100''. 
  
  I examined the damage to Vessel 2 and estimated the damage to likely be in excess of $2000.  Vessel 1 operator was cited for careless operation of a watercraft. He was released on a Notice to Appear.  A court date is scheduled for August 9, 2016 at the Jersey County Courthouse.
