The 85-ft. tug, Sea Bull built by Blount-Barker Shipbuilding was delivered to its port of Bayonne
, NJ, on April 21, 2002. The vessel will be used for marine towing in the greater New York area. The Sea Bull is powered by a pair of 12-cylinder, 3512B diesel engines, which produce 1,100 hp at 1,200 rpm. The Caterpillar engines run through Twin Disc 4.03:1 reduction/reversing gears which turn Aquamet shafts and two Kahlenburg, stainless, 4-blade 76-in. propellers. The vessel can maintain a free running speed of 12 knots. The Sea Bull has a Timberland Almon Johnson electric towing winch and a pair of Caterpillar 65 kW diesel generators to supply service power for the winch and other on-board uses. The tug is rated for forward bollard pull of 25 tons.
The construction of this vessel was based on the classic Blount design
of the tugs Pathfinder and Usher built in 1969 and modified by Bristol Harbor Marine Design. The vessel was designed and engineered using CAD/CNC computerized cutting technology. Construction on the Sea Bull began in November 2001 with delivery in 6 months time. Sea Wolf Marine was founded by Mr. Wittich in 1987. The contract towing firm is based in Edison, NJ and operates in the New York area. The new Sea Bull is now the sixth tugboat in their fleet.
