RedactedNarrative: The operator took his vessel to a local marina to have an estimate for the damage on his vessel. He was told by the marina staff that he needed to report the accident. Three days later the marina called to report the accident with Marine Patrol. The operator stated he hit an object that was floating in the water. The center and port pontoon sustained severe indentations in the shape of a large round object. The operator stated he did not know what he had hit. The Marine Patrol Officer canvassed the area finding nothing that would make that kind of damage.
