Heesen launches largest all-aluminium yacht to date

Heesen Yachts has launched the largest all-aluminium yacht ever built from its Oss-based shipyard. Project Cosmos is 80 metres long, with a gross tonnage of 1,700GT and a top speed of almost 30 knots. Due for delivery to her owners in 2022, the yacht has been constructed throughout the pandemic and arrives on schedule.

The speed top of 30 knots with the sheer size of the vessel is achieved thanks to the lightweight and low-drag hull design.

Ensuring sufficient longitudinal strength was one of the biggest technological challenges facing Heesen’s engineers. They designed and patented what has been called the “Backbone” – a full-length structural reinforcement system.

Power and steering comes from four diesel engines, two gearboxes, variable-pitch propellers and Promas rudders.

“Today, we are celebrating the launch of a unique yacht,” said Heesen CEO Arthur Brouwer. “Unique not only for our shipyard, as she is the largest we have ever taken on and represents the pinnacle of our achievements to date. Cosmos is also unique in the industry – the largest and fastest aluminium yacht in her class ever built.”

Project Cosmos’ exterior has been designed by UK-based Winch Design. Jim Dixon, Winch’s director of Yachts and Aviation, said: “The Winch vision for Cosmos was to retain Heesen’s sporty DNA but blend it with an innovative, futuristic spin. Curved glass forms smooth, sculpted shapes, creating a feeling of slick, contemporary charm.”

Meanwhile, Sinot Yacht Architecture & Design took on the interior design of Project Cosmos. The piece de résistance, according to heesen, is the beach club, with its side and stern platforms.

Following her launch, Project Cosmos will remain at Heesen for commissioning before undergoing intense sea trials in the North Sea commencing in February. She will be delivered to her owners in April 2022.
