Hy-Line Cruises, a division of Hyannis Harbor Tours, Inc., Hyannis, Mass., has taken delivery of Grey Lady IV, a new 493-passenger, high-speed catamaran from Gladding-Hearn Shipbuilding, the Duclos Corporation. The fourth Incat-Crowther fast ferry built by the Mass.-based shipyard for the Cape Cod passenger ferry company is larger and more stylish in design than previous vessels. The new ferry will provide year-round passenger service between Hyannis and Nantucket Island.
The new, all-aluminum ferry measures 153.5 feet (46.8 m) long, 34.5 feet (10.5 m) at the beam, and draws approximately 8 feet (2.5 m), loaded. The vessel is powered by four Cummins QSK60-M, EPA Tier 3 diesel engines, each delivering 2200 Bhp at 1800 rpm. Each engine is propelled by a Hamilton HM721 water jet through a Twin Disc MG61500SC horizontally-offset gearbox. The ferry’s top speed is over 34 knots when fully loaded at a dead-weight of more than 64 metric tons, including 6.4 metric tons of luggage, said Peter Duclos, president of the shipyard. In the event of a failure of one of the propulsion systems, the boat will still keep the schedule, but will require full power from the remaining 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 Duclos. Each hull is equipped with a 125 kW Cummins QSB7-D (M), EPS Tier 3 generator.
Similar to Hy-Line’s current high-speed catamarans, the new ferry is outfitted with a Naiad Dynamics trim-tab, ride-control system to improve passenger comfort and safety. The system’s motion sensor measures the relative movement of the vessel and transmits an electrical signal to the appropriate hydraulic device to counter the boat’s action through the waves, Duclos explained. “By keeping the unwanted motion and steering to a minimum, the system can also minimize the speed loss in rough seas.”
The main cabin seats 160 passengers and includes a full service concession, heating and air conditioning, two heads, and a large luggage room aft. An etched-glass screen separates the passenger seating area from the concession and condiment counters. The second deck, with interior seating for 154 passengers, features heating and air conditioning, premium seating forward, three heads, interior and exterior cocktail bars, and exterior seating for 46 passengers. The premium seating area for 32 is separated from the main passenger area by a half-height bulkhead with glass screens. The third deck, with the pilothouse forward, provides exterior seating for 137 passengers.
Access to the wheelhouse, which is equipped with centerline and port and starboard engine and waterjet controls, is from exterior doors in the aft bulkhead.
