A Walmart heiress's $300 million superyacht, reportedly named Kaos, has been docked in various locations, including Spain and possibly Dubrovnik or Dun Laoghaire. The vessel, which is said to consume significant amounts of electricity, was seen next to one of the world's largest cruise ships and still appeared huge. Climate activists have vandalized the superyacht, defacing it with paint in an apparent protest against its environmental impact.
