 The first American double-ended ferries appeared the following year with the paddle-wheelers "Jersey" and "York" of Robert Fulton's York & Jersey Steamboat Ferry Company.Excellent for transporting vehicles, the double-enders were well adapted to New York Harbor, where there was considerable demand for speed and efficiency (vehicles could drive on and off from either end, and time-consuming turns were not necessary).It has been estimated that over 400 double-ended ferries operated in New York Harbor during the nineteenth and twentieth centuries.
