USCGC Bitt (WYTL-65613)

USCGC Bitt (WYTL-65613) was a cutter in the US Coast Guard. Constructed by Western Boat Builders Corp. and commissioned in 1966, the vessel served as part of the USCG for sixteen years before being decommissioned in 1982 and transferred to the National Science Foundation (NSF). During her Coast Guard service Bitt was based in Washington and Alaska where she was utilized mainly in a law enforcement and search and rescue (SAR) role. She is still in active service as a research vessel with the NSF.

Construction and design
Crewed by five personnel, Bitt was a small vessel displacing 74 tons. She was 64 ft long, with a beam of 19 ft and a 9 ft draft. The vessel's main drive engine consisted of one Caterpillar D379 V-8 diesel which produced 400 shaft horsepower and drove a single propeller, giving a cruising speed of 7.0 kn and a cruising range of  3690 nmi. Her maximum speed was 10.6 km, at which she could patrol 1130 nmi. She carried no armament, but was fitted with a SPN-11 detection radar. Upon completion she cost a total of $US 158,366 to construct.

History
Bitt was one of fifteen steel-hulled icebreaking small harbor tugs that were put into service in the 1960's to replace 64 foot wooden-hulled harbor tugs that the Coast Guard had used since the 1940's. She was initially homeported at Bellingham, Washington where her duties included law enforcement and SAR as well as ice operations. On 5 January 1969 she assisted in the evacuation of a stranded person near the Nooksack River when a dike broke. On 29 July 1969 she towed the disabled fishing vessel Jet Stream to safety from Admiralty Inlet. On 20 October 1975 she rescued two persons from a capsized sailboat. She transferred to Valdez, Alaska in 1978. She was decommissioned in October 1982 and transferred to the National Science Foundation for use as the Research Vessel Clifford A. Barnes. She is currently in service through an agreement with the University of Washington School of Oceanography research facilities at Seattle Washington.
