According to reports from Sky News, an ongoing investigation into Bayesian's sinking found that the bad weather experienced on the night of the disaster was unlikely to have caused the yacht's capsizing.
Sky News reported that experts had been appointed by Italian prosecutors to determine the weather's intensity during the night of the sinking. Their preliminary findings suggested that the yacht's sinking occurred due to the crew's "improper actions", including their underestimation of the weather and certain safety devices not being activated adequately.
