The phone calls and texts ended June 4. More than three weeks later, searchers said Thursday they have grave concerns for the crew on the classic 85-year-old wooden vessel that went missing while sailing from New Zealand to Australia. Attempts to contact the crew by radio and an aerial search this week have proved fruitless.
Authorities say the skipper of the 70-foot (21-meter) vessel Nina is American David Dyche. They say there are two other American men and three American women aboard, aged between 17 and 73. Also aboard is a British man, aged 35.
Messages posted online by friends indicate the boat originally left from Panama City, Florida.
Meteorologist Bob McDavitt said he took a satellite phone call from the boat June 3. A woman named Evi asked how to get away from the weather. He said to call back in 30 minutes after he'd studied a forecast. She did.
"She was quite controlled in her voice, it sounded like everything was under control," McDavitt said, adding that the call itself indicated she was concerned about the conditions.
McDavitt said he spoke only briefly to Evi, advising her to head south and to brace for a storm with strong winds and high seas. The next day he got a text, the last known communication from the boat: "ANY UPDATE 4 NINA? ... EVI"
McDavitt said he advised the crew to stay put and ride out the storm another day. He continued sending messages the next few days but didn't hear back. Friends of the crew got in touch with McDavitt soon after that, and then alerted authorities June 14.
Kevin Banaghan, who is spearheading search efforts by Maritime New Zealand's Rescue Coordination Centre, said rescuers weren't worried at first because there had been no distress call from the boat and its emergency locator beacon had not been activated. He said rescuers on June 14 initiated a communications search, in which they tried contacting the boat over various radio frequencies as well as contacting other vessels in the area to see if they'd spotted the Nina.
This week, he said, rescuers escalated their efforts. An Air Force plane on Tuesday searched the area where the boat went missing. A second search by the plane on Wednesday went as far as the Australian coast but again turned up nothing. Banaghan said searchers are considering their next options.
The boat left the Bay of Islands in northern New Zealand on May 29 bound for the port of Newcastle, near Sydney. The last communication was from 370 nautical miles west of New Zealand.
Banaghan said the crew hoped to arrive in Australia mid-June but that, given the conditions, he considered a realistic arrival date to be about June 25. He said Dyche is a qualified captain and the crew has varying degrees of experience.
"We're very concerned for their safety and wellbeing," he said.
Authorities say the storm three weeks ago saw winds gusting up to 110 kilometers (68 miles) per hour and waves of up to 8 meters (26 feet).
Banaghan said the Nina is a "lovely old craft" which won races when it was new and had been maintained in excellent condition. He added that it had a new engine installed in recent months which had apparently created some initial leaking problems.
He said there are several possible scenarios, including the boat losing communications, drifting off course, or the crew taking to lifeboats. He said there's also a possibility the boat suffered a catastrophic failure and sank before anybody had time to react.
