A thorough search along Kaua'i's South Shore yesterday morning by foot, air and jetski failed to find a 36-year-old kayaker who has been missing since Saturday afternoon.

The search for Corey German shifted yesterday afternoon to a "passive" search in which officials would follow up on new information on his possible whereabouts, Kaua'i Fire Chief Robert Westerman said.

German was reported missing about 3:15 p.m. Saturday after lifeguards rescued his wife, Tina, also 36, from a choppy ocean about 400 yards offshore at Po'ipu on Kaua'i's South Shore. The couple had launched a kayak at Koloa Landing earlier that afternoon, said Kaua'i County spokeswoman Mary Daubert.

The Kaua'i Fire Department and the Coast Guard searched for German into the night Saturday and all day Sunday, concentrating on the area between Koloa Landing and Spouting Horn, Daubert said.

Mrs. German was taken to Wilcox Hospital on Saturday. No update on her condition was available yesterday.
