Service life edit

Arivaca was assigned duty in the 12th Naval District and remained so occupied until the middle of 1955. At the beginning of the summer of 1955, the tug was deactivated preparatory to being loaned to some organization whose identity is not now known. The transfer appears to have taken place in November 1955, and the loan lasted almost two years. In October 1957, the tug returned to active service in the 12th Naval District. In February 1962, Arivaca was reclassified a medium harbor tug and was redesignated YTM-259. Two years later, on 17 February 1964, Arivaca was sold by the Navy and renamed Sea Hawk, Official Number 294212.
