COSMOS: Heesen's Largest Superyacht to Date


Heesen yachts unveiled its largest yacht to date, 80m Heesen yacht COSMOS. The Dutch shipyard recently celebrated its 40thanniversary and has been very busy. Earlier in 2018, Heesen sold 2 fully custom superyachts to be built in their 22,000 m2 shipyard in Winterskwijk.

The buyers of Heesen yacht COSMOS had 2 simple requests. The mega yacht needed to be 80m in length and travel at a speed of 30 knots. Not only was this a tall order for Heesen, but something they had never done before. The aluminum yacht weighs 500 GT more than the Heesen yacht GALACTICA SUPER NOVA, so achieving the goal speed posed a problem. After a structural feasibility study by van Oossanen Naval Architects, Heesen knew COSMOS would need 4 MTU 20 V 4000 engines. Combined, the engines produce 19,000 horsepower at 3,540kW each! The weight of the engines (roughly 52 tons) and the length of the vessel create structural issues. To combat this, Heesen engineers developed a patented solution they termed “The Backbone”.

The interior space is just as impressive. The award-winning Dutch design studio, Sinot, reached to nature for inspiration. Glass, natural light and well-thought-out ceiling heights create a sense of balance and a clean aesthetic. These details are offset with the use of backlit onyx, crystal glass panels, and straw marquetry. Furthermore, hardwood flooring, silk carpets, natural leather wall paneling, and stainless-steel will set the tone.

The yacht will accommodate 12 guests in four guest suites on the lower deck. A VIP with an adjacent private studio on the bridge deck. The striking master stateroom will be on the main deck forward. Nineteen crew in eleven cabins will be able to discretely service the guests.
