Neah Bay was the fifth ship of the Bay Class USCG Icebreaking tugboats. The Bay class vessels were designed to replace the Coast Guard’s aging class of 110′ harbor tugs. The Bay Class tugs feature a strengthened icebreaking hull, and is capable of breaking 20 inches at continuous speed and 6-9 feet while backing and ramming. The Bay Class tugs are also equipped with a unique “bubbler” hull air lubrication system. The bubbler pushes air through ports on the cutters hull, allowing for an upward flow of air and water along the hull, reducing friction and increasing efficiency.

There were 9 Bay Class tugboats constructed for U.S. Coast Guard service, and 6 of them are stationed on the Great Lakes. Those are the Katmai Bay, Bristol Bay, Mobile Bay, Biscayne Bay, Neah Bay, and Morro Bay.

Her Story

USCGC Neah Bay was constructed in 1979 by Tacoma Boatbuilding of Tacoma, WA, as an icebreaking tugboat for the U.S. Coast Guard. Neah Bay was laid down on August 6, 1979, and launched in Tacoma on February 16, 1980. She was delivered to the Coast Guard on August 18, 1980, and then sailed to the Great Lakes to take up her new station. USCGC Neah Bay was commissioned on October 25, 1980, at Cleveland, OH, replacing the USCGC Kaw at that station.

In 2016, Neah Bay went to the U.S. Coast Guard’s shipyard in Baltimore, MD, where she underwent her Service Life Extension Program (SLEP) refit. She returned to the Great Lakes at the end of the year.

USCGC Neah Bay remains an important asset to the Coast Guard’s Great Lakes icebreaking fleet, and assists in keeping marine traffic moving during the winter months.
