UIM president Dr. Raffaele Chiulli and the world of powerboating, reunited in Lugano (Switzerland) for the third stage of XCAT World Series, mourn the loss of Muhammad Ali: “UIM – says Dr. Chiulli - will honor today in Lugano one of the greatest man in sports history, who always distinguished himself both on ring and outside for his commitment and battles in civil society. Today, during the Emaar Pole Position at the World Championship UIM XCAT on the waters of lake Lugano, all the drivers, who are coming from all over the world for this stage, will perform a slow lap in memory of Muhammad Ali. ‘Float like a butterfly and sting like a bee’: world sports will be ever with you, and you will be our legend forever”.
