C-Tractor is a class of fourteen tractor tugs built by North American Shipbuilding Company between 1989 and 1993 for Alpha Marine Services, a subsidiary of Edison Chouest Offshore.[1] The lead ship of the class was William M , also known as C-Tractor 1[2][3]

C-Tractors measure 189 GT.[2] They are propelled by Z-drive pods, powered by twin EMD 16-645 engines rated at 4,000 shaft horsepower (3,000 kW). The tugs mount fore and aft fire-fighting monitors, capable of pumping a total of 3,500 US gallons per minute (790 m3/h).

In 2005, C-Tractor 1 was sold to Bay-Houston Towing Company and based in Corpus Christi, Texas. Her sister ships continue to be owned by Alpha Marine; six - C-Tractor 2, C-Tractor 3, C-Tractor 4, C-Tractor 5, C-Tractor 12, C-Tractor 13 - were at one point chartered to the United States Navy.[4][5]
