Built in 1970, by Main Iron Works Incorporated of Houma, Louisiana (hull #239) as the Dad III for the Doucet and Adams Company Incorporated of Galliano, Louisiana.

In 1979, the tug was acquired by the Reinauer Transportation Company of Staten Island, New York. Where she was renamed as the JoAnne Reinauer III.

In 2008, she underwent an extensive refit at Feeney's Enterprises of Kingston, New York. This included the installation of a JAK 400 coupler system.

The tug's bow was modified to accommodate the coupler system. Her wheelhouses were removed, and replaced with a single, aluminum tower. Her main decks were enclosed to the 02 deck level. Her sides were extended outward in order to add weight for increased stability. Her towing winch was also removed. The engineering for the project was performed by JMS Naval Architects of Seattle, Washington.

In 2020, the tug was placed out of active service and was "laid up at Reinauer Transportation's yard at Port Richmond in Staten Island, New York.

In 2021, the tug was scrapped at Reinauer Transportation's yard at Port Richmond in Staten Island, New York.

Originally powered by two, eight cylinder, EMD diesel engines. In 2008, the tug was repowered with two, MTU diesel engines. Turning two, cast steel, fixed pitch propellers. She is a twin screw tug, rated at 3,600 horsepower.

Her electrical service is provided by two 50kW generator sets. With a third auxiliary generator set. The tug's capacities are 50,456 gallons of fuel, 7,396 gallons of fresh water, and 3,170 gallons of ballast water.
