RedactedNarrative: This report documents a two vessel collision in which Vessel 1 was the give way vessel and Vessel 2 was the stand on vessel.  Vessel 1 was drifting while not under power 1/4 mile south west of the Rend Lake Resort Cove no wake area.  Vessel 1 was facing west. Vessel 2 exited the no wake area of Rend Lake Resort Cove and just came onto plane heading southbound.  Vessel 2 struck Vessel 1 in the bow at a 90 degree angle.  Visibility was limited due to darkness and Vessel 1 failed to have a stern light activated.  The time of the accident was 8:52PM, 44 minutes after sunset.  The sky was clear.
  
  Vessel 1 was not under power (drifting) without proper lighting (no stern light).  Vessel 1 was occupied by 2 persons both seated in the passenger''s seat.  Vessel 1 was facing west at 270 degrees.
  
  Vessel 2 had just exited a no wake area and was travelling parallel to a partnering vessel.  Vessel 2 was heading southbound at 180 degrees.  Vessel 2 had just came onto plane at 24-26 mph.  
  
  Vessel 1 was struck by Vessel 2 in the bow.  Both occupants of Vessel 1 had retreated to the stern of the boat, were standing, and verbally signalling for Vessel 2 at the time of the collision.  Both occupants of Vessel 1 were ejected into the water.  Vessel 2 travelled over the bow of Vessel 1 causing severe damage from the lower units passing through the bow of Vessel 1.
  
  Vessel 1 did not have it''s stern lights activated as required at the time of the accident.  It was 44 minutes after sunset.
  
  Vessel 2 was the stand on vessel and displayed careless operation by operating at a speed greater than allowing him to reduce speed and avoid the collision with Vessel 1.  The operator of Vessel 2 described his procedure for getting his vessel on plane which indicated operator inattention.  The environmental condition of darkness also was a contributing factor causing Vessel 2 to not see Vessel 1 until immediately before the collision.
  
  One female occupant of Vessel 1 was treated by emergency medical personnel at the boat launch and refused transport to a medical facility.
