Heesen’s YN 19480 Project Cosmos was launched at the shipyard in Oss on November 19. The 80m superyacht has a gross tonnage of 1,700GT. She is the biggest and fastest all-aluminium yacht ever built.

She is impressive for its immense size and a remarkable top speed of almost 30 knots. This is achieved thanks to the lightweight and low-drag hull design by Heesen’s naval architects on an iteration of the Fast Displacement Hull Form devised by van Oossanen, and assembled, millimetre-perfect, by Heesen’s welders.
Ensuring sufficient longitudinal strength was one of the biggest technological challenges facing Heesen’s engineering team, who designed and patented the Backbone – an intricate, full-length structural reinforcement system. Power comes from traditional, if highly refined, diesel propulsion – four engines, two gearboxes, variable-pitch propellers and ultra-innovative Promas rudders.

Cosmos’s clean lines, a sporty silhouette and the extensive use of glass create a timeless, dynamic profile which were made by renowned British studio Winch Design. “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,” said Jim Dixon, Director of Yachts and Aviation at the British design house.

Sinot Yacht Architecture & Design was responsible for the light and soothing interior design that makes guests feel at home from the moment they step aboard. While the overall palette is neutral, splashes of a range of blue hues are infused into the design throughout. The piece de résistance is undoubtedly the beach club, with its side and stern platforms. The backlit onyx bar with centrally positioned seating is the focal point of this ample and airy space close to the water. With the size, weight and performance of Project Cosmos so intimately connected, Sinot collaborated closely with Heesen’s in-house engineers to ensure that their stringent weight calculations were always met.

“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.”
Following her launch, Project Cosmos will remain at Heesen for commissioning before undergoing intense sea trials in the North Sea commencing in February. She is scheduled for delivery in April 2022.

The construction of the innovative Sialia 45 yacht at the shipyard in Poland is proceeding according to plan. A major achievement has been marked with the completion of the hull and deck. The first fully electric Sialia 45 is expected to be unveiled in June, with its official debut taking place at the Cannes Yachting Festival in September 2025. With its advanced battery system, the yacht boasts a range of 55 nautical miles at 25 knots using standard batteries, while the endurance pack extends this range to over 130 nautical miles. Furthermore, it features rapid charging, allowing the batteries to reach 90% capacity from 10% in just over 2.5 hours.As work progresses on the Sialia 45, the hull and deck have been successfully finished, and the bottom liner is nearing completion, signifying a crucial phase in the production process. One standout feature is the use of cutting-edge carbon technology in constructing the hull. Employing three distinct infusion techniques, the lightweight yet durable carbon-fiber composite achieves optimal performance and longevity. The full carbon sandwich epoxy construction ensures structural integrity and minimizes noise and vibrations, delivering a smooth and comfortable experience.With the target completion date set for late June, Sialia Yachts is confident about meeting their production goals. Once the first unit is delivered, manufacturing will ramp up to produce an impressive ten vessels annually. According to Milvio Ricci, Chief Commercial Officer at Sialia Yachts, this meticulous approach reflects the company's commitment to quality and attention to detail.The Sialia 45 promises unmatched power and efficiency. Powered by dual 300 kW motors, the 14-meter electric cruiser can attain speeds of up to 43 knots. Featuring top-tier amenities, spacious interiors, and versatile deck designs, the yacht is designed for extended journeys without compromising speed. Using the standard 500 kWh battery pack, the Sialia 45 can travel 55 nautical miles at 25 knots, while the optional 200 kWh endurance pack increases this range to 77 miles.For even greater flexibility, the yacht can be equipped with either a 140 kW or 350 kW biodiesel range extender, extending the range to 164 or 240 nautical miles, respectively. Fast-charging capabilities ensure minimal downtime, enabling users to quickly recharge the batteries from 10% to 90% within 3.5 hours—even with the enhanced endurance pack installed.Offered in three distinct models – Runabout, Sport, and Weekender – the Sialia 45 caters to diverse needs. The Runabout model incorporates a sleek, low-profile windshield and open deck layout inspired by traditional motorboats. Meanwhile, the Sport variant adopts a center console configuration with a protective windscreen and roof, offering shelter from the elements. The Weekender version features a glass deckhouse that can transform into a climate-controlled indoor-outdoor space, perfect for warmer or cooler climates.Each model boasts a well-designed lower deck, including a full-spec bathroom with a shower and an optional galley or salon area. Multiple seating arrangements, expansive sun pads, and customizable finishes allow owners to tailor their yacht to suit their preferences, whether they seek a functional pleasure craft or a luxurious superyacht.Sialia Yachts prioritizes sustainability across every aspect of design and production. Beyond the eco-friendly electric drivetrain, the company utilizes recycled materials such as cork flooring and emphasizes lifecycle considerations. These measures reduce environmental impact while ensuring high-quality craftsmanship.
