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 Transport maintained two fleets. Their Northeast Fleet or "Green Fleet" that operated in Philadelphia, Pennsylvania. And a Southern Fleet or "White fleet" that operated out of Tampa, Florida.

However, in the years that followed many changes came to Interstate Oil. A company called Southern National Resources (also known for a time as SONAT Marine) purchased Interstate Oil Transport and SONAT eventually sold out to Maritrans Operating Partners LLP.

In 1998, Maritrans's northeast fleet was thinned, and the Charger 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.
