The person who posted the video on YouTube says: "A rare clip of a now defunct amusement park that had been around since the 1890s in some form. The ship would take customers to both Marshall Hall and Mount Vernon. They had a contentious relationship with Mount Vernon (across the Potomac) who felt an amusement park should not be so close to the birthplace of George Washington. It was ultimately given the death blow by President Ford, who authorized the purchase of the property by the Park Service. It was dismantled and out of business by 1980. "
