The Bayesian collapse: Two years on – shipyard in insolvency, unanswered questions

The sinking off Porticello

On the evening of 18 August 2024, the “Bayesian” was moored off Porticello on the north coast of Sicily. During the night, the yacht listed severely in strong winds and sank. Among the seven fatalities were the British entrepreneur Mike Lynch and his 18-year-old daughter Hannah. Fifteen people survived the disaster, including Lynch’s wife, Angela Bacares.

According to the the UK Marine Accident Investigation Branch (MAIB) There were twelve passengers and ten crew members on board. The ship sank about half a nautical mile south-east of Porticello.

According to the reconstructions carried out so far, the yacht capsized within a matter of seconds. However, the reason why it was unable to withstand the weather remains the subject of two investigations.

MAIB sees a lack of stability

In May 2025, the MAIB published an interim report. It is based explicitly on the material available at that time and not on a full investigation of the wreckage. The authority therefore emphasises that the findings may still change in the light of new evidence.

British investigators have reached the preliminary conclusion that the ‘Bayesian’ may have been at risk from strong winds under certain operating conditions. An investigation commissioned by the MAIB found that the yacht could become unstable when facing crosswinds at speeds of between approximately 53 and 63 knots. Once the heel exceeded an angle of approximately 70 degrees, the situation was no longer controllable.

The key point here is the context: the MAIB has not reached a final determination of liability. Its investigation is intended to prevent future accidents, not to assign legal responsibility. The interim report should also be reviewed in the light of further investigations following the recovery of the wreckage.

YACHT had already analysed the technical findings of the report in detail. The Findings of the first investigation report on ‘Bayesian’ They therefore continue to form an important basis for the debate on design, stability and operational condition.

The Italian public prosecutor’s office is investigating the crew

Alongside the MAIB’s safety investigation, a criminal investigation is being conducted in Italy by the public prosecutor’s office in Termini Imerese. This investigation is also examining possible errors on the part of the crew. The focus is on Captain James Cutfield, the chief engineer Tim Parker Eaton and crew member Matthew Griffiths.

According to Italian media reports, the public prosecutor’s office’s experts have a different assessment of the weather conditions on the night of the accident to that of the MAIB. According to these reports, the strength of the wind alone may not have been the decisive factor. Investigators are also examining whether the crew responded adequately to the changing weather conditions and whether certain measures were taken too late or not at all.

This account does not, as yet, constitute a final judicial finding. All those accused are presumed innocent. Nor is the MAIB interim report an expert opinion on liability, and it cannot replace the criminal assessment in Italy.

The wreck was salvaged in 2025 and taken to Termini Imerese. There, it was expected to provide investigators with further clues about the final minutes of the voyage. Investigations into the vessel were still ongoing in June and July 2026. As of 18 August 2026, no public confirmation had been given that the Italian investigation had been definitively concluded. The MAIB also continues to treat the case as an ongoing investigation.

The developer in judicial crisis proceedings

The financial situation of Italian Sea Group is the second major new aspect of the case. The company, which owns the Perini Navi brand, applied to the relevant court in July 2026 for proceedings under Article 44 of the Italian law on crisis and insolvency. The court initiated the proceedings with the aim of enabling the business to continue operating.

It is difficult to assess the extent to which the collapse of ‘Bayesian’ has affected the economic situation. However, in its claim against the owners and crew members, the company itself cited losses in turnover, reputation and share price as damages.

The claim for 456 million euros

Italian Sea Group – or, more specifically, the shipyard responsible for the yacht’s construction – is claiming 456 million euros in civil proceedings. The claim is directed against Angela Bacares, the yacht’s owner company, Captain James Cutfield and two other crew members.

According to the company’s account, errors in the operation of the yacht are said to have contributed to its sinking. Among other things, the company cited the handling of weather warnings, openings that were left open or not adequately secured, and the operational condition of the yacht. These allegations are the subject of the proceedings and have not been legally established.

For its part, Bacares has brought claims against the Italian Sea Group. It remains to be seen what impact the judicial crisis proceedings will have on the mutual claims. Insolvency or court protection does not automatically bring such proceedings to an end, but it may affect the enforcement and order of priority of claims.

The YACHT had the Lawsuit for 456 million euros against the owner analysed as early as January 2026. The shipyard’s new financial status is now altering the context in which this legal dispute is being conducted.

No evidence of sabotage

The sinking has sparked widespread speculation due to Mike Lynch’s background and the circumstances of the voyage. Some reports have suggested possible links to intelligence services and acts of sabotage as possible scenarios.

There is as yet no conclusive evidence to support this. In its interim report, the MAIB explicitly stated that it had not included unverifiable information or speculation in its investigation. Nor do the publicly available details of the Italian investigation provide any conclusive evidence of external interference.

The outstanding questions are therefore primarily of a technical and operational nature. These include the yacht’s exact operating condition, the wind and wave conditions, the crew’s response, and the question of what information the crew had regarding the yacht’s stability.

What is clear two years later

It is a fact that the ‘Bayesian’ sank on the night of 19 August 2024 and that seven people died. It is also a fact that the MAIB is investigating a possible structural weakness and that the Italian public prosecutor’s office is investigating possible negligence on the part of the crew.

It is not clear, however, which cause was decisive from a legal and technical perspective. The MAIB interim report is provisional. As of 18 August 2026, the Italian investigation had not yet been publicly concluded. Furthermore, Italian Sea Group is not simply ‘bankrupt’, but is undergoing judicial reorganisation proceedings with the stated aim of continuing operations.

This means that, even two years after the sinking, the case remains unresolved.

​Book recommendations

Heavy-weather sailing Peter Bruce’s book examines the behaviour of sailing and motor yachts in heavy weather, the causes of instability, and how to prevent capsizing. The book thus explores the technical and seamanship aspects of the ‘Bayesian’ case in greater depth. The fully revised 15th edition was published in 2025 and comprises 400 pages.

Yacht accidents Jan-Erik Kruse classifies typical accident scenarios and their causes on the basis of accident reports from around the world. Topics covered include rough seas, capsizing, water ingress, man-overboard situations and the impact of human error. The title adds the perspective of accident prevention and risk management to the article.
