Update: The Mad Decent Boat Party has been cut short, with the boat now heading back to Miami. Rolling Stone spoke to Coast Guard lieutenant commander Gabe Somma, who said 24-year-old Kaylyn Rose Sommer of Charleston, South Carolina dropped from a height of 80 feet while the Norwegian Pearl cruise ship was moving. She went overboard at approximately 6:15 EST. 

"Search conditions are good. The seas are only two feet," Somma told Rolling Stone. "Our concerns are there is a 24-year-old woman in the middle of the ocean with no life jacket."

The woman is missing after allegedly intentionally diving off of a Norwegian Pearl cruise ship, host to the Mad Decent Boat Party, while en route to Mexico Thursday (November 12).

The Pearl set sail on November 11 from Miami. The ship has suspended the mobile festival—which included sets by DiploSkrillex, A-Trak and Diplo's other project Major Lazer—and initially turned around to join in a rescue mission, according to NME. The site says the United States Coast Guard was notified when the vessel was 20 miles off the coast of Cuba, and according to a statement from Mad Decent, additional rescue boats have been deployed.

"The search for the guest is ongoing," the statement reads. "Both the ship and charter company teams are providing support to the family and all impacted guests during this difficult time."

The festival, which was intended to last until November 15, boasts six stages and nearly 3,000 fans, according to the event's website. Adults ages 18 and older are eligible to attend, but those between 18 and 21 can drink beer or wine while on board only if a parent grants consent.

A Norwegian cruise line security guide encourages passengers to alert the company if they notice any missing persons.

"We ask that you please timely report any incident to vessel management," it reads. "Failure to do so may prevent a thorough collection of information and evidence."
