The Bay-class tugboat is a class of 140-foot (43 m) 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 20 inches (51 cm) thick, and break ice up to 3 feet (0.91 m) thick, through ramming. These vessels are equipped with a system to lubricate their progress through the ice, by bubbling air through the hull.
Service Life Extension Program[edit]
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 (including removal of lead paint). The first WTGB SLEP is scheduled for 12 months; however, once the Yard achieves a satisfactory production labor learning curve (anticipated after Hull #3), the Yard will complete two 140-foot WTGB SLEPs per year, with an anticipated duration of 9 months each. The first of nine cutters (Morro Bay) entered production at the Coast Guard Yard on July 1, 2014.[1] Morro Bay returned to her homeport of Cleveland in September 2015 [2]
