RedactedNarrative: At approximately 1430 HRS on 7/2/11, after letting his friends off at the Lakeview boat ramp in the Perry State Park, the operator of vessel 1 backed said vessel from the dock to wait for his friends to get the trailer.  At said time, vessel 2 (trailered) was attempting to launch from said boat ramp.  Additionally, an unknown vessel, located between the dock and vessel 2, was being launched or loaded on or from a trailer.  
  
  While backing away from the dock and making a sharp turn to starboard, the operator of vessel 1 increased the throttle.  Due to either the fact that excess throttle was provided or that the throttle became "stuck", vessel 1 then collided with vessel 2.  The initial impact occurred as the bow of vessel 1 collided with vessel 2''s outboard engine and stern.  
  
  During the collision, the impact from vessel 1 reportedly caused injuries to two female occupants located in the aft section of vessel 2.  Injured occupant 1 received treatment on 7/2/11 and was diagnosed with headache, neck pain, strain of neck muscle and neck strain.  Injured occupant 2 reportedly suffered head and neck trauma.  Specifically, she advised that her head impacted with a swimming ladder and the aft deck of vessel 2.  At an unknown time on 7/2/11, she went to the hospital for treatment but after having waited for five hours, she left prior to receiving any.  Three days later, she reportedly received massage treatment to relieve muscle stiffness in her neck, back and shoulders due to "whip-lash".    
  
  After the collision, the bow of vessel 1 rested on the stern of vessel 2, wedged between injured occupants 1 and 2.  After the operator of vessel 1 shut off the engine, some of the occupants of vessel 2 then helped push vessel 1 off of vessel 2.  
  
  After reporting the incident, the owner of vessel 2 transported injured occupants 1 and 2 to Stormant Vail ER in Topeka, KS for evaluations.
  
  Structural damage was sustained to the outboard motor and aft section of vessel 2 and to the hull of vessel 1.
