RedactedNarrative: This accident occurred on or about April 28, 2016 at approximately 1630 hours. This deputy was notified of the accident on May 2, 2016. As I was not on scene immediately after the accident, I can only report both statements of the operator and rental boat owner. I did speak to both parties and also investigated the boat which was damaged. The rental company, who witnessed the accident, stated that the operator was attempting to dock the vessel at their rental facility when she came in at the wrong angle and had to correct the vessel. 
  
  In doing so she had to back away from the dock and when she put the vessel in forward, she over throttled the boat slightly while making a turn to return towards the dock and struck a piling. The boat hit the piling on the rear starboard side according to the rental company which caused the transom on that side to crack allowing water to fill the vessel. 
  
  The operator indicated the above was correct however, she stated that she hit closer to midpoint on the vessel and not to the rear. She also indicated that once she left the vessel, no one came to her indicating she had damaged it so she left.
  
  The owner stated they did not notice the damage until the boat started sinking approximately 30 minutes after the rental was returned. They further stated the vessel was immediately put on a lift and has not been rented since then. I investigated the vessel and took pictures (attached). In my opinion, I did not see any indication of a midpoint strike as indicated by the operator. There was fresh damage to the starboard rear transom area that backed up the eye witness statement given by the rental company's owner. The gel coat had what appeared to be a new scratch through it in this area and stress cracks which I could not verify were new or from previous incidents. The operator was not cited at this time due to circumstances, however, she would be at fault for careless operation.
