Riva 76 Perseo Super Coming This Summer This Summer will see the the completion of the first hull of the Riva 76 Perseo Super. If the name might have a distant ring then you are not mistaken. Riva already built a Perseo model before and this is the new updated version of that. The first hull of the Perseo Super has already been sold too. The exterior design is a collaboration between the Product Strategy Committee led by Mr. Piero Ferrari, designer Mauro Micheli - the founder of Officina Italiana Design with Sergio Beretta - and the Ferretti Group Engineering Department.
