SANTA CRUZ, Calif. (AP) -- The Pacific Ocean either swallowed an adventurous couple and two young children aboard a sailboat off the Monterey coast this week, or someone played a cruel hoax that wasted Coast Guard resources and tugged at the hearts of coastal residents over two days of desperate searching.
The Coast Guard on Tuesday called off the search for a boat that reportedly sank in rough seas far off the Central California coast, saying nothing more could be done and that the family's distress calls might have been a hoax.
"We've exhausted the possibilities," Coast Guard Chief Petty Officer Mike Lutz said. The Coast Guard is treating the incident as a rescue, with the possibility the calls came from a trickster. Neither the family nor the boat has been reported missing.
Crews started looking for the family by sea and air after receiving their first distress call Sunday afternoon, when the boaters said their 29-foot sailboat was taking on water and their electronics were failing. The 42-hour search involved hundreds of rescuers from the Coast Guard and the California Air National Guard. A Hercules C-130 four-engine turboprop aircraft buzzed above the seas, while helicopters, cutters and lifeboats plied the waters, as costs soared into the hundreds of thousands of dollars.
The sailboat had no working GPS system, but investigators used its radio signal and radar to determine the call came from an area about 60 miles west of Monterey, where strong winter winds, cold water and big swells made for perilous conditions. Forecasters had issued a weekend advisory warning boaters of rough seas in the area.
An hour later, the family members reported they had to abandon the boat and were trying to tie together a makeshift life raft out of a cooler and life-preserver ring, a method taught in survival classes. The Coast Guard then lost radio contact with the boat, which the agency said might have been called the "Charmblow."
The Monterey Bay at this time of year is about 50 degrees; a person could survive between 30 minutes and an hour without a survival suit or wetsuit.
Investigators determined from the broken distress calls that the family included a husband and wife, their 4-year-old son and his cousin, Coast Guard Lt. Heather Lampert has said. But the agency received no reports about a family missing at sea.
On Monday, the Coast Guard released one of the recorded calls in hopes that it would lead to new information from the public that could help in the search.
In the crackling recording, a man's calm voice is heard saying, "Coast Guard, Coast Guard, we are abandoning ship. This is the (Charmblow). We are abandoning ship."
Sailors along this renowned stretch of coastline are a close-knit group who were gripped by the news of the missing family, but also baffled by important omitted details. Harbor masters at the string of ports that dot the coastline from Monterey to Half Moon Bay told The Associated Press the same thing: No boats launched from their docks were missing, and no family had disappeared from their community.
FBI spokesman Peter D. Lee in San Francisco said the agency was not investigating and had received no missing-persons reports that could be this family.
Sunday's choppy conditions had smoothed to flat, glossy seas by Tuesday, and in harbors, neither officials nor boaters had heard of a vessel called "Charmblow." But several noted that boats are registered in California by number, not name. Owners can call a boat whatever they want. Federally registered boats use names, but there was no "Charmblow" listed on the federal database.
Capt. Gene Maly, a 40-year veteran of sailing who runs a charter sailboat out of Monterey, said the entire incident might have been a hoax. But the Czech native, who has logged 80,000 miles at sea, said it's also possible that ill-prepared sailors set out without the proper training and equipment.
"It could be that these people are neophytes and had no clue," he said. "The last thing you want to do is abandon ship."
Maly, who carries backup GPS navigators and extra life vests and radar systems, said he lives by the missive: "Those that do not respect the sea will surely die. Those that respect the sea will only die now and then."
His care is typical in the deceptively mild Monterey Bay, a federally protected marine sanctuary where in just a few minutes, placid blue water can turn to roiling waves, huge sneaker waves surge over gentle currents, and sunny skies can grow dark with fog.
"Very often people underestimate ocean safety," said Hanna Tuson-Turner, a sailing instructor in Half Moon Bay. "Weather systems can come from out of nowhere and equipment can malfunction."
Maritime safety expert Mitchell Stoller, a former Los Angeles harbor pilot and supertanker captain, said several safety items could have meant the difference between life and death: an inflatable life raft, and an electronic position indicating radio beacon, a $200 device that provides rescuers a location.
Coast Guard Executive Officer Noah Hudson in Monterey paused, sighing, on Tuesday when asked how he felt when a search is called off.
"It's tough for me thinking that we had four people out on the water who were in need of rescue, and to think there might have been loss of life in this case, it's tragic."
But if it was a hoax, "it's unfortunate that we were forced to use so many resources for so much time," Hudson said.
Making a false federal distress call is a federal felony, and perpetrators face up to six years in prison and a $250,000 fine. Yet the Coast Guard handles several hundred hoax calls a year, some involving major rescue efforts. Last year a massive search was launched in the Atlantic Ocean east of Sandy Hook, N.J. ,after a caller falsely radioed for help, saying "We have 21 souls on board, 20 in the water."
Kurtis Thorsted, 55, of Salinas, Calif., was released from federal prison last summer after being convicted, for the second time, of making false calls to the Coast Guard. Court records show he made 51 distress calls over five months, claiming in one case to be in trouble in a kayak off the coast of Santa Cruz.
