A French fishing boat will arrive later than the estimated time of 11 a.m. PDT Saturday (2 p.m. EDT, 1800 GMT), said Jeff Casher, an adviser to Abby Sunderland's solo quest to sail around the world. He was not sure how long the delay would be.
Australian search-and-rescue teams spotted Abby drifting in the frigid, rough Indian Ocean, her sailboat damaged by 30-foot (9-meter) waves that prompted her to set off a distress signal.
After a tense 20 hours of silence Thursday, a search plane launched from Australia's west coast made radio contact with Sunderland on Friday morning.
Her boat's mast was broken — ruining satellite phone reception — and was dragging with the sail in the ocean, said search coordinator Mick Kinley, acting chief of the Australia Maritime Safety Authority that chartered a commercial jet for the search.
But the keel was intact, the yacht was not taking on water and Sunderland was equipped for the conditions, he said.
"The aircraft (crew) spoke to her. They told her help was on the way and she sounds like she's in good health," Kinley told reporters in Canberra.
"She's going to hang in there until a vessel can get to her."
A lifelong sailor, Sunderland had begun her journey trying to be the youngest person to sail solo, nonstop around the world — a record briefly held last year by her brother — and continued her trip after mechanical failures dashed that dream.
She told searchers Friday that she was doing fine with a space heater and at least two weeks' worth of food, family spokesman William Bennett said. Casher said the boat had gotten knocked on its side several times.
The seas were rough late Friday, with 20- to 24-foot (6- to 7-meter) waves at her last known location, according to Shaun Tanner, senior meteorologist at data provider Weather Underground.
Abby's father, Laurence Sunderland, thanked the Australian rescuers' quick response in sending out a search plane.
He rejected criticism that it was far too dangerous to allow a 16-year-old to sail around the world by herself.
"Sailing and life in general is dangerous. Teenagers drive cars. Does that mean teenagers shouldn't drive a car?" Laurence Sunderland told the AP. "I think people who hold that opinion have lost their zeal for life. They're living in a cotton-wool tunnel to make everything safe."
Abby's brother, Zac, himself a veteran of a solo sail around the world at age 17, said he told his sister to be prepared for storms and other problems. He said it's in her nature to handle those calmly.
"I think Abby is quite a conqueror, quite level-headed," her brother said on ABC's "Good Morning America" on Friday.
But renowned Australian round-the-world sailor Ian Kiernan said Abby should not have been in the southern Indian Ocean during the current southern hemisphere winter.
"Abby would be going through a very difficult time with mountainous seas and essentially hurricane-force winds," Kiernan told Sky News television.
Conditions can quickly become perilous for any sailor exposed to the elements in that part of the world.
Sunderland — whose father is a shipwright and has a yacht management company — set sail from Los Angeles County's Marina del Rey in her boat, Wild Eyes, on Jan. 23. She soon ran into equipment problems and had to stop for repairs. She gave up the goal of setting the record in April, but continued.
On May 15, Australian 16-year-old Jessica Watson claimed the record after completing a 23,000-mile (37,000-kilometer) circumnavigation in 210 days. Watson and her family sent a private message of hope to Sunderland's family, spokesman Andrew Fraser said.
Friday's communication with Abby was the first since satellite phone communications were lost early Thursday.
She had made several broken calls to her family in Thousand Oaks, California, reporting her yacht was being tossed by 30-foot (9-meter) waves — as tall as a 3-story building. An hour after her last call ended, her emergency beacons began signaling.
The search plane — a chartered Qantas Airbus A330 jet that left Perth early Friday — jet faced a 4,700-mile (7,600-kilometer) round trip from Perth to Sunderland's boat, which is near the limit of its range.
Qantas spokesman Tom Woodward said the airliner flew five hours to reach the area where the beacons were transmitting, then maneuvered for another hour before spotting the 40-foot (13-meter) yacht. In all, it hovered over the site for two hours, Qantas said.
The Australian maritime authority did not say how much the rescue mission would cost but said it would not be seeking compensation for the search, which initially fell just outside of Australia's search and rescue region.
"That's the way the system runs," search coordinator Kinley said. "It's our obligation to do this and we'll fulfill those obligations as Australia does."
The CROSS maritime rescue center on the island of Reunion, off Madagascar, said it had sent three boats in her direction.
Philippe Museux, CROSS director, told French RFO television station in Reunion that it had asked a fishing boat to head to the zone.
On Wednesday, she wrote in her log that it had been a rough few days with huge seas that had her boat "rolling around like crazy."
Information on her website said that as of June 8, she had completed a 2,100-mile (3,400-kilometer) leg from South Africa to north of the Kerguelen Islands, taking a route to avoid an ice hazard area. Ahead of her lay more than 2,100 miles (3,400 kilometers) of ocean on a 10- to 16-day leg to a point south of Cape Leeuwin on the southwest tip of Australia.
