Crewed by five personnel, Bitt was a small vessel displacing 74 tons.^[2] She was 64 ft 11 in (19.79 m) long,^[4] with a beam of 19 ft 1 in (5.82 m) and a 9 ft (2.7 m) 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,^[4][3] giving a cruising speed of 7.0 kn (13.0 km/h; 8.1 mph) and a cruising range of 3,690 nmi (6,830 km).^[2] Her maximum speed was 10.6 kn (19.6 km/h; 12.2 mph), where she could patrol 1,130 nmi (2,090 km).^[4] She carried no armament but was fitted with a SPN-11 detection radar.^[2] Upon completion, she cost a total of $US 158,366 to construct.^[4]

Bitt was one of fifteen steel-hulled icebreaking small harbor tugs that were put into service in the 1960s to replace 64 ft (20 m) wooden-hulled harbor tugs that the Coast Guard had used since the 1940s.^[5] She was initially homeported at Bellingham, Washington where her duties included law enforcement, SAR, and ice operations.^[4][5] On 5 January 1969, she assisted in evacuating a stranded person near the Nooksack River when a dike broke.^[5] On 29 July 1969, she towed the disabled fishing vessel Jet Stream to safety from Admiralty Inlet.^[5] On 20 October 1975, she rescued two persons from a capsized sailboat.^[5] She transferred to Valdez, Alaska in 1978.^[4][5] She was decommissioned in October 1982 and transferred to the National Science Foundation for use as the Research Vessel Clifford A. Barnes. After serving through an agreement with the University of Washington School of Oceanography research facilities in Seattle, Washington, the University of Washington decommissioned the vessel at the end of 2018. She was purchased at auction by a civilian couple in 2019, who renamed her back to Bitt. The couple currently live aboard her with their child in Northern California.^[3][6][7]
