Sunken Key West boat leaks diesel, triggers Coast Guard response
Diesel leaked from a 48-foot boat at Perry Marina as Coast Guard crews boomed the spill to keep fuel out of Key West waters.
A 48-foot boat sank at Perry Marina in Key West with about 700 gallons of diesel aboard, and Coast Guard investigators reported active fuel discharge from the vessel’s bow and stern as crews moved fast to contain it. The sinking turned a marina salvage job into an urgent water-quality response in one of the Keys’ busiest harbors, where fuel can spread quickly through slips, channels and nearby seagrass waters.
Responders deployed containment boom around the vessel to limit the diesel and keep it from drifting farther through the marina. The Coast Guard said federal funds would be used to lift the boat and remove the remaining fuel and oil, a step meant to stop the spill from continuing while the wreck sat in the water. The immediate concern was not just the vessel itself, but the fuel load it carried and the chance that diesel could move beyond Perry Marina into surrounding waters used by boaters, tenants and nearby businesses.
The stakes are high in Key West because Perry Marina sits within the broader protection zone of the Florida Keys National Marine Sanctuary, which NOAA says shelters nearly 6,000 marine species. The sanctuary also contains the only coral barrier reef in the continental United States and the largest documented contiguous seagrass community in the Northern Hemisphere. NOAA says sanctuary regulations are enforced by state and federal law enforcement agencies, underscoring how quickly a marina incident can become a resource-protection case.
The National Response Center serves as the sole federal point of contact for oil and chemical spill reports and is staffed around the clock by the Coast Guard, a setup designed for exactly this kind of emergency. NOAA has long described vessel groundings and similar incidents as major threats to sanctuary habitat, including the Big Cat Express case in the Key West area, which ended in a $2.2 million settlement for restoration. In the Keys, even one sunken boat can trigger wider consequences for water quality, marine life and access to working waterfronts.
The latest sinking also comes against the backdrop of a broader derelict-vessel problem across Monroe County. In 2025, local cleanup efforts removed 237 vessels since August 2024 and cut active derelict cases from more than 300 to 44, a reminder that salvage work and environmental protection are now tightly linked throughout the Keys.
