RedactedNarrative: The operator went back to the marina where he rented the vessel and while waiting for an estimate the marina called in the accident to their vessel. The operator stated he hit an "unidentified object". The Marine Patrol Officer when on the same course the operator did, discovered that he was on the wrong side of a navigational marker which brought the vessel closer to submerged rocks close to the surface. The vessel hit the submerged rocks but did not disable it.
