Coast Guard searches for three fishermen whose boat capsized in Hawaii

HONOLULU, July 5 (UPI) -- The Coast Guard rescued three recreational boaters after their vessel sank as they helped in a search for three missing fishermen off Oahu's North Shore in Hawaii.

The boaters' 30-foot recreational vessel was towing a 20-foot fishing boat Monday evening when the U.S. Coast Guard responded to a distress signal. The three men were rescued by helicopter, and a fourth swam to shore.

One is being treated for hypothermia, a Coast Guard statement said Monday.

The search remains in progress for the fishermen, identified as Jensen Loo, Clint Oshima and Derek Tomas, whose boat was discovered overturned early Monday. The Coast Guard is employing the patrol boat USCGC Kiska, a MH-65 Dolphin helicopter and a C-130 Hercules plane in the search.
