USCGC Neah Bay (WTGB-105) is the fifth vessel of the built in 1980 and operated by the United States Coast Guard. The ship was named after a bay located within the state of Washington and bordered by Puget Sound.
The 140-foot 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.
Neah Bay was laid down by the Tacoma Boatbuilding Co., in Tacoma, Washington on 6 August 1979. She was launched on 16 February 1980 and later commissioned in Cleveland, on 25 October 1980.
A Himalayan cat named Casca in which was rescued by Lt. Commander Molly Waters during a stint in Alaska, now sits on board the ship.
