RedactedNarrative: On May 27th 2017 operator was operating his 20 ft vessel westbound in the Indian River Inlet. Operator, was making approx. 8 knots (plowing) when his vessel came into contact with IR buoy #11 which is a green can. The vessel contacted the buoy with the port bow. Upon contacting Operator, I could see the damage to the chine on the port side of the bow on his vessel. Operator explained to me that only he and one other person were onboard at the time of the accident and that there were no injuries. Operator explained to me that there was no other visible damage to the boat at that time and the boat was not taking on water. Operator advised me that he could not see the buoy because the current was pulling it under the surface. On May 28th 2017 Operator advised me that his GPS was no longer working and thought it to be a result of the accident.
