Investigators have concluded that the Bayesian yacht sank on August 19, 2024, off the coast of Sicily not due to a storm but because of crew negligence and improper safety measures. The vessel sank near Palermo at around 5 a.m., resulting in the deaths of Mike Lynch, his daughter Hannah, and five others.
The investigation revealed that the weather conditions at the time were manageable, amounting to little more than a squall. Italian prosecutors stated that the crew’s improper actions and underestimation of the weather contributed significantly to the sinking.
An interim report indicated that wind speeds reached 63.4 knots, which were sufficient to capsize the yacht. Investigators noted that “the Bayesian should have been able to handle the powerful weather.” However, vulnerabilities in stability information were not identified in the stability information book carried on board.
The investigation raised the possibility of criminal negligence against the captain and two crew members involved. The exact reasons for their improper actions remain unclear.
Key facts:
- The Bayesian superyacht sank on August 19, 2024.
- Seven people died in the incident.
- The vessel was 56 meters (184 feet) long.
The Bayesian was recovered from the sea ten months after its sinking in June 2025. This tragic event was intended as a celebration of Mike Lynch’s recent acquittal in a fraud case. The Marine Accident Investigation Branch continues its work to ensure accountability and improve safety measures for future maritime operations.
