Originally named the Machigonne, the Mackenzie-Childs Yankee Ferry was built in 1907 in Philadelphia, Pennsylvania; its job was to ferry people, cargo and livestock to and from Portland, Maine and Casco Bay Islands. The Navy acquired the vessel in 1917 during World War I to transport men and supplies to training stations. They would commission the Ferry again in World War II. Between its work in both World Wars, it was used to ferry immigrants from Ellis Islands during the Immigration Boom. It was retired commercially in 1983, leading artist couple Mackenzie-Childs to acquire the ferry and convert the vessel into an unconventional and quirky houseboat. It now docked in New York City.
