Grey Ghost

Grey Ghost is a 105-foot (32 m) ex-Navy steel tug lying approximately 21 miles offshore of Panama City Beach, Florida, and is the first intact vessel intentionally sunk as an artificial reef in those waters. On 12 July 1978 the vessel was acquired through federal surplus property by the Panama City Marine Institute, cleaned, prepped and towed by volunteers, then deliberately scuttled on her portside near hard bottom in 105 feet (32 m) of water as the opening act of an ongoing artificial reef programme.

The wreck rests on her portside close to a natural reef edge that has since been augmented with fiberglass boat hulls and scrap steel, creating an extensive fish habitat around the 105-foot-long, 20-foot-wide steel hull. As an extended offshore dive, reaching Grey Ghost takes roughly 6–8 hours of travel time.

The site has become a productive breeding ground and attracts a wide assortment of aquatic life typical of local Gulf waters. The depth of 105 feet (32 m) places it firmly in the advanced category, and divers should note that although most of the vessel's doors have been removed, wreck penetration remains a hazard and should not be attempted without proper equipment and prior training.
