All four South Koreans who were trapped inside the ship, called Golden Ray, have now been rescued.
They were the last of the 24 people who were on the ship at the time of the incident, and everyone is now safe.
The U.S. Coast Guard said they extracted three of the remaining four crewmembers on Monday afternoon from the propeller shaft room near the ship's stern.
But one of the four was in a different area, and so another plan was needed to get him.
A fire had impeded the rescue process at first, but it was put out Monday morning, allowing the Coast Guard to drill through the ship's hull to find the missing four.
Then the rescuers rappelled down from a helicopter into the hull and found the first three safe.
South Korea's Consul General of Atlanta was at the scene and said in a briefing after the initial rescue that by talking with the first three they were able to indirectly verify that the other man was still alive.
He was rescued later in the day, at around 6 PM, from behind glass in the ship's engineering compartment where he was trapped.
All four rescued are in good condition and being examined in hospital.
"I think they were pretty relieved. I don't have information on what they said. I know they looked super happy to be outside of that space and coming down onto the tugboat."
The Golden Ray had left the Port of Brunswick early Sunday, headed for Baltimore, but just about a kilometer and a half from the coast it started listing heavily.
It's not clear why it tilted over, but the authorities are investigating the incident.
