The 50-meter ISA superyacht “Papi du Papi” Italian yacht builder International Shipyards of Ancona, popularly known as ISA Yachts launched its second 50-meter superyacht last year, ISA 500 christened as “Papi du Papi”. This yacht is built on a steel hull with aluminium superstructure bred to take on the deep blue on her own bottom. Her design is distinctly ISA to those who are familiar to this Italian yard’s style. The exterior lines were pencilled by Andrea Vallicelli for ISA while the warm tropical interior was done by Francesco Paszkowski. Not surprising taking into consideration the area of the world owners the are from.
