Hyline Cruises Takes Delivery of Fourth High-Speed Ferry From Gladding-Hearn

SOMERSET, Mass. – September 14, 2016 – Hyline Cruises has accepted delivery of Grey Lady IV, a new 493-passenger, high-speed catamaran designed by Incat Crowther and built by Gladding-Hearn Shipbuilding, Duclos Corporation. The ferry will provide year-round passenger service between Hyannis, Mass. and Nantucket Island.

The fourth Incat built by the shipyard for the Cape Cod ferry operator is the largest in the fleet, with additional passenger capacity, increased luggage space and a VIP lounge. According to Hyline officials, the ferry’s VIP cabin offers a superb forward-facing view and is the only such cabin on a fast ferry serving the route.

Measuring 153.5 x 34.5 feet and a draft of approximately eight feet loaded, the vessel is powered by four Cummins QSK60-M EPA Tier 3 diesel engines, each delivering 2,200 Bhp at 1,800 rpm. Each hull is equipped with a 125 KW Cummins EPA Tier 3 generator.  With a rating of 1641 kW each, the engines were selected to be run at modest speeds during day-to-day trips, with reduced wear and tear and increased time between overhauls. The rating allows the vessel to maintain its service schedule on just three engines. “This kind of margin and redundancy is just prudent business for a ferry that will operate close to 5,000 hours per year, said Peter Duclos, the shipyard’s president.

Each engine is propelled by a Hamilton HM721 water jet through a Twin Disc MG61500SC horizontally-offset gearbox. The ferry’s top speed is more than 34 knots with a fully-loaded deadweight of 64 metric tons.
