The YT-86-class harbor tugboat was a wood-hulled tugboat design ordered by the U.S. Navy during World War I.[2] 15 ships of the type were launched and completed, 12 as harbor tugs (Nos. 86-90 and 92-99) and three as ambulance boats (Nos. 91, 100, and 101 were designated as Ambulance Boats No. 1, No. 2, and No. 3).[3] All were launched at the Mare Island Naval Shipyard in Vallejo, California except for one (No. 90) at the Pearl Harbor Naval Shipyard in Hawaii.[3][4] In 1920, after the Navy's adoption of alpha-numeric hull designations, the ships were classified as yard tugs YT-86 though YT-90 and YT-92 through YT-99 and ambulance boats YH-1, YH-2, and YH-3.
