On July 24, 2010, at approximately 7:30 pm, Vessel #1 and occupants were traveling in a northward direction on Canyon Lake near the area of campsites 14 and 15 of Canyon Park, headed back to boat ramp No. 18 where they were camping.  They were traveling approximately 150 feet from shore when a sudden loud crack was heard as the vessel was traversing across waves in the water.  Immediately after the sound, the vessel started taking on water and the passengers put on life jackets, exited the vessel, and swam to shore.  A passerby in another boat, who was not identified, assisted in towing this vessel to boat ramp No. 18 where it flipped over once they arrived at the boat ramp.  For the rest of the evening operator attempted to load this vessel onto his trailer without success.  At approximately 10:15 pm, State Game Warden arrived on scene and interviewed the operator and occupants, and obtained written statements from them.  I was not able to conduct a water safety inspection of this vessel as it was upside down when I arrived and all contents of the vessel were strewn about.  At approximately 11:00 pm, New Braunfels Towing was contacted and the vessel was winched onto a flat bottom trailer, upside down, and transported off site at approximately 11:45 pm.  Alcohol was verified not to be a contributing factor to this incident.  
  
Investigator from TPWD completed the report.
