RedactedNarrative: On 12/05/2015 at approximately 1000 hrs. FWC dispatch advised of a vessel accident with no injuries in the vicinity of Convoy Point. I immediately contacted the reporting party who was National Park Service (NPS) Dispatch. NPS advised that a boat collided with a marker at Angel fish Creek and navigated back to Convoy Point. I documented the accident and concluded that the vessel collided with a submerged pilling. This pilling wasn’t visible from the surface and there was no posted warning signs that the operator could have seen in order to avoid collision.
  	
  NPS Ofc. advised me that he called US Coast Guard Sector Miami to report the navigation Hazard and they got him in contact with BMC In charge of Aids to Navigation Team. I made contact with BMC, he advised he was in route to the collision site to identify the navigational hazard. Later on that day, he called me back advising that they had found the piling that caused the navigational hazard. He explained that they had use a contractor company by the name of Industrial Divers Corporation. They replaced damage markers on Angel Fish Creek. It seems that they removed an old steel piling, but due to poor visibility they didn’t notice a wooden marker submerged under water. BMC provided me with a copy of the invoice for this work that is also attach to this report.
  
  I later documented that Vessel 1 was identified as a 25ft Sea Fox bearing FL3679PN. The vessel had damage cracks on the port side of the transom, damage on the port side engine cowling, port side lower unit was completely removed during impact, port side hydraulic steering also removed during impact and gauges stock on impact speed. After gathering witness statements and taking photographs, I provided a case number and my contact information. 
  
  
  Based on the video evidence, BMC statements and damaged found on the vessel, I conclude that the port side lower unit of the boat impacted a submerged pilling. This pilling wasn’t visible from the surface and there was no posted warning signs that operator could have seen in order to avoid collision.
