RedactedNarrative: On June 11, 2016 at approximately 1450 hours, we responded to a boat accident that occurred earlier in the day at Grayrocks Reservoir outside Wheatland, WY.  We initially went to Wheatland to talk with the owner of one of the boats.  
  
  Operator1 stated that he had three other individuals on board with him that morning.  These individuals were two of his sons and a friend of his son.  Operator1 stated that they were a  ways from shore still and were starting to head into the far West dock of Gate 1 at Grayrocks.  
  
  Operator1 stated he was starting to turn towards the dock at approximately 1--15 miles per hour when the other boat came up quick on their port side and tried to turn to avoid the accident and they collided, with the sides of their boats coming together.  
  
  Operator1 stated he checked his throttle at this time to see if he had changed anything and if that was the reason they hit, but said his throttle was unchanged.  Both parties came back in contact to be sure no one was injured.  Operator1 stated that the other operator had told him that he had seen Operator1 heading towards the dock, then looked away back at shore to see where he was going to swing around, and when he looked back in front of him realized the two boats were going to collide and took evasive maneuvers to attempt to avoid the accident.  
  
  We then went to his storage unit to look at the damage to his boat, which was a 1999 Bayliner Capri.  There was a large scrape that went across most of the port side of the boat, including green paint transfer near the back end.  There was also a large crack in the fiberglass that wa approximately 25 inches in length (see attached pictures).  
  
  Afterwards, we went to Grayrocks Reservoir to contact the owner of the second boat.  Operator2 stated that he had two other individuals on board with him that morning.  Operator2 stated that he was heading straight west and was looking towards the cove and "not watching a boat coming on starboard side".  
  
  He turned back and Operator1's boat was there, so he turned to get out of the way and his boat "glanced off the other boat".  Operator2 stated that he was insured through Farmer's Foremost and had already made a claim.  We had Operator2 pull his boat, a 1998 Lund, out of the water to look at the damage.  Operator2 could not tell us exactly where the damage was and the only thing we could see that seemed like it could be from the accident was scratches and scrapes to the rivets on the back end of the starboard side (see attached pictures). 
  
   In our opinion, it seems like the accident was a result of inattentiveness of both operators; however, it seems that Operator2 may have looked away for a period of time that was unreasonable for the situation.  We believe that Operator1 was headed into the dock and may have turned in front of Operator2.  Operator2 was focused on shore and did not see Operator1 turn towards the dock until they were too close.  Operator2 turned to avoid Operator1, causing the boats to collide parallel with Operator2' back end coming around and hitting the port side of Operator1's boat.
