After nearly a week of perusing art and carousing parties in Miami, the wealthy retreated to their yachts for private parties over the weekend. Sugar baron Pepe Fanjul hosted Miami Beach’s new mayor, Philip Levine, Stavros Niarchos and girlfriend Jessica Hart, Alex von Furstenberg, gallerists Nick Acquavella and Adam Lindemann and Dori Cooperman, among others, on his yacht at Sunset Harbor Yacht Club in Miami Beach. Meanwhile, billionaire George Lindemann and wife Frayda threw their own yacht reception for guests including Simon de Pury. And on Saturday tech and nightlife entrepreneur Michael Hirtenstein and wife Christina invited a beautiful crowd to his 150-foot yacht Il Sole at Miami Beach Marina.
