RedactedNarrative: On Satruday, June 4, 2022, at around 1500 hours, I received a call of a pontoon boat stuck on the rocks at Sheffield. I responded and when I arrived Operator was stuck on a rock wall. Operator had rented the boat from Florence Harbor Marina. The boat was not moving and was stuck on a rock. I had Operator trim up the engine and the boat starting moving in the current. All of the blades were off of the propeller. The vessel was towed back to the Marina. Operator stated that she was trying to go the Sheffield boat ramp and did not know she could not cross over the rock row that is outside of the channel. The vessel was rented the next day and the outboard broke off at the transom. It is believed that the damage done by Operator the previous day caused the outboard to break off the following day. Nothing further to report.
