ISLAND HOME She serves the 7 mile route between Woods Hole and Martha’s Vineyard since March 5, 2007. Constructed by VT Halter Marine Inc, of Moss Point, MS, to a design by the Elliott Bay Design Group of Seattle, WA. She has a 255’ length with a beam of 64’. She is powered by two EMD Diesel engines delivering a total of 6000 HP with a top speed of 16 knots. For her route, she has the fastest crossing time of approximately 30 – 35 minutes. The freight deck can accommodate 60 vehicles with an additional 16 on hydraulic lift decks, for a total capacity of 76 vehicles. The freight deck can be configured to hold motor coaches, trucks or semi-trailers. She is capable of carrying a total of 1,200 passengers.

MARTHA’S VINEYARD The SSA took delivery of the M/V M.V. from Atlantic Marine, Jacksonville, Florida in 1993. She is assigned to Woods Hole - Martha’s Vineyard service and is classed as a conventional, diesel, twin-screw, passenger/vehicle ferry. A quick look reveals a basic similarity in hull dimensions, speed and capacities to the 1974 vintage M/V NANTUCKET. Her 230’ length, 60’ beam, 3000 HP EMD powerplant, 14-knot speed, and vehicle deck load generally mirror the older vessel. There the similarity ends, however, as more modern amenities and necessities such as improved ADA access, interior and exterior seating upgrades, interior passenger space size, and enhanced maneuvering characteristics make the M/V M.V. a more passenger friendly vessel. click here to view handicap accessibility       back to top

EAGLE (Original EAGLE was a steam “side-wheeler” and one of the first ferry vessels to serve the Islands) EAGLE has served as the Nantucket runs “workhorse” since 1987. She was designed by Boston naval architect, John Gilbert and built by McDermott Shipyard in Louisiana. The over-standard height freight deck and additional pilothouse level are immediately apparent and may look somewhat awkward; but, underwater, her bulbous bow, small sponsons, and “bustle” aft provide a surprisingly comfortable ride in the Nantucket Sound seaway. Passengers can relax in the EAGLE’S NEST, the upper deck satellite TV lounge. click here to view handicap accessibility       back to top

NANTUCKET NANTUCKET was designed by Jack Roper and built in Jacksonville, Florida, arriving in Woods Hole as “state-of-the-art” in 1974. The SSA was still transitioning from the era of steam to the modern age of diesel power, and NANTUCKET incorporated many new features that are still viable today. She underwent an engine change to EMD power in 1988; ADA access has been improved; and minor changes made; but she is, essentially, the original vessel. Her 230’ length, 60’ beam, 14-knot speed, and easy handling have proved to be the right combination for service to both Islands where she has served with distinction. NANTUCKET normally serves her namesake island on the summer schedule and Martha’s Vineyard in winter when the vessels on the “short run” are in for annual maintenance. click here to view handicap accessibility       back to top

GOVERNOR (Retained U.S. Coast Guard name from Governor’s Island service) The GOVERNOR’s life began in 1954 running from San Diego to Coronado. When a bridge was built spanning her original route, GOVERNOR shifted venue to Seattle-based Washington State Ferries. As new vessels arrived, GOVERNOR again became surplus and was sold to the U.S. Coast Guard for the New York Harbor Governor’s Island service. For a third time in her career, GOVERNOR became surplus with the closing of Governor’s Island. She subsequently joined the SSA fleet in 1998 as a back-up vessel on the Vineyard route. The “double-ended” GOVERNOR is the longest and widest vessel in the SSA fleet at 242’x 65’ and the only vessel with diesel-electric power. Three Caterpillar diesels power two electric propulsion motors giving her a 12-knot speed. She has limited passenger accommodations, but sports a large freight deck capable of quickly clearing the standby line on busy days. click here to view handicap accessibility       back to top

KATAMA (South coastal beach area of Martha’s Vineyard) The KATAMA of today is a 235’x 40’, 13.5-knot, “freight” vessel. In 1981, she started life as an Offshore Supply Vessel running to oil rigs and platforms in the Gulf of Mexico. 1988 marked her first conversion to ferry service when the SSA added a rounded stern to fit loading ramps and a small passenger area. Ten years later a fifty-foot midsection was added along with an engine upgrade to more powerful EMDs. KATAMA is certified for 149 persons on board and serves (on most schedules) Martha’s Vineyard as a truck and back-up car carrier. She also performs important tasks such as moving all of the Island’s SEMASS recycling plant trash across the Sound; bringing hazardous propane and petroleum products to heat Island homes and power Island vehicles; and moving every sort of general cargo to power the Island life and economy. click here to view handicap accessibility       back to top

GAY HEAD (Brightly colored clay cliffs of northwest Martha’s Vineyard) A KATAMA sister-vessel running to the Gulf of Mexico offshore oil fields, GAY HEAD was brought to the SSA a year after KATAMA arrived. Both vessels were designed by Guarino & Cox of New Orleans, but built in different yards for different owners. GAY HEAD performs the same freight vessel service as her sister, running most of the year to the island of Nantucket. She also received a fifty-foot midsection and an engine upgrade in the late 1990s. Although GAY HEAD is certified for the same passenger load as KATAMA, her inside accommodations are larger and her engine room conversion layout has been improved. Like KATAMA she is 235’x 40’ and 13.5-knots. click here to view handicap accessibility       back to top

SANKATY (The east headland of Nantucket) SANKATY was the third former offshore supply vessel to join the SSA's current fleet as a “freight” vessel. This 1981 Rysco Shipyard vessel came to the SSA in 1994. Although SANKATY started life as a slightly larger vessel than KATAMA or GAY HEAD, she has not undergone the lengthening conversion of the other two SSA “freight” vessels (197’x 40’). Her initial conversion design by Boldcraft was more extensive in the realm of passenger amenities, and she is certified for 300 persons. SANKATY serves the SSA as a “relief and standby” vessel. She has a more limited vehicle carrying capacity than the other “freight” vessels and spends the majority of her service performing off-season overhaul relief. click here to view handicap accessibility       back to top
