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. They 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 (SLEP)

A SLEP is a major overhaul intended to extend a vessel's service life; it is typically scheduled as the vessel approaches the end of its originally planned service life. The Bay-class tugboat SLEP project includes significant system upgrades and improvements to the propulsion plant; to the 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).
