The USCG Utility Boat, or UTB, was a standard utility boat used by the United States Coast Guard for a variety of inshore missions. The 41 ft (12 m) UTB was designed to operate under moderate weather and sea conditions where its speed and maneuverability made it an ideal platform.

The boats were welded 5086 aluminum, with a molded fiberglass superstructure and twin Cummins diesel engines with conventional shafts and propellers. They were capable of light towing, and were originally fitted with demountable fire monitors. Typical boat crew was 3.

They were constructed at the Coast Guard Yard in Baltimore, Maryland, from 1972 to 1979.

As of 2005 there were 172 operational boats. Beginning in 2008, these aging boats were retired and replaced with the Response Boat-Medium over a 6–10 year period. The last boat, 41410, was decommissioned in Grand Haven, Michigan on 31 July 2014.[2] The 45-foot Response Boat – Medium is the class's replacement.
