Summary

What happened.

Before dawn on 19 August 2024 the sailing yacht Bayesian was knocked down and foundered in a sudden, violent windstorm half a nautical mile off Porticello, Sicily. Of the 22 people aboard, seven died. The MAIB's interim report found the yacht was vulnerable to high winds and that, once heeled past about 70 degrees, recovery was impossible.

ConditionsSudden, violent localised windstorm; yacht knocked down.
Lessons learned

What it teaches.

  • 1
    In violent wind a tall-rigged yacht can be knocked down fast. Know your boat's stability limits and reduce exposure when severe squalls threaten.
  • 2
    Watch for sudden, localised severe weather. Have a plan to secure the yacht and account for everyone aboard before it arrives.
    communications
  • 3
    Past a critical angle of heel, recovery may be impossible. Closing hatches and openings early preserves what stability remains.

About SeaWise records: We catalogue sailing emergencies with structured metadata and link to primary sources rather than republishing them. Individual crew names are anonymised by default— sources we link to may name them publicly; SeaWise refers to roles ("the skipper", "the crew") on our pages. Submitter identities are always private.
