The Staten Island Ferry carries 22 million people annually and is a significant part of NYC's transportation system, offering a free ride and stunning skyline views. The NYC Department of Transportation maintains its ten-vessel fleet and terminals.
Three of the ferries that were built to make the trip across the harbor were bought by the U.S. Navy to fight in the civil war. The Southfield I, Westfield I, and the Clifton I. None of these ferries ever returned to New York.
