A New Chapter

Fresh from a transformative nine-month refit, Mouna is a full-custom 50-metre Heesen with a fresh look, a new name, and an energy all her own. Originally delivered as Sibelle and recognised at the 2016 World Superyacht Awards, she’s now sharper, sleeker, and smarter – a striking showcase of Heesen engineering and Japandi design philosophy. With beach club, wellness facilities, and thrill-tastic toybox, Mouna is ready to give you the time of your life.
