A superyacht carrying British tech tycoon Mike Lynch and his family sank off the coast of Sicily during a sudden nighttime storm. While 15 people were rescued, Lynch and his daughter are among the six still missing. The incident highlights the dangers of severe weather, particularly tornadic waterspouts, which are a potential but unusual culprit in the sinking. The yacht’s design, with a tall mast and retractable keel, may have contributed to its instability during the storm, while the extreme ocean temperatures may have amplified the storm’s strength.
