MIAMI -- An Orlando man who jumped from a cruise ship off Florida's coast Friday was rescued about eight hours later by the Coast Guard, according to authorities.

Michael Mankamyer, 35, waved his arms at crews when he was found at about 8:45 a.m., Coast Guard Petty Officer Jennifer Johnson said. He was airlifted to a hospital and the Coast Guard reported that he suffered from mild hypothermia but was otherwise in good condition.

"He's alive," Coast Guard Petty Officer Dana Warr said. "We found him."

The ship reported that Mankamyer had jumped from the balcony in his room and into the water around 12:45 a.m., a Coast Guard statement said. A witness said Mankamyer was intoxicated, Warr said.

Mankamyer was aboard the Carnival Glory, which operates out of Port Canaveral east of Orlando, according to the cruise company's Web site.

After the cruise ship alerted authorities, it stayed in the area to assist with the search, Warr said.

"The time that they did spend was appreciated," Warr said.

Warr said that ship and another cruise that assisted in the search left the area before Mankamyer was found.

Carnival spokesman Tim Gallagher said no additional details were immediately available.

The ship was en route to Nassau, The Bahamas, its scheduled port of call, according to Carnival.
