Seven people missing with US schooner in South Pacific
Authorities have grave concerns for passengers aboard missing vessel
Searchers said on Thursday they have grave concerns for seven people aboard an American schooner that has been missing for three weeks between New Zealand and Australia.
Maritime New Zealand said on Thursday that searches by plane this week found no sign of the 70-foot (21-metre) wooden vessel named Nina, which was built in 1928.
Authorities say there are three American women and three American men aged between 17 and 73 on board. Also aboard is a British man, aged 35.
The boat left the Bay of Islands in northern New Zealand on May 29. Authorities say the last communication was on June 4, when the Nina was about 370 nautical miles west of New Zealand.
Steve Rendle, a spokesman for the Rescue Coordination Centre New Zealand, said authorities were first alerted to a potential problem on June 14, when they were contacted by concerned family members of the crew.
A storm that day saw winds gusting up to 110 kilometres (68 miles) per hour and waves of up to 8 metres (26 feet).
