Investigators examining the sinking of tech tycoon Mike Lynch’s superyacht in Italy said the vessel was knocked over by "extreme wind" and could not recover, in an interim report published on Thursday.
Entrepreneur Mr Lynch, 59, and his daughter Hannah, 18, were among seven people who died when the Bayesian sank off the coast of Sicily during a storm on August 19 last year.
An interim report into the disaster by the Marine Accident Investigation Branch (MAIB) shows wind speeds of 63.4 knots (73.0mph) on the vessel’s beam were sufficient to tip it over, and it may have been "vulnerable" to lighter winds.
It said that "vulnerabilities" were "unknown to either the owner or the crew of Bayesian" as they were not included in the stability information book carried on board.
