RedactedNarrative: On sunday 6/28/15 i was advised by laporte county sheriffs dept. Of a boat accident that had taken place on lake michigan in the area of the washington park beach in michigan city.  The additional information provided to me was that there were no injuries and the involved parties were standing by at the beach.
   
   upon my arrival i found two personal watercraft with three males standing near them speaking with u.s. coast guard personnel.  As i spoke with the parties involved i discovered the two operators involved in the accident were father and son.  At the time of the accident the father (operator2) was operating the personal watercraft that he owned.  His son (operator1) was operating a personal watercraft owned by a family friend. They explained to me that they are neighbors.
   
   i examined both personal watercrafts and found that the blue yamaha (v1)  had extensive damage to the hull of the vessel with most being in the midship area of the starboard side.  The damage to the vessel was of a crushing nature to the fiberglass.  The yellow seadoo personal watercraft (v2) had only scuff marks to the bow of the vessel and mostly on the rub rail.  When asked both operators and owners advised that neither vessel appeared to be taking on water after the accident and were operational.
   
  I found no witnesses to the accident other than the two operators.  So after speaking with both separately to their accounts of the accident the details leading up to and the accident are as follows.  Vessel 1 operated by operator1 was traveling west parallel with the shoreline and in his words pretty fast, with v2 operated by operator2 just behind and keeping pace to the north or starboard side of v1.  V1 then sated that turned to the right or north and began to stop and v2 stated that when he realized v1 had turned in front of him and was stopping he to began to slow down rapidly and turned to the left in an attempt to avoid the collision.  V2 then collided with v1 in a 't' bone fashion and the operator of v2 was thrown from the watercraft into the water.  V1 operator remained on the watercraft throughout the collision. This account of the accident is consistent with both of the operator's individual accounts as well as the damage to both vessels.
   
   by the accounts of the operators when v2 slowed down it limited his steerage by the sheer nature of the jet propelled watercraft whether or not by not slowing down would have avoided the accident is unknown.
   
  It should be noted at the time of the accident both operators were wearing u.s. coast guard approved floatation devices.  I found no odor of alcohol and did not observe any characteristics by either operator of either drug or alcohol involvement.
