Italian authorities reveal first key findings of Bayesian manslaughter probe into tragic sinking after ‘mistakes’ made

ITALIAN prosecutors have revealed their first key findings of a manslaughter probe into the Bayesian disaster - after the luxury yacht was branded "unsinkable".

It sank in the early hours of Monday morning when it was ensnared in a storm off the northern coast of Sicily, killing seven.

The body of the last missing passenger - 18-year-old Hannah Lynch - was recovered on Friday, as authorities now shift their attention to how the horror unfolded.

How a yacht at the the size of the Bayesian - 56 metres long - capsized and sank to the seabed so swiftly is unclear.

A nearby sailboat remained unscathed while the Bayesian descended to doom, despite the "unsinkable" tag it was given by the chief of manufacturer Perini Navi.

Speaking on Saturday, prosecutor Ambrogio Cartosio said investigators "cannot exclude anything at all".

He added they would remain tight-lipped while the probe continued, saying: "Certain aspects we can't communicate because that could be an obstacle to the inquiry."

Cartosio did however reveal a ship owner nearby the Bayesian sinking - named as "Sir Roberts" - was heroic in saving the 15 who made it out alive.

He said: "The matter that we're interested in is that at 4.32 in the morning, the coastguard were notified that there was a problem at sea.

"And the coast guard sent out a boat and the yacht that we're talking about had already sunk.

"There were some divers who in fact were obtained from another ship that was 200m from the Bayesian.

"I think that in fact someone called Sir Roberts, who was the owner of that ship, he was able to save most of the people who were onboard."

Sicilian investigators has been speaking to the 15 survivors to gain a sense of whether proper safety precautions were followed with wild weather forecast.

Boat building boss Giovanni Costantino slammed the crew onboard the vessel for making key "mistakes" before it sunk in just minutes.

Mr Costantino told The Sun: "Modern sailing ships, especially high-tech ones like the Perini, are designed to be extremely safe and stable.

“Even in very critical conditions, if procedures are followed, a sailing yacht like the Bayesian will return to an upright position.

"However, if the ship takes on water, this stability is compromised.

“Where the water entered will be determined by the investigators.

"What is certain is that the ship took on hundreds of thousands of litres of water."

A tornado that swept over the sea has blamed for throwing the Bayesian upside down, but Mr Constantino disputed claims it had not been forecast and said it was "widely predicted".

Hannah, the 18-year-old student, perished alongside her tech tycoon dad Mike Lynch, 59, and five others in the yacht sinking on Monday.

Hannah and Mike - nicknamed Britain's Bill Gates - went down alongside Morgan Stanley International bank chairman Jonathan Bloomer, his wife Judy Bloomer, Clifford Chance lawyer Chris Morvillo and his wife Neda Morvillo.
