Interim Report Reveals Wind Vulnerabilities in Mike Lynch’s Sunken Superyacht

The MAIB report confirms extreme winds and undocumented stability flaws as the primary causes of the Bayesian’s 2024 capsize, while ongoing investigations and salvage delays hinder further findings.

The multi-purpose floating work barge Hebo Lift 2 monitors the stretch of sea off Porticello, near Palermo, Sicily, Italy, Sunday, May 4, 2025, where the British superyacht Bayesian sunk on August 19, 2024 as the operations for its recovery start.

Overview

  • The Bayesian superyacht capsized off Sicily in August 2024, killing seven, including tech entrepreneur Mike Lynch and his daughter Hannah.
  • An interim report by the UK Marine Accident Investigation Branch identified extreme winds exceeding 70 knots and undocumented stability vulnerabilities as the key factors in the sinking.
  • The yacht’s stability manual did not account for vulnerabilities in its motoring condition with the centerboard raised, leaving the crew unaware of the risks.
  • Salvage operations, paused since May 9 due to a diver’s death, have resumed to recover the wreck lying in 50 meters of water, critical for the final safety report.
  • Italian criminal investigations continue, restricting access to evidence, as UK inquests examine the deaths and families of victims raise concerns over design and safety failures.
