Allocated to the 1st Naval District for net tending duty in the Boston Harbor area she was reclassified AN–33 on 20 June 1944.

Through the spring of 1945 Nutmeg was engaged in maintaining and repairing net defenses in Boston Harbor.

In May she was attached to Commander Task Force 24 for the purpose of maintaining the anti-torpedo net in Placentia Harbor, Argentia, Newfoundland.

Nutmeg had been scheduled for duty at Pearl Harbor when she departed Boston, Massachusetts, 21 July for transit to the U.S. West Coast via Key West, Florida, the Panama Canal Zone, and San Pedro, California.

Voyage repairs and a main engine casualty necessitated a change in schedule, and when World War II ended, Nutmeg was placed on the inactive list and shifted to the Columbia River Reserve Basin.
