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.

[2] 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;[3] Barbour Boat Works of New Bern, North Carolina;[4] and Western Boat Builders Corporation, Tacoma, Washington[5] 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.
