The second Iona (YTB-220), a wooden tug originally classified YT-220, was launched by Greenport Basin & Construction Co., Greenport, N.Y., 26 August 1944; sponsored by Mrs. Martina E Swanson; and placed in service 2 February 1945.
The new tug was assigned harbor duty in the 14th Naval District, based at Pearl Harbor, and she remained there until transferred to the Philippine Islands in 1956. At Subic Bay Iona performed harbor duties so necessary for the smooth functioning of a great naval base and was reclassifled YTM-220 in February 1962. In June 1963, following accidental sinking in May, she was disposed of by burning.
