In 1972, "Storis" underwent a major renovation converting her from a light icebreaker to a medium endurance cutter. With the change in designation, there also came a change in primary duties. The primary functions of "Storis" shifted to enforcing laws and treaties of the domestic and foreign fisheries in the Bering Sea and Gulf of Alaska. "Storis" underwent another major maintenance overhaul in 1986 that replaced her power plant and expanded her living quarters to include a new berthing area for women and a lounge for the crew.
