RedactedNarrative: On 2-23-14 at approximately 1915 hours, Vessel-1 was traveling east into Gordon Pass at 20 MPH. The vessel struck the head pin and caused significant damage to the bow of the vessel. The operator and one passenger suffered serious injuries, while the other passenger suffered only minor scratches on his hand and leg. The passenger with minor injury was able to get the vessel back to the dock and then transport the two injured people to the hospital for treatment. 
  
  On 2-23-14 at approximately 1915 hours, operator and two occupants were on Operator's 36 foot Contender (DO 1153390) heading east towards Gordon Pass. He activated the vessel's auto pilot system and set it for the head pin at the entrance to Gordon Pass. When they were approximately two miles west of Gordon Pass, Operator came off plane and put the vessel in neutral to check his position in reference to the channel markers, due to the sun going down and visibility almost gone. When Operator felt that he knew where the markers were, he put the vessel in gear and increased speed. As the vessel was getting up on plane there was a sudden impact and both Operator and Injured2 were knocked unconscious. Injured3 took control of the vessel and idled into the pass and to the dock where the vessel is kept. Injured3 then transported Operator and Injured2 to Naples Hospital where they were both admitted for treatment. 
  
  During this investigation, I obtained the blood results from the Naples Community Hospital records building using the consent form Operator signed. According to the records, Operator was not impaired at the time he was treated. The GPS tracks downloaded from Operator's GPS showed his vessel heading towards Gordon pass from offshore. It should be noted that tracks made while the vessel is on auto pilot are straight lines and tracks made by vessels being manually steered look very different, those tracks are not straight at all. Operator's tracks are very straight heading toward the pass at approximately 30 MPH, then the speed slows and the vessel stops. When the vessel track picks up speed and heads toward the pass it is again a very straight line. Therefore it appears that Operator did not turn off the auto pilot and as a result his vessel struck the head pin. Operator advised he did not think he had to report the accident to authorities because he did not strike another vessel and he was more concerned about his injured friend; 
   
  Injured3 suffered minor scratches on his hand and leg as result of the collision. No medical treatment was required.; Operator's head/face struck the center console when the vessel struck the head pin. Operator suffered a broken nose and received several stitches in the middle of his forehead at the eyebrow line as a result. Operator was admitted to NCH in downtown Naples, treated then released the next day.; Injured2 was standing to the right of the operator when the vessel struck the head pin. As a result of the impact, Injured2' head struck the T top support causing moderate to severe injury to his head. Injured2 was admitted to NCH in down town Naples for two days. No brain injury was sustained, however he did receive 30 staples to close the wound.
