RedactedNarrative: On September 10,2021 at approximately 1530 hours vessel FL311PT was traveling east through Snake Creek in Islamorada, Florida. The vessel struck a green stationary channel marker (7A) located on the South side of the channel. The vessel began to take on water and was beached. Commercial salvage arrived on scene and added pumps to remove the water from the vessel. Once I arrived, the vessel was being towed west through snake creek. I boarded the tow vessel gathered information on the occupants and conducted a safety inspection of the vessel involved in the incident. From statements made on scene and sworn written statements gathered, I concluded the operator was looking at the vessels GPS and struck the channel marker. Once the vessel was out of the water, I assessed the damage. The damage was to the port bow along the gunnel and first chine for almost the length of the vessel. The damage to the rub rail portion of the vessel had stress fracture damage consistent with a glancing blow on the channel marker. A 10-foot-long tear/rip was visible on the first chine of the vessel. The ripped section of the hull and was visible on the inside of the vessel. Black paint transfer from the struck channel marker was also present on the hull side of the vessel.
