Steamship Authority

The Steamship Authority is the largest ferry service to the Islands of Martha's Vineyard and Nantucket from Cape Cod. We offer the lowest fares and the most frequent daily departures for passengers, automobiles and trucks. Martha's Vineyard ferries depart from Woods Hole and Nantucket ferries depart from Hyannis. Our seasonal high-speed passenger-only ferry, the M/V Iyanough, gets you to Nantucket, dock-to-dock, in just an hour. Since 1960, we have been the lifeline to the Islands year-round.
