Working from an established design, the Seattle-based naval architect firm Jensen Maritime Consultants Limited have
drawn a very tidy 3400 HP docking tug. Building at Eastern Shipbuilders in Panama City Florida the boat
will be delivered to her owners, Thames Towboat Company Inc.
of New London Connecticut, this fall.
The boat, to be named John A. Wronowski, will have a 34-foot beam on a length-over-all of 96 feet and a molded depth of 14 feet 9 inches. Main engines will be a pair of V-16-cylinder Cummins KTA50-M2 rated for 1700 HP each at 1800 RPM. The engines will turn into Schottel 1010 Z-drives fitted with ducted 2100 mm (82.67-inch) propellers. Electrical requirements will be met by a pair of Cummins-powered 95 kW generator sets. A Cummins N14M fire pump engine will supply the boat’s two 2,000 gpm fire fighting monitors.
Deck equipment includes a JonRie Inter Tech hawser winch
Extensive hull fendering includes below waterline fenders as the boat will be used for docking naval craft including submarines at Groton, Connecticut.
Accommodation includes six berths. Tankage will be provided for 30,000 gallons of fuel, 6,150 gallons of water and 550 gallons of lube oil. The boat has a design speed of 12 knots.
