HONG KONG — Rescue teams were searching the waters between Australia and New Zealand on Friday for a schooner carrying seven people after their boat went missing in stormy seas.

Three passengers on the boat, the Dyche family from Florida — David A. Dyche, 58; his wife, Rosemary, 60; and their son, David — were on their last sailing trip as a family before David, 17, was to leave for college, according to the Web site of The Australian.

The boat, named Nina, left New Zealand for Australia across the Tasman Sea on May 29, and the crew was last heard from on June 4, when one of the people on board, Evi Nemeth, 73, sent a text message to Bob McDavitt, a meteorologist in New Zealand, saying, “Any update 4 Nina? ... Evi.” The message followed a call from Ms. Nemeth saying, “The weather’s turned nasty, how do we get away from it?”

On that day, the Tasman Sea was hit by 65 mile-per-hour winds and swells as high as 26 feet.

Rescuers learned on June 14 that the boat was missing and a search began Wednesday, but there have been no signs of the schooner. No distress signal was received by rescue organizations.
