RedactedNarrative: The person operating at the time of the incident was told me that he had met victim and the two females at the boat ramp around 1:00pm but he was unsure of the actual time he had arrived.  Victim is his friend and the owner of the vessel. Victim had been operating the vessel until right before the incident. I asked how many people were on board and he said four;the two females in the vessel were friends with victim. Operator said he had just met them that day. I asked operator if they were drinking and he said he wasn't sure, he thought so. I asked operator if he had been drinking and he said no. I did not detect any odor of an alcoholic beverage from his person. He did not appear to be impaired in any way. I asked operator where the incident occurred. He explained that the incident happened in between two bridges which i identified as the wilson blvd and the lejeune blvd bridges. 
  
  Operator stated that he had just taken over as the operator of the vessel so victim could go check on something. Victim proceeded to the bow of the vessel to check on something. I asked operator what victim would be checking for in the bow of the boat. Operator said that earlier in the day the vessel's engine was over heating or something, he wasn't sure but it had not been running correctly. I then asked operator if they were having problems with the engine which is in the back of the vessel, why was victim looking over the bow of the vessel which is in the front of the boat? He said he wasn't sure. Operator then said that victim was sitting in the bow of the vessel they had been on plane for about 30 to 40 seconds and then they hit something in the water and the vessel jerked. Then victim was thrown backwards off of the bow. He went underneath the vessel and when he turned the vessel around, he saw victim holding his arm up out of the water and it was badly injured. He went back and they helped him into the vessel and they made a tourniquet from victim's shirt to help control the bleeding. Operator stated that "everything happened so quickly, he wasn't exactly sure what happened." 
  
  A doctor came in and told us that victim was asking for his friend and wanted him to come see him. I was done asking him questions, so we went into the er room where victim was. They spoke to each other briefly, and then i introduced myself to victim, explained to him that i was there to investigate the incident and asked him if he felt like answering a few questions and explain to me what happened. He said that was fine. He said "i was sitting in the bow of the boat and we were running along. I asked him if the vessel was on plane and he said "yes". Victim stated that he thought they struck something in the water that caused the vessel to jerk suddenly but he wasn't sure what it was. I asked him if the engine was running properly, he said that the trim was messed up and they had just had the vessel worked on at tideline marina in jacksonville that morning. 
  
  They went straight from tideline marina to the boat ramp. Victim made the comment that maybe something had gone wrong with the engine since it had been worked on that morning, causing the vessel to suddenly jerk while they were moving along. I asked him if the vessel stopped when it hit the obstruction in the water and he said "no it did not stop," i asked victim to explain to me how he was sitting in the vessel. He said that his left side was facing the driver. He had a hard time explaining his exact position. He stumbled around with the explanation that he had to sit in the bow of the vessel because of the design of the vessel "you have to distribute the weight evenly." he asked me if i had seen the vessel and i replied that i had not. There were other officers at the boat ramp looking at his vessel. 
  
  I repeated the statement back to victim to make sure i had it correctly. I said victim "you were sitting in the bow of the vessel in a seat, not on the side right?". He replied "yes" and operator you were
