Bayesian was a 56-metre (184 ft) sailing superyacht, built as Salute by Perini Navi at Viareggio, Italy, and delivered in 2008.[7] It had a 72-metre mast, one of the tallest in the world. The yacht was last refitted in 2020.[8] It was in the legal ownership of Angela Bacares, wife of the technology entrepreneur Mike Lynch.[9][10] It was at anchor off the Northern coast of Sicily near Porticello on 19 August 2024, when it was struck shortly before dawn by a powerful storm and sank.[11]

Design and construction

Bayesian was a flybridge sloop designed by Ron Holland[1] and built with a 56 m (184 ft) aluminium hull and a single-masted cutter rig. The 75 m (246 ft) aluminium mast was at the time of construction the world's tallest. The yacht had a retracting keel, allowing its draft to be reduced from 10 m to 4 m.[6] It was one of a number of similar vessels from the same designer and shipyard and was one of the world's largest sailing yachts. The yacht had a traditional aft cockpit and an additional 60 m2 (650 sq ft) fully-encloseable cockpit forward. The interior was outfitted in Japanese style by the French company Rémi Tessier Design.[12] The yacht won best interior at the International Superyacht Society Awards 2008, and best sailing yacht over 45 m at the 2009 World Superyacht Awards.[13]

History

The yacht, allocated IMO Number 9503392, was ordered by Dutch entrepreneur Eric Albada Jelgersma [nl] (1939–2018), but in 2005 he was paralysed in a yachting accident; on completion it was sold in 2008 to Dutch property developer John Groenewoud and named Salute.[1][14][15] In November 2014, it was sold to Revtom Ltd., an Isle of Man company owned by Angela Bacares, wife of the technology entrepreneur Mike Lynch, and renamed Bayesian,[1][15] a reference to Bayesian inference, which was used in statistical machine learning by Lynch's company Autonomy Corporation.[16] From then, the yacht was registered in the United Kingdom, with London as port of registry. It was refitted in 2020 and was managed since 2022 by Camper & Nicholsons International, Geneva.[1][15]

Sinking and aftermath

Sinking

Lynch was celebrating his acquittal in his San Francisco fraud trial and had invited lawyers, friends and associates to join him, his wife and their daughter, on a cruise around Sicily.[17] Bayesian sank shortly before daybreak on 19 August 2024 during a storm when anchored off Porticello, a small fishing village about 15 km (9.3 mi) east of Palermo, Sicily.[17][18]

Data from the tracking of the Automatic Identification System (AIS) showed that at 3.50 CEST Bayesian was already struggling against the storm — or downburst, as the Italian prosecutor later specified — and then began to drag its anchor. At 4.05 the yacht was entirely underwater and a few seconds later its emergency position-indicating radiobeacon (Epirb) became detached from the top of the mast and automatically raised the alarm, which was picked up by the satellite station managed by the Bari Coast Guard.[19] The yacht sank rapidly to a depth of 49 metres (161 ft).[20]

Rescue and recovery

The yacht had been carrying 10 crew and 12 passengers. The fifteen survivors were rescued by the nearby Sir Robert Baden Powell, a smaller Dutch schooner built in 1957. One body was recovered from the sea, while six people remained missing.[21][17] Divers from the fire brigade immediately began searching the wreck. The task was challenging on account of the depth, which limited divers to eight minutes to work on the wreck. They also found access to the cabins was blocked by furniture.[17] Six bodies were eventually recovered from the interior of the yacht on 21, 22 and 23 August.[22][23] The yacht was lying on its right side on the sea-floor, and the bodies of the passengers were found in cabins on the left side where, investigators suggested, they had been taking refuge.[24]

Survivors

The fifteen survivors were Angela Bacares and five guests, captain James Cutfield, and eight other members of the crew.[25][26]

Dead

  • Jonathan Bloomer, chairman of Morgan Stanley International and past chairman of Autonomy Corporation[27]
  • Judy Bloomer, wife of Jonathan Bloomer[27]
  • Mike Lynch, founder of Autonomy Corporation and Invoke Capital[27]
  • Hannah Lynch, daughter of Mike Lynch[23]
  • Christopher J. Morvillo, partner at Clifford Chance US LLP and Lynch's lawyer[27]
  • Neda Morvillo (née Nassiri),[28] jewellery designer and wife of Christopher Morvillo[27]
  • Recaldo Thomas, the yacht's chef[27]

On Sunday 25 August, a special mass and candle-lit vigil were held for the victims in Porticello and wreaths were laid on the sea.[29]

Speculation about causes

In the immediate aftermath of the sinking, there was media speculation about how Bayesian could have sunk so quickly, especially as a nearby yacht was undamaged in the storm. Although early eyewitness accounts led to reports that the yacht had been struck by a waterspout, the Italian authorities said a downburst was more likely. Commentators, while acknowledging that the weather was probably not the only factor in the sinking, said that record high sea surface temperatures around Sicily at the time could have increased the intensity of storms in the area.[30]

There were conflicting opinions about whether the exceptional height of the mast made the yacht vulnerable to capsizing. Giovanni Costantino, chief executive officer of The Italian Sea Group, which now owns the Perini Navi shipyard which built the yacht, defended the design of the yacht, describing it as "unsinkable" and suggested the crew had been at fault. He said the crew should, in the face of the approaching storm, have shut doors and hatches, turned on the engine, lowered the retractable keel and faced the wind. While some experts shared his opinion, others thought that the sinking had been caused by freak weather conditions which the crew could not have foreseen.[30] The seafarers' union Nautilus International cautioned against blaming the crew before the full facts were known, saying it was "not only unfair but also harmful to the process of uncovering the truth and learning any lessons from this tragedy".[18]

Judicial investigation

The chief prosecutor of nearby Termini Imerese, Ambrogio Cartosio, initiated a judicial investigation into the sinking.[22] On 26 August, the captain of the yacht was placed under investigation for charges of manslaughter and shipwreck.[31]

As Bayesian was a UK-registered vessel, the Marine Accident Investigation Branch also opened an investigation into the causes of the sinking and sent a team of four inspectors to Italy.[32][33]

Salvage

The Italian Coastguard said on 22 August 2024 that a decision on whether or not to raise the wreck would be considered later.[34]
