Custom Aluminum Ferry Designed and Built for Long Island Coast Waters

 
Gulfstream Shipbuilding won a contract through the United States Department of Homeland Security for a passenger/vehicle ferry to service the New York and Connecticut waters. This 118 x 27 x 10.75 ft. crew boat-style vessel will be capable of transporting passengers, freight and vehicles in and around the waters of the Eastern Long Island Sound and Gardiner’s Bay. The vessel has an expected delivery date of April 2017.
 
“Gulfstream Shipbuilding is not only familiar with the Eastern Long Island Sound waters; our team has delivered three ferry vessels to North Ferry Company that operate near these waters,” stated James Murray, Sales Manager of Gulfstream Shipbuilding. “We are proud of our 35 plus year history of building strong aluminum crew boats for all types of conditions.”
 
Working with Naval Architect C. Fly Marine Services, Gulfstream Shipbuilding and its design team have incorporated key design elements to meet and exceed the Critical Vessel Objective. The welded aluminum, mono hull, diesel propelled, quad screw passenger / vehicle ferry includes a 6’ x 6” draft and 75 Hp Wesmar Hydraulic Dual Prop Thruster. Caterpillar diesel engines have been identified to meet the 26 knot performance requirement. 
 
The hull structure is robust and designed for strength with considerations for ice, but not overly heavy as to affect performance, maneuverability, seaworthiness, comfort and speed requirements. Paying particular attention to the beam at waterline and dead rise considerations, the hull design provides for minimal frictional and wave-making resistance along with the center of gravity to meet the peak performance envelope and to ensure adequate speed and efficiency. 
 
Gulfstream's hull design is similar to that of a Gulf Coast Crew Boat, with a diminished cargo deck overall and a narrower beam at the waterline to reduce overall resistance at semi-displacement speeds. A sharp entry and moderate dead rise will provide a comfortable ride platform within the operational envelope.
