Dutch yard Heesen has given a construction update on the 80 metre all-aluminium superyacht Project Cosmos.
The hull and superstructure of the yacht have now been joined, a construction milestone that marks the biggest assembly to take place at the yard.
The event saw the 80.07 metre low-drag hull driven onto a barge and transported across the canal to a quay capable of carrying out lifting operations. A total of four telescopic cranes lifted the hull from the barge and placed it into the water.
The propulsion system, which consists of four engines and two gearboxes, was then installed into the hull. The yacht will now undergo outfitting ahead of its launch in 2021 at which point it will become Heesen's largest yacht to date.

Sold in March 2018 and also known as hull YN19480, Project Cosmos features exterior styling by British studio Winch Design, exhibiting “muscular sportiness and timeless elegance”, with Sinot Yacht Architecture & Design appointed to design the yacht's interiors.
This will be Heesen's third collaboration with Sinot, which also worked on 55 metre Azamanta and 70 metre Galactica Super Nova.
It comes after the keel laying ceremony took place in May. The event was attended by Heesen chief executive Arthur Brouwer who declared Project Cosmos "the fastest and largest aluminium yacht ever built in the world."
A key challenge for the yard has been securing a top speed of 30 knots for the 80 metre superyacht.
To achieve this, the yard had to find a way to add strength to the aluminium, which is thicker than usual, and developed what it has dubbed a "backbone". Thanks to the new techniques used, the yacht is both rigid and lighter.
Project Cosmos will also feature a propulsion package of four MTU 4000 M73 engines totalling 19,000hp.

Other key features include a certified helideck on the bow, which can transform to an outdoor lounging area populated with furniture that emerges from the deck. The tender garage, which is set to feature a Winch-designed custom limousine, sits under the helideck.
The interior styling of Project Cosmos will feature a blend of natural materials, with lighter hues and accents of blue and darker wenge.
It comes after the yard completed tank testing on the project in January
Other decorative materials will include black onyx, straw marquetry and crystal panels while custom furniture made from glass, marble, metal and various woods will add the finishing touches to this highly modern superyacht.
Speaking about the owner, Sinot's vice president of client services Kimberly Stone said: "He did not want anything too shiny. He wanted something very neutral but with some burst of colours as well as beautiful textures."

Another key interior feature is the central staircase which "is shaped like a snail shell or petals of a flower," Sinot design engineer Paul Costerus said.
Heesen sales and marketing director Mark Cavendish also previously revealed that the owner briefed Sinot to create a "lighter, luxurious and comfortable interior" and for ceiling heights to be "as optimised as possible."

Cavendish also previously described Cosmos' beach club as its "piece de resistance". “Drop-down platforms to the stern and side create a truly enormous space, and there is a stunning sunken bar below the onyx and glass clad bottom of the aft deck swimming pool," he said.
Accommodation is for up to 12 guests split across six cabins, including a main deck master suite, bridge-deck VIP and four lower deck cabins. Meanwhile, the crew quarters is suitable for a staff of up to 19 people.
