PORTICELLO, Sicily — British tech magnate Mike Lynch and five other people were missing after their luxury superyacht sank during a freak storm off Sicily early Monday, Italy's civil protection and authorities said. Lynch's wife and 14 other people survived.

Lynch, who was acquitted in June in a big US fraud trial, was among six people who remain unaccounted for after their chartered sailboat sank off Porticello, near Palermo, sometime after 4 am. A tornado over the water known as a waterspout had struck the area overnight, said Salvo Cocina of Sicily's civil protection agency.

One body was recovered, and police divers spent the day trying to reach the hull of the ship, which was resting at a depth of 50 meters (163 feet) off Porticello where it had been anchored, rescue authorities said. They returned to the site after 10 pm to see if it would be possible to search through the night, when weather conditions were expected to worsen, said Luca Cari, spokesman of the fire rescue service.

The ship had a crew of 10 people and 12 passengers, the Italian coast guard said. A sudden fierce storm had battered the area overnight, and a waterspout struck precisely where the 56-meter (184-foot) British-flagged Bayesian had been moored.

"They were in the wrong place at the wrong time," said Cocina, noting that another big ship nearby, the Sir Robert Baden Powell, wasn't as badly damaged and helped rescue the 15 survivors — including Lynch's wife, Angela Bacares.

The Bayesian was notable for its single 75-meter (246-feet) mast — one of the world's tallest made of aluminum and which was lit up at night, just hours before it sank. Online charter sites listed it for rent for up to 195,000 euros (about $215,000) a week.

One of the survivors, identified as Charlotte Golunski, said she momentarily lost hold of her 1-year-old daughter Sofia in the water, but then managed to hold her up over the waves until a lifeboat inflated and they were both pulled to safety, Italian news agency ANSA reported. The father, identified by ANSA as James Emslie, also survived, said Cocina.

Karsten Borner, the captain of the Sir Robert Baden Powell, said he had noticed the Bayesian nearby during the storm but after it calmed he saw a red flare and realized the ship had simply disappeared, ANSA and the Giornale di Sicilia newspaper reported. Borner said he and a crew member boarded their tender and found a lifeboat with 15 people, some of them injured, who they then took aboard and alerted the coast guard.

Eight of those rescued were hospitalized while the others were taken to a hotel. One body believed to be the cook was found near the wreck, but six others were unaccounted for and believed inside the hull, said Cari, the fire rescue spokesperson. The rescue operations, which were visible from shore, involved helicopters and rescue boats from the coast guard, fire rescue and civil protection service.

Cocina said the crew and passengers hailed from a variety of countries: In addition to Britain and the United States, passengers and crew were from Antigua, France, Germany, Ireland, Myanmar, the Netherlands, New Zealand and Spain, he said.

The UK Marine Accident Investigation Branch is deploying a team of four inspectors to Italy to conduct a preliminary assessment. The Foreign Commonwealth and Development office said it was "providing consular support to a number of British nationals and their families."

Dutch foreign ministry spokesperson Casper Soetekouw said the lone Dutch citizen on board, a man, had been rescued and was not in life-threatening condition.

Lynch, once hailed as Britain's king of technology, was cleared in June of fraud and conspiracy charges related to Hewlett Packard's $11 billion takeover of his company, Autonomy Corp.

The not guilty verdicts followed an 11-week criminal trial in San Francisco that delved into the history of HP's 2011 acquisition of Autonomy, a business software firm founded by Lynch.

The fraud accusations represented a dramatic turn in the fortunes of an entrepreneur once described as the Bill Gates of Britain — a title he seemed to live up to when he netted an $800 million from the Autonomy sale.

The acquittal vindicated Lynch, who had vehemently denied wrong doing and portrayed HP as a technological train wreck.

"I'm looking forward to returning the UK and getting back to what I love most: my family and innovating in my field," Lynch said in a statement released after the verdict.

The yacht, built in 2008 by the Italian firm Perini Navi, can accommodate 12 passengers in four double cabins, a triple and the master suite, plus crew accommodations, according to Charter World and Yacht Charters.

The vessel, which previously was named Salute when it flew under a Dutch flag, featured a sleek, minimalist interior of light wood with Japanese accents designed by the French designer Remi Tessier, according to descriptions and photos on the charter sites.
