RedactedNarrative: Operator1 stated that he was driving his vessel, towing a tube, and had just started going, increasing speed and his bow was just coming down as he came onto plane when he heard a bang as he hit something.  He stated he never saw anything before he heard the impact noise and that he immediately stopped and shut his motor off.  One occupant on v1 who had been sitting in the center bow seat of the Sea Ray facing the rear of the boat and had not seen what had happened, was ejected from the vessel into the water.  
  
  At that time he stated he saw a PWC in the water behind them with 2 people in the water.  I asked Operator1 who all had been in the boat or on the tube at the time off the accident.  He stated that his father and himself were the 2 adults on the boat with two children and that one adult female and 3 children had been on the tube.  Two people from V2 were injured.  
  The adult female was complaining of great pain to her upper right leg and her head.  She also had visible injuries to her right arm.  The male child had a large laceration/contusion to his right hip.  
  
  While they filled out statements I began to look for possible damages or other indications of the impact on the Sea Ray vessel (Vessel 1).  I observed large black scuff marks/transfers and scratches on the starboard side of Vessel 1.  These scuff marks and scratches started very near the front of the vessel on the starboard bow running through the vessels bow numbers and continuing toward the stern of the vessel as they progressed lower on the starboard side from just below the rub rail down to the water line.  The marks ran down approximately 1/2 the length of Vessel 1.  There was no other visible damage to Vessel 1 when it was in the water but I did note that the bilge was running the entire time I was present.
