The Staten Island Boat Graveyard, located off Arthur Kill Road and Rossville Avenue, is the final resting spot for dozens of rusting and abandoned boats of all sizes. Since the 1930s, the site has been used as a dumping ground for a variety of ships. The Boat Graveyard was once home to as many as 400 vessels; today, the number has been estimated to be between 25-40 decaying ships. The 'Witte Marine Equipment Company', known today as the 'Donjon Marine Company', controlled the salvage yard for decades. The company founder, John J. Witte, staunchly refused access to the boat graveyard to the curious public and only allowed paying customers to salvage boat materials. In 1980, when John J. Witte passed away, the ownership passed down to his son, who took more of an active role in salvaging of the materials. The ships in the graveyard have a rich history. Included in the wreckage is the fireboat 'Abram S. Hewitt', one of the boats which aided the rescue of victims in the General Slocum disaster in 1904. Two U.S. submarines, one of which dates back to World War II, and cargo boats are also present in the ship graveyard. Today, the ship graveyard is restricted from the public and photographers. The crumbling and dilapidated ships are a hazard to the public, but there is still a way to see them at close range. To enter the marshy trail that leads to the view, you must pass an equally tantalizing sight of the old Rossville Cemetery. This abandoned graveyard dates back to the 1750s.
