About Us

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, groups, and trucks. Martha’s Vineyard ferries depart from Woods Hole and Nantucket ferries depart from Hyannis. Our seasonal high-speed passenger 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. Our U.S. Coast Guard-certified crews are committed to the highest level of safety at sea. We are also dedicated to making your trip both comfortable and convenient with spacious seating, snack bars with beverages including beer, wine and mixed drinks, and free Wi-Fi and TV on-board. For a perfect day trip, or a longer getaway, Martha's Vineyard and Nantucket make wonderful destinations—with magnificent beaches, charming scenery, and fabulous shopping and dining. Visitors can take advantage of convenient public transportation to our mainland docks, and bus service as well as taxis, car rentals and bike rentals on the Islands.
