RedactedNarrative: Both vessels were participating in a fishing contest on the lake. The contest utilized a "shotgun start" where all vessels leave at once for their particular fishing location. 
  
  Watercraft #1 started with several other boats and the high angle of his bow while accelerating prevented him from seeing Watercraft #2 which was stationary. Operator #1 also states that boats on either side of him were also accelerating and causing large wakes, which further distracted him from keeping forward lookout. 
  
  Bow section of WC #1 collided with stern of #2. Impact caused passenger/victim in WC #2 to fall onto a boat cooler causing a back injury. Both boats returned to shore. No use of alcohol/controlled substance noted by officers on scene. Victim was transported by personal vehicle to hospital for treatment. Life jackets were worn by occupants of WC #1 but not by occupants of WC #2.
