MV Iyanough

MV Iyanough is a high-speed ferry that operates for the Steamship Authority on a route between Hyannis and Nantucket, Massachusetts.

Iyanough was built by Gladding-Hearn Shipbuilding to an Incat Crowther design at a cost of $9.7 million and was delivered to the Authority in January 2007. She was christened and commissioned into service during a ceremony on Nantucket Island on March 24, 2007. Iyanough measures 154 ft in length, with a beam of 39 ft, and draws 5.3 ft. She is powered by four MTU diesel engines, which give her a top speed of 38 kn when fully loaded. She has a passenger capacity of 393, with 350 indoor seats and 40 on the outer deck.

On the night of June 16, 2017, Iyanough crashed into a jetty in Hyannis harbor, injuring fifteen passengers.
