Description
USCGC Morro Bay (WTGB-106) is the sixth vessel of the Bay-class tugboats built in 1980 and operated by the United States Coast Guard. The ship was named after a seaside city in San Luis Obispo County, California.
The 140-foot (43 m) Bay-class tugboats 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 ice-breaking capabilities by reducing resistance against the hull, reducing horsepower requirements.
Each patch measures 4″ (102mm) in diameter.
