RedactedNarrative: WCO received a report at approximately 9:30pm on the evening of August 26th, 2019 from a North Sioux City PD officer about a noninjury boat accident on McCook Lake. PD Officer had taken the initial report along with pictures. The vessels in the accident had already been trailered and back at their respective residence before the call was taken about the accident. According to the initial statement given to PD Officer, V1 and V2 were near each other on McCook Lake. V1O1 stated he started to slow down and turn, V2O2 also started to slow down and turn but struck V1 in about the middle of the port side with the rear of V2's port side. Pictures of V1 and V2 were taken by the PD Officer and included in the report for the WCO to follow up with. 
  
  WCO followed up with interviews and called in another WCO to help with measurements of the damaged vessels. WCO met with V1O1 and V1P1 for statements. These statements claimed V1 was traveling in a southwest direction on the lake and V2 was approximately 50 yards behind them and to the left. V1O1 started to turn left and noticed V2O2 coming toward him so he stopped to let V2O2 go in front of him. V2O2 then started going towards V1O1 and V1P1, V1O1 and P1 started waving their hands to get V2O2 to stop. V2O2 continued at same speed (25-30 mph), hit some uneven water and tried to turn away but he was to close and ran into V1O1 and V1P1. There was an impact between V1 and V2. V1O1 and V1P1 stated they got up from the floor after impact to ensure V2O2, that flew off the jet ski, was ok and look at the damage to V1. V1O1 stated V2O2 was ok and swimming back to V2. V1O1 and V1P1 observed the damage to V1, then drove back to the boat ramp to load up V1 and call Law Enforcement. 
  
  WCO also received a statement from V2O2. This statement included that V1O1 was doing circles and V2O2 was trying to jump those waves from V1O1. V1O1 was turning around, V2O2 saw V1O1 turning towards V2O2, V2O2 tried turning to miss V1O1 and let off the gas. Once the gas is let off, the steering stops. V2O2 caught the port side (impacted) of V1O1. V2O2 was unharmed but thrown from V2. 
  WCO's conducted measurements of V1 and V2.
  
  WCO talked again with V2O2 on September 19th. V2O2 admitted he was jumping the wakes created from V1O1 that was doing circles on the lake. V2O2 stated V1O1 would create the wakes for them to jump, then go further down the lake to do another circle to create more wakes. As V2O2 was jumping wakes he did not look up in time to witness V1O1 going into a left hand turn further down the lake. V2O2 stated he was going approximately 20-25 mph while jumping the wakes when he looked up and noticed V1 approximately 20-30 feet ahead of him. V2O2 stated he was jumping wakes not paying attention before he looked up to notice V1O1. V2O2 panicked and tried turning to avoid V1O1 but let off the throttle which enables him to steer. V2O2 then impacted the port side of V1 with his port side. V2O2 was thrown from V2 into the water. V2O2 was not injured. V2O2 was able to swim and retrieve V2 after the impact. It was stated V2O2 was wearing a engine cutoff lanyard. V2O2 ensured V1O1 and V1P1 was not injured and ok. V2O2 stated V1O1 was not close to other vessels when doing circles to create wakes. V1 and V2 then parted ways and trailered there vessels.
  
  WCO talked with V1O1 on September 23rd. V1O1 stated he was doing circles to create wakes for V2O2. V2O2 stated he drove in one circle and continued down the lake for 3-4 seconds or approximately 30-50 yards before he was going to start a left hand turn. At that time V1O1 looked behind him to see V2O2 approximately 70-75 yards behind him and 10 yards to his left.  V1O1 started his left hand turn, then observed that V2O2 was jumping the wakes from the first circle and driving towards V1O1. V1O1 put V1 in neutral. V1O1 believed that V2O2 was going to go past him around the front. V1O1 stated V2O2 kept going towards him in uneven water. During this time V1O1 and V1P1 started waiving there arms and yelling to get the attention of V2O2. V2O2 did not notice V1O1 until it was too late to turn. V1O1 stated  V202 tried turning away to avoid impact but it was too late. Before impact, V1O1 and V1P1 stated they tried getting to the middle of the boat. Impact was made at approximately the middle portion of the port side of the V1 by the port side of V2. V1O1 and V1P1 was knocked down but stood up and ensured V2O2 was ok and not injured after impact.  V2O2 was thrown from V2. V1O1 stated V2O2 swam a short distance to retrieve V2.  V1O1 stated V2O2 kept apologizing and stated "my bad". Both vessels parted ways.
  
  WCO believes from statements and interviews that V2O2 was jumping a wake of another vessel while unreasonable too close, operating at a unreasonable speed for the time, place and condition. V2O2 was cited for careless operation.
  
  WCO took measurements of the damage for examination and diagramming purposes. WCO Talbert concluded damage to the vessels indicates the vessels collided at an approximate angle of impact of 343 degrees to V1. The port side of the bow of V2 made contact with the port side of V1 and continued to make contact with V1 as it traveled toward the stern of V1. The damage to the port side and underside of the hull of V2 support it rolling or heeling as with a direction change to the starboard side of V2 exposing more of the underside hull. A direction change of striations at the port stern corner of V2 supports V2 changing direction as V2 was turning away from V1. The damage across most of V2 is approximately parallel to the centerline of V2 except for the damage near the stern. The damage to V1 supports it being in a bow elevated or higher pitch position that can occur as a vessel accelerates or decelerates. The damage to V1 begins about one third of the way back from the bow and ends about two thirds back from the bow toward the stern.
