RedactedNarrative: The operator left the Town Docks and headed in a southerly direction towards Mile Island. He stated he was going about 5mph when he struck rocks. The vessel was drivable so the operator drove it back to where he rented it. He was asked to point out on a map where the rocks were and pointed to a black top buoy area. The operator stated there should be a sign there and was informed by the Marine Patrol Officer that is why we have buoy's.
