After looking for him around the ship to no avail, she said, she notified the cruise line, which began an hourslong search that ended with the U.S. Coast Guard
rescuing 29-year-old Grimes from the water later that day around 8:30 p.m. after he had gone overboard.
James Michael Grimes spent approximately
20 hours stranded at sea.
Grimes, who was found about 20 miles south of Southwest Pass, Louisiana,
told PEOPLE magazine in December that he remembered having some drinks and winning an air-guitar competition before waking up in the water. He did not respond to interview requests from USA TODAY.
While the incident ended with his safe return to shore, it raised questions about cruise ship overboard detection systems – a new technology that aims to cut down on response time and notify the crew as soon as someone goes overboard.
