USCG utility boat
From Wikipedia, the free encyclopedia
The Utility Boat is one of the main boats used by the United States Coast Guard. The 41 ft (12 m) UTB is the general workhorse at multi-mission units. It is designed to operate under moderate weather and sea conditions where its speed and maneuverability make it an ideal platform for a variety of missions.
There are presently 172 operational boats. Currently these boats are being phased out, although a many will remain in operation for several years to come.
The boats are welded aluminum, with a molded fiberglass superstructure and twin Cummins diesel engines with conventional shafts and propellers. They are capable of light towing, and were originally fitted with demountable fire monitors, although most have been removed. Typical boat crew is 3.
They were constructed at the Coast Guard Yard in Baltimore, Maryland, from 1972 to 1979.
