History

edit

Design and construction

edit

Bayesian was built with a 56 m (184 ft) aluminium hull and a single-masted cutter rig. The 75 m (246 ft) aluminium mast was designed for the yacht and at the time was the world's tallest. The ship was one of the world's largest sailing yachts. It featured a traditional aft cockpit and an additional 60 m2 (650 sq ft) fully-encloseable cockpit forward. The interior of the yacht was outfitted in Japanese style by the French design company Rémi Tessier Design.[3] It was voted best interior at the International Superyacht Society Awards 2008 and best sailing yacht over 45 metres at the 2009 World Superyacht Awards.[4]

Name

edit

Originally named Salute, its second and final name, Bayesian, is a reference to “Bayesian Inference”, one of the two main approaches to statistical machine learning and the one that was used by Lynch’s company.[5] This is related to Bayesian probability, derived from the eighteenth century British statistician, Thomas Bayes, and pioneered and popularised by nineteenth century French scholar, Pierre-Simon Laplace.

Sinking

edit

Bayesian sank in the early morning of 19 August 2024, off the coast of Palermo, Sicily. An attorney for Lynch said that the passengers had intended to celebrate Lynch's acquittal on fraud charges with members of his defence team.[6] At the time of the sinking the yacht was anchored off Porticello (township of Santa Flavia), a small fishing village about 15 kilometres (9.3 mi) east of Palermo.[7][8]

The Bayesian sank quickly after capsizing whilst at anchor during a storm and sank to a depth of 50 metres (160 ft). The ship was carrying 10 crew and 12 passengers, of whom 15 were rescued. The body of a crew member has been recovered.[9][10] The remaining six, including Lynch, are missing.

The Italian Coast Guard confirmed the identity of the victims. A team of specialist divers descended to the wreck repeatedly. They reached the main bridge but were unable to search further inside for victims due to furnishings obstructing their passage and the limited dive time of 10 minutes at the wreck.[11][12][13][14][excessive citations]

Survivors

edit

Among the survivors are Angela Bacares, Lynch's wife, and two New Zealanders: lawyer Ayla Ronald, and the captain, James Catfield.[15][16]

Missing

edit

Confirmed deceased

edit
  • Ricardo Thomas, Antiguan citizen born in Canada, crew member of the Bayesian, ship's cook. He is currently the only confirmed fatality.[22]
