A Hawaiian fisherman is missing again, just a few months after surviving 12 days lost at sea. Ron Ingraham, 67, spent almost two weeks adrift and surviving on raw fish after getting caught in an enormous storm on Thanksgiving. He eventually managed to radio for help and was rescued - but as of Friday Ingraham is missing again, in potentially even more danger than before. According to the U.S. Coast Guard, his ship ran aground on rocks around a mile west of Hawaii's Lanai island. Rescue the first: Ron Ingraham is pictured above in December being welcomed aboard a Navy destroyer after 12 days stranded at sea. He is missing again . Recovery: Pictured above is the sailing boat Ingraham had got lost in, which was towed back to shore by his rescuers . His sailing mate, Kenny Corder, was thrown into the water with him, and the two were clinging to a life ring to survive. Corder, who was rescued and taken to hospital, said that he left Ingraham with the ring to swim backed to the damaged ship and radio for help. By the time he returned, he said, there was no sign of Ingraham - and Coast Guard officials are still looking for him. The Coast Guard notified Ingraham's son in Missouri, Zakary Ingraham, said the son's wife, Katie Jarrett. 'This is absolutely insane,' she said. Long-lost: Pictured above in Ingraham's son, Zakary. The two hadn't spoken in more than 15 years when he went missing the first time . Ingraham and his son had not spoken for years, but news of his improbably rescue in December brought the two back together. He was considered lost after a search triggered by a Mayday message saying he was about to sink did not help authorities track him down. During a routine trip from Molokai island, where he lives, to Lanai, where he often fishes, a huge storm knocked out his engine and pummeled his boat with 20-foot waves. 'I lived off the moisture off the fish I caught,' Ingraham said. 'Mentally, physically and spiritually, I got my butt kicked.' Eventually he got weak and assumed he would die - and friends had already planned his funeral. Man and the sea: This file photo shows Ingraham at sea years ago. His boat ran aground on rocks Friday - his second major difficulty in less than six months . The Coast Guard launched a massive search and he was thought to be dead, until he was able to use a wire hanger to get a signal sent from his battered radio. That led to his rescue by crew members on the guided-missile destroyer USS Paul Hamilton. Meanwhile, another man was also missing from a separate boat around Hawaii after he reported Thursday his vessel was flooding about 10 miles south of Honolulu Harbor. The Coast Guard searched overnight for the mariner who was aboard the vessel Kolea and then suspended the search on Friday afternoon.
