Built in 1968, by Main Iron Works of Houma, Lousiana (hull #196) as the Scott Chotin Jr. for the Chotin Transportation Company of New Orleans, Louisiana.
In 1982, the tug was acquired by the Reinauer Transportation Companies of Staten Island, New York. Where she was renamed as the Dace Reinauer.
In 2008, the tug was outfitted with a JAK-400 coupler system. The project required a large amount of the steel in her bow to be replaced. As well as the basic design of her bow was altered to accommodate the load boxes for coupler system, that would affix the tug to notch of the barge.
The existing wheelhouses were removed, and the tug was fitted with a single aluminum wheelhouse, with a 43(ft) height of eye. The towing winch was removed, the tug's raised bow, and 02 deck was extended aft 10(ft) to add counter weight for increased stability. As well as, to create additional space below decks to accommodate a third service generator, and additional air compressor dedicated to her JAK coupler system. The work was performed at Feeney's Enterprise of Kingston, New York. The engineering of the refit was performed by JMS Naval Architects.
The Dace Reinauer was the Reinauer Transportation Company's fourth conversion of a conventional tug, to an Articulated Tug and Barge (ATB). And the seventh ATB added to the Reinauer Transportation Company's fleet.
Powered by two, sixteen cylinder, Caterpillar 3512 diesel engines. Turning two, cast steel, fixed pitch propellers, mounted in kort nozzles. The tug was equipped with flanking rudders, for a rated 3,400 horsepower.
In 2015, the tug was repowered with two, MTU/DDC 16v4000 diesel engines. Her stern was enclosed to add reserve buoyancy, her flanking rudders were removed, and the tug was fitted with new stacks.
Her electrical service is provided by two, 75kW generator sets. With a third, 75kW auxiliary generator set. The tug's capacities are 51,320 gallons of fuel, 1,515 gallons of lube oil, 475 gallons of hydraulic oil, and 9,049 gallons of water.
