RedactedNarrative: I talked to the people in the boat.  They stated that the waves came up, and a wave came into the boat.  The operator slowed the boat down.  This caused the bow to lower, and another wave came into the boat.  They tried to bail the water out until the engine quit.  The boat filled with water, and turned over.
  
  Operator was brought in with a pwc, and he stated that the boat he was on is sinking.  He stated that the boat is 10 - 15 minutes northwest of the park.  I told him that I could not go to that area because our boat was on another boat that reported to sinking (that boat made it in without our help, and there was another call).  I told him that we will get to his boat as fast as we could, and I called 1J509 about the incident.  He called out search and rescue.  By the time Utah County Search and Rescue showed up, other boaters had brought in all 9 people on the boat.  I called Provo EMS for one victim.  She seemed that she was going into shock.  Provo EMS checked her out, and stated that she was having panic attack. While I was waiting for our boat to finish with their last call.  I had subject call their insurance agent to see what their agent wanted for us to do.  His agent stated that we could tow it into ULSP Marina.  I took 2 SAR members, and we went to retrieve the boat.  I towed the boat at 2.5 mph into ULSP marina without incident.  They called for the tow truck.  AMPM towing showed up.  They caused a lot of damage when they turned it over.   There is video on youtube  showing the tow truck operator flipping the boat over.  On youtube name is "How to ruin a boat in 30 seconds", and the second on is 2011 07 17 21 14 59 45.
