RedactedNarrative: On August 4, 2019 vessel one (V1) was operated by operator one (01) on the Missouri River below the Fort Randall Dam with one passenger (V1P1) on board. Neither 01 nor V1P1 were wearing their PFD's.
  
  Operator two (02) was operating vessel two (V2) on the Missouri River below the Fort Randall Dam. 02 was not wearing a PFD.
  
  At approximately 8:15 PM, V1 was heading east, away from the Randall Creek Recreation Area boat Ramp; V1P1 was sitting on the bow of the boat. V2 was "spot-locked" (staying stationary with trolling motor) approximately 15 yards south of the eagle observation point, facing east.
  
  01 observed two unidentified boats approximately 30 yards south of the eagle observation point (south of V2's location). 01 slowed down to approximately 8 miles per hour and turned to port as he approached the unidentified boats in order to avoid creating a wake.
  
  01 's vision was obstructed by V1P1 and did not realize he was approaching V2's stern. V1P1 advised 02 they were about to hit V2.
  01  responded by putting his boat in neutral and turning sharply to starboard. 01 's turn to starboard caused V1·  s front (bow) port side to collide with V2's boat motor. 01 's turn to starboard also caused the front of V1's keel to collide with V2's rear (stern) starboard gunwale.
