A collaboration between Ben Ainslie Racing Technologies and Pininfarina gave birth to the UK-based Princess Yachts R35 sport yacht, debuting in Cannes this week. America’s Cup technology channeled into the Princess Active Foil System means less drag for the R35, providing stellar stability, comfort, and maneuverability in all sea conditions. Italian car-design firm Pininfarina—known for its work on such marques as Ferrari, Maserati, and Alfa Romeo—designed the lightweight carbon-fiber monocoque hull. Side air blades maximize engine airflow and mange stern turbulence, improving comfort all the while. Two aluminum V-8 engines give the boat a 50-knot top-end speed—the fastest Princess ever. Posh interiors by Princess remind us that it’s a yacht.
