Heesen has shared the shipyard’s latest news – the construction of YN 20150, code-named Project Oslo24, has officially begun. The owners and their family attended the keel-laying ceremony on October 4, and welded their ‘good luck coins’ to section three, where the IMO number was engraved. The ceremony was formally witnessed by a Lloyd’s Register surveyor who signed off this first stage in the yacht’s build.

The 50m yacht will be built on the platform of the 50-metre Steel Class. Project Oslo24 will be equipped with Heesen’s hybrid system, which offers indisputable advantages over traditional diesel propulsion. The owner, an experienced yachtsman, made this choice with the clear intent of creating a yacht that is cleaner, quieter and more efficient than comparable conventional craft.

“We were the first shipyard who dared to take the financial risk of building hybrid yachts on speculation and today, all our yachts are available with hybrid propulsion as an option. ‘Be the change you want to see in the world’ is our mantra. Today, that change is real. It is a pleasure to see that clients trust our systems and decide to implement them in their highly customised yachts to reduce their footprint,” says Friso Visser, Heesen CCO.

The Heesen hybrid drivetrain draws on diesel engines and electric motors, together or individually and in any combination, for both propulsion and hotel needs. In the automotive world such systems typically emphasise energy-saving and reducing emissions, but hybrid propulsion at sea has a broader set of aims. Silent cruising and minimal vibration enormously enhance comfort levels on board and are especially appealing during night passages.

The interior is made by Luca Dini Design and Architecture who creates an interior that incorporates plenty of fine details connected to their life at sea and the areas they will be exploring aboard their yacht. Contrasting dark, high-gloss and light matte wood finishes, with a ribbed canneté texture to evoke the forests, blend with soft leather in warm tones to create a snug environment to offer guests a refuge when the air is brisk and chilly outside.

“The owner of Oslo24 and his family are deeply involved in every aspect of this project,” said Stefan Zucker of Zucker and Partner, the owner’s representative. “For us, this makes it an even more exciting project.”
The heart of the system is the yacht’s twin MTU 8V4000 M63 (IMO Tier III) main engines, each one coupled to a water-cooled, 135kW Danfoss electric motor on the same propeller shaft. This streamlined configuration offers versatility, flexible power management, and redundancy, with three operational modes: Silent, Economy and Cruising.

YN 20150 Project Oslo24 is scheduled for delivery in March 2024.

Heesen Yachts is a Dutch ship building company that specializes in custom-built superyachts in aluminium and steel from 30m to 70m in size. Founded in 1978, it has launched more than 170 yachts since its inception.

Azimut has introduced the Seadeck 6, the first model in its new Seadeck Series, at the Venice Boat Show 2024. This series represents the world's first range of low-emission yachts, designed to balance luxury with sustainability. Today the shipyard shared brand new exterior shots of Seadeck 6. Let's take a look. Azimut's Seadeck Series is the result of over two decades of innovation aimed at reducing environmental impact. The Seadeck 6 embodies these efforts, incorporating advanced technologies to deliver one of the most efficient and sustainable yachts produced by Azimut. The series can reduce CO2 emissions by up to 40% compared to traditional yachts of similar size, thanks to its innovative design and technology.The Seadeck 6 measures 17.5 meters in length with a beam of 5.05 meters. It can accommodate up to six guests in three cabins and includes a crew cabin. Powered by Volvo IPS engines, the yacht can reach a top speed of 33 knots and comfortably cruise at 24 knots.The exterior design by Alberto Mancini features a modern aesthetic that blends with the yacht’s sustainable mission. Interior designers Matteo Thun and Antonio Rodriguez focused on using natural or recycled materials to enhance the yacht's durability and aesthetic appeal. Their design includes oak ribbing wood, which contributes to the yacht's longevity and creates a tranquil atmosphere through patterns of light and shadow.The Seadeck 6 features a composite hull and superstructure with carbon fiber reinforcements. Approximately 40% of the yacht's surface, including the deckhouse, roof, wings, bathing platform, and main deck, is constructed using high-performance, lightweight materials. This significant use of carbon fiber helps optimize the yacht's weight, reducing fuel consumption and emissions.The yacht's naval architecture, developed by Azimut|Benetti Group's R&D Department in collaboration with NAMES, maximizes efficiency at cruising speeds. The hull is designed to start hydroplaning sooner, reducing drag and broadening the speed range for optimal efficiency.The Seadeck 6 introduces the Mild Hybrid Zero Emission Hotel Mode, which uses a 42-kWh lithium battery pack and an alternator connected to one of the engines. This system allows the yacht to operate at zero emissions at anchor for up to 4 hours during the day and 8 hours at night. It also enables navigation with the generator off for up to 8 hours, enhancing energy efficiency.The yacht is also prepared for a Full-Hybrid system, which will debut with the larger Seadeck 7 in September 2024. This system will further reduce emissions and improve efficiency.The Seadeck 6 emphasizes the use of sustainable materials. Cork, sourced sustainably, replaces traditional teak for decking. Inside, carpeting is made from recycled materials (R-PET), contributing to a luxurious yet environmentally friendly interior. Approximately 30% of the yacht's skeleton is also made from R-PET, utilizing about 15,000 recovered plastic bottles.Azimut Yachts is an Azimut Benetti Group brand.
