Construction

Morro Bay was the sixth 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 Morro Bay was constructed in 1980 by Tacoma Boatbuilding of Tacoma, WA, as an icebreaking tugboat for the U.S. Coast Guard. Mobile Bay was commissioned on March 28, 1981, at the U.S. Coast Guard Reserve Training Center in Yorktown, VA. She remained stationed there until 1998 when she was decommissioned. In 2001, she was recommissioned and stationed at New London, CT.

The Morro Bay was restationed at Cleveland, OH, in early 2014, to strengthen the Coast Guard’s Great Lakes icebreaking fleet.

In 2014, Morro 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 in mid-2015.

USCGC Morro 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.
