Design
editThe 140-foot (43 m) Bay-class tugboats are operated primarily for domestic ice breaking duties. They are named after American Bays and are stationed mainly in the northeast United States and the Great Lakes.
WTGBs use a low pressure air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull, reducing horsepower requirements. They can break up to 30 inches of ice continuously.
Construction and career
editThunder Bay was built by the Bay City Marine Inc., in Tacoma, Washington in 1985. She was launched on 31 July 1985 and later commissioned in 1986.
Thunder Bay is homeported in Rockland, Maine. During icebreaking season, Thunder Bay frequently breaks the Penobscot River for ice clearing and flood prevention, but may also surge to the Hudson River in New York to assist when necessary.
On 4 February 2021, Thunder Bay conducted a icebreaking mission at the Penobscot River.[2] On 18 June, the ship finished the In-Service Vessel Sustainment program and departed Coast Guard Yard in Curtis Bay, Maryland.[3]
