RedactedNarrative: Vessel 1 was traveling approx. 6 mph. Vessel 2 was traveling approx. 25 mph and passing an unknown vessel and when he completed his pass, he collided with vessel 1's port bow then side. 
  
  Vessel 2 had attempted to turn to the port at the last minute making contact on his starboard bow then side.  This sent the operator of vessel #1 into the passenger seat causing injury to his lower back.  I checked vessel 1 navigation lights and they were working properly.
