RedactedNarrative: On July 13th, 2014, at Lake Powell in Slick Rock Canyon our ski boat (V1) was damaged while moored to the back of our houseboat. 
  
  The driver of the boat  (V2) that caused the damage came within 30 feet of the back our boat and within 15-20 feet of our daughters and her friends who were swimming at the time.  Operator2's speed boat caused a very large double wake. 
  
  On the first circular pass, there was a young man standing on the raised portion of V2. When the boat passed by our daughter and her friends, the young man appeared to intentionally throw himself off the back of the boat.
  
  The driver (V2) then circled 360 degrees at a high rate of speed in order to pick up the ejected party. This occurred directly behind our moored boat causing not only one but two consecutive 2-3 foot wakes. Our moored power boat lurched 3' onto the back of the houseboat causing the driver's side window to impact the houseboat slide. 
  
  The window was completely shattered. 
  
  This incident not only caused damage to our boat but we were thankful the driver did not hit the swimmers in the water. Our daughters screamed and my oldest was shaking with fear because she was afraid. In her words:  "I thought he was going to run us over." 
  After the incident the driver came over and apologized. A female passenger in his boat commented, "Did OUR boat cause this damage?"
