Gladding-Hearn Delivers Ferry
Gladding-Hearn Shipbuilding, Duclos Corporation, has delivered Iyanough, a new 393-passenger, high-speed ferry, to the Woods Hole, Martha's Vineyard and Nantucket Steamship Authority in Massachusetts. The all-aluminum catamaran, designed by Incat-Crowther in Sidney, Australia, is 154 ft. long and 39-ft. abeam. It draws only 5.3-ft. The vessel, which will operate a 26-mile route from Hyannis, Mass., to Nantucket, features Incat's S-Bow hull shape to provide additional reserve buoyancy during very large seas. The Steamship Authority's second fast ferry is powered by four MTU 12V4000M70 diesel engines, each delivering 2335 Bhp at 2000 rpm and propelled by a Hamilton HM-721 waterjet through a ZF-4650D reverse-reduction gearbox. Equipped with a VT/MDI active interceptor motion control system, the vessel's top speed, in moderate sea conditions, is 38 knots when fully loaded with a deadweight of 51 metric tons at 100% MCR. According to Duclos, the vessel's fuel consumption is about 445 gallons per hour. Designed for zero discharge, the vessel includes five heads. With interior sound levels of 72 dba, the main and upper cabins feature Beurteaux seating, heating and airconditioning, along with energy-efficient, double-glazed windows. Additionally, there is a digital audio/visual public address system with nine displays throughout the vessel and a snack bar in the main cabin. A separate luggage room carries more than 14,000 pounds of luggage and 24 bicycles. SciTec Inc. at its Ocean Engineering Centre in Vancouver B.C. The tests resulted in slight modifications to the bow rake of the barge. To achieve the desired 10-knot speed for the combination tug-barge with the required shallow 6.5-ft. draft for river operations, three of Cummins' new Tier II complaint QSK19 engines were selected. Each of the three engines will deliver 660 hp continuous duty to one of the three 63 x 54-in. props in Rice Speed Nozzles with triple rudders. For travel in open waters the 1980-hp tug, with a molded depth of 11.3 feet, will be capable of ballasting down to 8.9-ft. The tug is currently under construction at the Chiasson Welding facility in Larose, La., while the barge is being built at a yard in Houma. Delivery is anticipated in the spring of 2007. The owners' representative to the project is James Huffman Sr.
