A large, derelict pleasure craft that sank in Great Bay off Radio Road in Little Egg Harbor Township has been marked with a buoy to keep it from being a navigational hazard, said a representative from Coast Guard Station Atlantic City.

The boat became stranded off Mystic Beach on Oct. 5 and was secured to a tree by the Coast Guard. Subsequently, it was untied during the night by a person or persons unknown and drifted into Graveling Point meadows.
