Revolutionary design

Our new revolutionary 83-metres concept designed by Clifford Denn is maximus by name, and maximus by nature. This yacht has a hugely flexible platform that offers optimum distribution of both interior and exterior volumes and spaces to achieve a long, low, sleek and narrow vessel.

First impressions

Inspired by Denn’s experience designing commercial passenger vessels where the Wheel house is located forward and under the Passenger decks, this striking yacht puts the owner experience at the fore. Central to the design is the 100 per cent use of private exterior deck for owner and guest, stretching an unprecedented full length of the boat.

An almost vertical bow enables an extended waterline length and so allows the crash bulkhead to move forward, gaining interior space and volume. This frees up further exterior space at the stern of the vessel, including an impressive pool area,

stunning waterfall features and a large bathing platform. Wide stairs link all external decks, and a fantastic cosy covered external lounge/dining area is located just forward of the pool on the Main deck.

Providing good wind protection for all aft decks and optimal hydrodynamic performance for which Heesen is renowned, this flexible platform, packed with Heesen signature details, can accommodate up to twelve guests, with the option to configure four out of the five guest suites into 2 x VIP suites by opening linking doors, in addition to a stunning owner’s stateroom.
