Deep-sea divers with Italy’s firefighter corps resumed their search on Tuesday for six missing passengers — including a British software mogul and his daughter — of a yacht that sank off the coast of Sicily the previous day.
Twenty-two people were on board the 180-foot British-flagged sailing yacht, the Bayesian, which was anchored near the port of Porticello, when it was hit by what witnesses described as a waterspout, a small tornado on water, during a sudden and violent storm.
Fifteen people who managed to get to a raft were rescued by the captain of a nearby sailing cruise ship. The body of the yacht’s cook, identified by news outlets as Recaldo Thomas, a Canadian Antiguan, was recovered on Monday. But several people are still unaccounted for, according to Salvatore Cocina, an official with Sicily’s civil protection agency.
Those still missing are Mike Lynch, a British technology entrepreneur; his daughter Hannah; Jonathan Bloomer, chairman of Morgan Stanley International; his wife, Judy Bloomer; Christopher J. Morvillo, a lawyer at Clifford Chance; and his wife, Neda Morvillo.
Mr. Lynch was acquitted of fraud in a U.S. trial in June, ending a high-profile, decadelong legal battle against accusations that he had defrauded Hewlett-Packard when he sold his company, Autonomy, to Hewlett for $11 billion.
Mr. Lynch and the others went missing days after Mr. Lynch’s co-defendant at the fraud trial, Stephen Chamberlain, a former vice president of finance at Autonomy, was fatally struck by a car on Saturday while out for a run, his lawyer, Gary S. Lincenberg, said in a statement.
Prosecutors in the Italian city of Termini Imerese, east of where the yacht sank, are opening a formal investigation into the yacht’s sinking. Reached by telephone, the chief prosecutor declined to comment.
The search for the missing passengers began on Monday but was suspended late that night as crews found themselves limited to the bridge deck and items like furnishings “obstructing passage,” the firefighters’ corps wrote on social media.
When divers resumed the search on Tuesday, ships trawled the waters near the site, the corps said in a statement. The Italian Coast Guard also said in a statement that search operations were “continuing unabated,” with the deployment of helicopters. There was no evidence that gasoline was leaking from the yacht, the Coast Guard said.
The yacht was lying on its right side in about 165 feet of water, meaning that divers, working in pairs, could stay underwater for only about 12 minutes at a time, said Luca Cari, a spokesman for the firefighters’ corps.
Divers were seeking a safe point of access to the vessel’s cabins. “Obviously, everything fell and the space is very tight,” Mr. Cari said, adding that the divers were having to remove obstacles, like furnishings and electrical wiring, that were “completely blocking passages.”
The firefighters’ corps said in a statement that it was impossible to verify whether people were inside the hull.
Mr. Cari said that several divers had been part of the search-and-rescue operations when the Costa Concordia, a cruise liner, capsized off the Tuscan island of Giglio in 2012, killing 32 people. It is considered one of the worst maritime disasters in modern Italian history.
“It’s like the Costa Concordia, but much smaller,” Mr. Cari said in a telephone interview, comparing the search operations. “In the Costa Concordia, we came across many obstacles but we somehow were able to overcome them. Here, the obstacles block the passages and have to be removed.” He added, “This makes it more difficult.”
Crews were also trying to raise the yacht, which experts will examine to try to determine why it sank. Until then, experts can only hypothesize what happened.
Karsten Borner, the captain of a ship, the Sir Robert Baden Powell, which picked up the Bayesian’s 15 survivors, said in an interview that when the wind picked up around 4 a.m. Monday, the Bayesian was about 490 feet behind his vessel. Once the wind wound down, he said, he could not see the yacht anymore.
“My theory was that she was capsized first and then went down over the stern,” Mr. Borner said.
Dario Boote, a ship structures and naval architecture professor at the University of Genoa, said: “Now I imagine that a whole series of lawsuits will be triggered, obviously to ascertain whether there is any responsibility, as always happens very unpleasantly in these situations.” He said, however, that in this case, responsibility might be hard to determine. “Clearly, only once the wreck is raised will we know more,” he added.
Several fishermen told Italian news outlets that they had witnessed a waterspout. Peter Inness, a meteorologist at the University of Reading, said they were relatively common in the Mediterranean, though their occurrence and intensity are unpredictable.
“Until one actually forms, you can’t start telling people where it is,” Mr. Inness said, or “how to get out of the way.”
The inclement weather — with lightning intermittently streaking through the sky — made it hard to know exactly why the yacht sank. Col. Attilio Di Diodato, director of the Italian Air Force’s Center for Aerospace Meteorology and Climatology, said the agency had registered intense lightning activity and strong gusts of wind in the area at the time the boat sank.
The Bayesian had one of the tallest aluminum masts in the world, according to its builder, Perini Navi. “Having a tall aluminum mast would not make it the safest port to be in case of a storm,” said Andrea Ratti, associate professor of nautical design and architecture technology the Politecnico di Milano. The type of intensity unleashed by a violent lightning storm “could have created a significant shock wave,” he added.
He, too, cautioned that “a lot of questions will remain until we have other elements at our disposal.”
Modern yachts are built to withstand meteorological events of reasonable intensity, and all international naval registers suggest that new ships be designed for higher waves and more frequent and extreme weather events.
But “this seems a case of an unreasonable extreme event,” said Emilio Fortunato Campana, an expert in Naval Hydrodynamics at Italy’s National Research Council. “In that case, no ship is 100 percent safe,” he added. “I think the Titanic showed that nothing is unsinkable.”
