Built in 2006, by Thoma-Sea Boat Builders of Houma, Louisiana (hull #126) as the Chesapeake for Vane Brothers of Baltimore, Maryland. However, construction was initially begun for Odyssea Vessels of Berwick, Louisiana. When the deal unraveled with Odyssea Vessels, Vane Brothers of Baltimore, Maryland purchased the unfinished tug from Thoma-Sea Shipbuilders. Along with the Kathy C., that would become the Patapsco. And, the hulls that would become the tugs Nanticoke, and the Wicomico. Upon her completion, she was the fourth Patapsco class tug built for Vane Brothers. Designed by Frank Basile of Entech and Associates of Houma, Louisiana. Although, she is slightly larger variation on Patapsco class tugs.
