Built in 1973, by Main Iron Works of Houma, Louisiana as the Charger for Interstate Oil Transportation of Philadelphia, Pennsylvania.

At the time Interstate Oil Transportation operated two fleets. Their Northeast Fleet or "Green Fleet" operated in Philadelphia, Pennsylvania. And their Southern Fleet or "White fleet" which operated out of Tampa, Florida.

However, over the years many changes came to Interstate Oil, when a company called Southern National Resources (also known as SONAT Marine) acquired Interstate Oil Transportation.

Eventually a group of managers at SONAT Marine offered to form a partnership to raise the funds necessary to purchase the SONAT Marine subsidiary. These eleven partners included some who had worked for IOT since the 1950's. On April 14, 1987 Maritrans Partners of Tampa, Florida. Assumed control of SONAT's tug and barge operations.

However, in March of 1989 the Exxon Valdez ran aground in Prince William Sound. In 1990, the Oil Pollution Act of 1990 was passed calling for the double hulling of all petroleum carrying vessels by 2015. As well, as other stipulations that effected Maritrans including manning, preparedness and spill prevention. Maritrans filed suit to fight the stipulations set fourth by OPA '90.

Maritrans had begun to consolidate its business by the mid 1990's. By first, backing out of the black oil trade and carry only petroleum products and petrochemicals. The phosphate trade and local transport in Baltimore that was part of the Harbor Towing subsidiary did not fit into Maritrans's new business model. As Maritrans backed out local companies moved in that included Bouchard Transportation of Melville, New York and Vane Brothers of Baltimore, Maryland.

In 1998, the tug was acquired by Dann Ocean Towing of Tampa, Florida. Where she was renamed the Captain Dann.

She is a model bow, twin screw ABS Maltese Cross A-1 Towing Service; Maltese Cross AMS certified tug. Powered by two Caterpillar D-399 TA main engines with Lufkin RLS 4218 reduction gears turning two 104(in) diameter by 86(in) fixed pitch four bladed propellers for a rated 2,250 horsepower.

Her electrical service is provided by two 60 KW generators driven two 6-71 Detroit Diesel engines. The tug's capacities are 37,000 gallons of fuel oil, 315 gallons of hydraulic oil, 822 gallons of lube oil, 365 gallons of gear oil, 10,000 gallons of water.

Her towing gear consists of an INTERcon SD175 towing winch outfitted with 2,000(ft) of 1.75(in) towing wire, as well as a New England Trawler Capstan featuring a 5,000 lb line pull.
