Interstate Navigation purchased the vessel after she was dry-docked at a shipyard in Savannah, GA. During the winter of 2012/2013, Interstate engaged in a complete refurbishment of the vessel’s hull and superstructure, and a complete rebuild of the propulsion and vital systems. The ISLANDER was delivered to New England in June 2013, and began passenger ferry service to Block Island.

The ANNA C. was originally designed to operate as the “winter boat”, and ran year round on the Block Island run, until the ferry BLOCK ISLAND went into service in 1997. The ANNA C. was originally considered to be an improved design, from that of her near sister ship CAROL JEAN, which had served as the previous winter vessel.

The vessel was designed by John W. Gilbert Associates, Inc., and is USCG, Subchapter “K” certified for 1124 passengers. The CAROL JEAN was originally designed to provide seasonal (spring/summer/fall) service to Block Island from Pt. Judith. She also became known as “the Island Boat” as the vessel originated and ended her daily schedule at Old Harbor, where she lays overnight through the present day. In 1984 and 1985 as the island’s transportation needs increased, the operating season of the CAROL JEAN increased to include portions of the winter months.

The improved spaces and enhanced maneuvering characteristics make the CAROL JEAN a more passenger comfort oriented vessel.

 

M.V. MANITOU

M.V. MANITOUInterstate Navigation Company owner John H. Wronowski began construction of the passenger/vehicle ferry MANITOU in 1969 at Thames Shipyard and Repair Company in New London, CT. The vessel was launched in 1969, and construction was completed in 1970. The vessel was designed by naval architect Robert S. Simons. At the time of her delivery, she was billed as the largest USCG, Subchapter “T” certified vessel ever to be built, and represented the “new generation” of marine transportation of passengers, vehicles and freight to Block Island from the mainland. The vessel began service in the spring of 1970 on the Pt. Judith to Block Island run, operating from the end of the State Pier in Galilee. The MANITOU replaced the ferry SPRIGG CAROL as the year round vessel. The vessel originally side loaded vehicles and passengers in Pt. Judith and Block Island. In 1971, the vessel was fitted with a stern loading ramp (a part of the original design) and further improved the Company’s ability to efficiently transport trucks and automobiles to Block Island. In 1971 the company also installed the land based stern loading ramps first on Block Island, followed by Pt. Judith. The ferry MANITOU ran full time, every day as the year round vessel until 1985, when she was relieved part time by the CAROL JEAN. She was later replaced as the year round vessel in 1986 by the ferry ANNA C. She became a seasonal vessel (April through October) carrying passengers, autos, trucks and freight opposite the CAROL JEAN. When the ferry BLOCK ISLAND went into service in June of 1997, the MANITOU became the standby/reserve vessel, until she returned to service on the Newport to Block Island run for the summers of 2000 through 2003 and 2008. The MANITOU has served since 2004 as the standby/reserve vessel, with several brief returns to the Newport run in relief of the ferry NELSECO. The vessel is USCG, Subchapter “K” certified for 302 passengers, 100 feet in length, 97 gross tons, and the vessel’s (2) Cummins diesel propulsion engines (1000 HP) deliver a service speed of 12.5 knots.
