Post-war she continued serving Pearl Harbor ships until she was decommissioned in May 1973, and eventually sold for "scrap" to Crowley, in San Francisco.

In 1989, after the Loma Prieta earthquake in the SF Bay area, Nokomis and Hoga (which had been serving the City of Oakland as a fireboat) fought fires alongside each other again.

[2] Nokomis was decommissioned and was stricken from the Naval Vessel Register in May 1973 and sold by the Defense Reutilization and Marketing Service to Crowley Maritime Corporation in September 1974.

[5] According to the Historic Tugboat Education and Restoration Society, the Nokomis was purchased in April 1975 by Crowley Maritime Corporation, and her name was changed to Sea Serpent.

Crowley Maritime terminated their operations in the San Francisco area in the early 1990s and the Nokomis was reflagged Panamanian and abandoned along with many other tug boats, to decay and rust.

The YC-699 barge on the SF Bay and the YT-153 tug on the east coast, with Hoga, are now the last remaining Naval Pearl Harbor surviving vessels.
