Dutch boatbuilder Heesen has launched YN 20750, known as Project Orion, at its Oss shipyard on December 6. The yard says this 50-metre all-aluminium hybrid yacht, with a gross tonnage of under 500GT, represents a combination of Dutch engineering and precise construction. Scheduled to be available for cruising in the first half of 2025, the vessel accommodates up to 12 guests across six staterooms.
Ruud van der Stroom, Heesen’s chief commercial officer, says, “Project Orion presents a rare opportunity for discerning clients to acquire a superyacht that embodies the unrivalled safety and solidity of Dutch craftsmanship, ready to cruise by spring. To have immediate access to such exceptional quality – engineered for both style and security – is truly extraordinary. By summer, Project Orion will be poised to navigate the oceans, setting a new standard for luxury.”
Part of Heesen’s 50-metre FDHF aluminium series, Project Orion incorporates hybrid propulsion technology. The series is known for integrating advanced designs with efficiency and sustainability.
The yacht features a Fast Displacement Hull Form (FDHF), developed by naval architects Van Oossanen. Paired with lightweight aluminium construction, this design allows for a compact machinery configuration that enhances propulsion efficiency.
The propulsion system includes twin MTU 12V 2000 M61 (IMO III) engines, each delivering 600kW, achieving a top speed of 16.3 knots. When cruising at 12 knots, the yacht consumes 98 litres of fuel per hour (excluding hotel load), while hybrid mode reduces consumption to 45 litres per hour at 10 knots.
The exterior design, created by Frank Laupman of Omega Architects, features a near-vertical bow and large floor-to-ceiling windows.
These elements help to blend the yacht’s aesthetic appeal with functionality, offering effective navigation through waves and maximising the available natural light.
The interior, by Italian designer Cristiano Gatto, is designed to make the most of sunlight and wide ocean views. The layout includes six staterooms, with a master suite on the main deck, a full-beam VIP cabin, and four staterooms on the lower deck. Open bulwarks contribute to the spacious design and enhance the connection with the sea, making the yacht suitable for both private and charter use.
Heesen will now begin commissioning the yacht’s systems and will prepare for North Sea testing by mid-February 2025.
