ISA's 141 Super Sportivo After unveiling the 121 SuperSport at last year's Monaco Yacht Show (MYS), ISA Yachts also hinted at a larger model, the 141 Super Sportivo. More information has come to light regarding this particular new model. It will be their largest fiber glass-built model for the Italian brand. Like the 121, the 141 is designed by Marco Casali. The design is sleek and her lines give a fast-moving appearance even if she is at anchor.
