A Royal Caribbean cruise ship passenger falls overboard on a trip to Hawaii

A passenger on a Royal Caribbean cruise ship went overboard during a voyage from Australia to Hawaii, a company spokesman confirmed to CBS News on Wednesday.

A Royal Caribbean spokesman said the ship’s crew is working with local authorities on search and rescue operations. Quantum of the Seas departed Brisbane on April 12 and was scheduled to arrive in Honolulu on April 28.

The shipping company did not specify when or where the ship was when the guest fell overboard. However, a US Coast Guard spokesman told CBS News Wednesday night that around 11:00 p.m. Tuesday night Hawaii-Aleutian Standard Time, he received a report of a man falling overboard about 500 nautical miles south of Hawaii’s Big Island. The Coast Guard responded and conducted five searches in about six hours, the spokesman said, but the man was not found.

Another search will be conducted at dawn Thursday, the Coast Guard spokesman said.

A passenger aboard the Quantum of the Seas took to social media early Wednesday to report the incident.

“Three medical emergencies and now a man overboard,” passenger Joshua Reynolds wrote on Facebook. “We’ve slowed down and are now turning around. Hopefully they’ll be found.”

CBS News has also reached out to Australian officials.

In December, a Cruise passenger died after falling off the MSC Meraviglia about 18 miles off the coast of Port Canaveral, Florida.
