The sinking of the $40 million superyacht Bayesian off the coast of Sicily has led to the deaths of seven out of 22 onboard, including British tech tycoon Mike Lynch and his 18-year-old daughter, Hannah. The yacht encountered a waterspout, causing it to capsize rapidly, though the exact cause remains under investigation. Giovanni Costantino, CEO of the yacht's manufacturer, blamed human error, suggesting that proper safety procedures were not followed. Experts have pointed to the yacht's partially retracted keel and its tall aluminium mast as potential factors contributing to the instability. The search continues for Hannah Lynch, with debris and difficult conditions hindering progress. Questions remain about why the Bayesian sank so quickly while nearby boats survived the storm.
