RedactedNarrative: V1 and V2 were competing in a Hobie Cat Regatta on Lewis and Clark Lake on June 19, 2017.  At approximately 1430 hours there was a collision between V1 and V2 that resulted in O1 being removed from V1 and suffering a broken left leg.  WCO was called about the accident and was informed that O1 was at the hospital emergency room in Yankton, SD.  WCO went to the hospital and started gathering information.  O1 was not able to speak to WCO as he was in surgery at the time.  WCO was able to get the personal information of O1 and P1 while at the hospital.  
   
  WCO went to the lake and obtained the information from O2 and P2 at Lewis and Clark Lake.  WCO also inspected the boats involved and gathered the registration information from V1 and V2.   WCO talked to O2 about what happened.  O2 stated that he was rounding a buoy and just as he was passing the buoy he had a collision with V1.  O2 stated that he never saw V1.  He stated that O1 ended up in the water and he was unsure of how that happened.  O2 and P2 immediately stopped sailing and rendered aid to O1.  
   
  WCO met with race officials to determine what rules they follow for the race and if they would make a determination of who violated any rules.  WCO was told that this will be determined sometime Wednesday (June 21) evening.  WCO checked in with race officials on Thursday (June 22) and no decision had been made at that time.  
   
  On Friday (June 23) WCO met up with race officials and they stated that V2 was the give way vessel and V1 was the stand-on vessel.  They further stated that both racers were disqualified from that race because their rules also state that each vessel shall take action to avoid a collision and V1 did not take that action.  
   
  WCO then met with O1.  O1 did not speak English so WCO spoke through a translator.  O1 stated that he had the wind over starboard and was going to round the buoy.  During the collision with V2 the trapeze rigging of O1 became entangled in the hulls of V2 and O1 was pulled overboard.   O1 stated that he was under water until his trapeze rigging snapped and he was able to rise to the surface.  O1 believes that his leg was struck by the hull of V2 and that is what caused the brake.
