RedactedNarrative: On the above date and time A hit and run vessel accident occurred and was witnessed by a good Samaritan. The subject witnessed a pontoon boat that had black panels and black top strike marker number 8 in the Hibiscus Bay Channel. The witness advised the vessel left the area at a high rate of speed and returned to a local marina. Upon my arrival at the marina I canvassed the area and was unable to locate the vessel. The witness was unable to provide a registration number for the vessel. The marker was broken off at the water line. USCG was notified and responded to the scene and provided a notice to Mariners. The suspect vessel was never located.
