Heesen turns heads with ‘Project MAXIMUS’ and ‘Avanti’

Heesen Project MAXIMUS Superyacht

Heesen announces new 83-metre concept 'Project MAXIMUS' as well as collaboration with Winch Design on the 66-metre Superyacht 'Avanti'.


Heesen’s new revolutionary 83m concept designed by Clifford Denn is maximus by name, and maximus by nature. Project MAXIMUS is 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 ideally suited to optimise the benefits of Heesen’s new ‘shed’, which can house up to 83m LOA.

Inspired by Denn’s experience designing commercial passenger vessels for Cunard (QM2), P&O and, in particular, Viking Ocean Cruise 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 bating 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 five guests, with the option to be configured as 2 x VIP and 1 x guest by opening linking doors, in addition to a stunning Owner’s suite.

“When compared with other boats of its size it has an enormous pool, huge external deck areas, and all with the same internal volumes as a normal 83m,” says Denn. “It’s large boat thinking that puts the Owner’s needs first.”


Winch Design is delighted to be working with Heesen to design the exterior and interior of Avanti, a new 66m motor yacht. The sculptural surfaces of the concept reflect the sky and ocean, creating a muscular contemporary appearance. By incorporating a raised pilothouse, a sporty profile is achieved as well as an Owner’s cabin with panoramic views, overlooking the relaxation area on the foredeck. Dynamic architecture emphasises the elegant sheer line which connects the strong bow to an inviting transom. The stepped aft deck area harmonises interior and exterior living, creating easy access to the infinity edge pool and surrounding waters.

The fresh, contemporary interior features a full beam main deck, filled with plenty of light thanks to the panoramic windows. The infinity pool measures 5 metres and a large tender garage under the fore deck accommodates a limousine tender and rescue boat. Various customisable cabin options are available to suit different desires, and the lower deck offers a full spa option, with gym, Hamman and sauna. The owner’s stateroom connects to a private sky lounge aft, opening up to an exterior dining table. Guests can enjoy a private relaxation area fit with Jacuzzi and bar on the yacht’s spacious sun deck, which is connected to the other 3 decks via a glass elevator. With lounges on 2 levels, and both exterior and interior dining for up to 12 guests, family living and relaxation are at the heart of this Winch Design concept.
