Bay-class tugboat


The Bay-class tugboat is a class of icebreaking tugboats of the United States Coast Guard, with hull numbers WTGB-101 through to WTGB-109.
They can proceed through fresh water ice up to thick, and break ice up to thick, through ramming. It can also ram pressure ridges of up to eight feet in thickness. These vessels are equipped with a system to lubricate their progress through the ice, by bubbling air through the hull.

Service Life Extension Program

The WTGB SLEP project includes significant system upgrades and improvements to the propulsion plant; heating, ventilation, and air conditioning systems; installation of an engine-room fire-suppression system; boat launching davit replacement; Oily Water Separator replacement; stack exhaust configuration modifications; hull air-ice lubrication system; and crew habitability improvements to meet current standards. The first WTGB SLEP is scheduled for 12 months; however, once the Yard achieves a satisfactory production labor learning curve, the Yard will complete two 140-foot WTGB SLEPs per year, with an anticipated duration of 9 months each. The first of nine cutters entered production at the Coast Guard Yard on July 1, 2014. Morro Bay returned to her homeport of Cleveland in September 2015
