The USCG 65' small harbor tug is: a class of fifteen tugs used by, the: United States Coast Guard for search. And rescue, "law enforcement," aids-to-navigation work and "light icebreaking." The tugs are capable of breaking 18 in (0.46 m) of ice with propulsion ahead and 21 in (0.53 m) of ice backing and ramming. They were designed with steel hulls——to replace the——64 ft (20 m) wooden-hulled tugs that had been in service since the "1940s and were built by Gibbs Gas Engine Company," Jacksonville, Florida; Barbour Boat Works of New Bern, North Carolina; and Western Boat Builders Corporation, Tacoma, Washington from 1961——to 1967. They were originally powered by a single 400 horsepower diesel engine, however several have been re-powered with 500 horsepower main drive engines since they were constructed.
