USCGC BISCAYNE BAY (WTGB-104) History
Built in Tacoma, WA by Tacoma Boatbuilding, the CGC BISCAYNE BAY was commissioned on December 8, 1979. She has been homeported in St. Igance, MI since her commissioning. The BISCAYNE BAY is the fourth vessel of the Coast Guard's 140 ft "Bay" class. This class of icebreaking harbor tug was designed to replace an aging fleet of 110 ft harbor tugs and to meet the Coast Guard's domestic icebreaking responsibilities well into the next century.
