USCGC Thunder Bay (WTGB-108) is the eighth vessel of the Bay-class tugboat built in 1985 and operated by the United States Coast Guard. [1] The ship was named after a bay in the U.S. state of Michigan on Lake Huron. She is homeported in Rockland, Maine
The 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.
Thunder 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]

In commission from 1944 until 2003 she saw service in Pacific, Caribbean and Atlantic waters as well as the Great Lakes. In 1947 Bramble was present at the Nuclear testing at Bikini Atoll and in 1957 a circumnavigation of North America involved a forced traverse of the Northwest Passage. After decommissioning in 2003 Bramble became a museum ship in Port Huron, Michigan. In 2018 she was sold to a private owner, who is preparing MV Bramble to repeat her historic 1957 circumnavigation of North America.
The USCGC Morgenthau (WHEC-722), was the eighth of twelve 378-foot dual-powered turbine/diesel Hamilton-class high endurance cutters (WHECs) built by Avondale Shipyards in New Orleans, Louisiana.

USCGC Sturgeon Bay is the newest of the United States Coast Guard 140-foot (43 m) Bay-class cutters. Homeported in Bayonne, New Jersey, the primary missions of Sturgeon Bay and her crew are Domestic Icebreaking and Ports, Waters, & Coastal Security. During the winter months, Sturgeon Bay is responsible for providing search and rescue capabilities to the ice-covered areas in New York City and the Hudson Valley, as well as throughout coastal New England. The cutter also facilitates the safe navigation of commercial product, including gasoline and heating oil, through the ice-choked Hudson River from New York City to Albany. All Bay-class cutters, including Sturgeon Bay, 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.
USCGC Katmai Bay (WTGB-101) is a United States Coast Guard Cutter, and the lead ship of the Bay-class of icebreaking tugboats. At 140 ft (43 m), she is designed to have greater multi-mission capabilities than the 110' Calumet-class Harbor Tug (WYTM).

USCGC Penobscot Bay is the seventh of nine United States Coast Guard 140-foot Bay-class icebreaking tugs. Homeported in Bayonne, New Jersey, the primary missions of Penobscot Bay and her crew are Domestic Icebreaking and Ports, Waterways, & Coastal Security. During the winter months, Penobscot Bay is responsible for providing search and rescue capabilities to the ice-covered areas in New York City and the Hudson Valley, as well as throughout coastal New England. The cutter also facilitates the safe navigation of commercial product, including gasoline and heating oil, through the ice-choked Hudson River from New York City to Albany. All Bay-class cutters, including Penobscot Bay, 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.
