Lürssen’s Kismet has arguably one of the most detailed and complex interiors of any yacht. Launched in 2014, the 312-foot behemoth’s interior came from UK designer Reymond Langton, and incorporates a “Champagne and caviar” motif. How that translates into reality is a fusion of styles that range from art nouveau and baroque to Persian and Japanese. The sheer variety of materials are matched with unusual shapes, like a piano set in a metal sculpture, or a stairway of gold, which goes from a lower-level saloon up into the main saloon, so the entertainment area extends across two floors. Dark woods, rich marble, and beautiful metals make this one of the most impressive interiors in the modern superyacht fleet.
