Dutch shipyard Heesen has announced the official delivery of the superyacht Cinderella Noel IV. This 50-meter (164-foot) hybrid yacht, previously known by its project name YN 20150, successfully completed intensive sea trials in the North Sea before being handed over to its delighted owners.
Cinderella Noel IV is built on proven engineering platform as a smart custom yacht, so her exceptional performance is no surprise. She exceeded all expectations during three days of sea trials in the North Sea, even in rough weather conditions.
Working on a familiar engineering ground allowed Heesen and the owners’ team to direct their efforts and attention to the fine details. It represented the ideal springboard for these experienced clients, allowing the shipyard to create a dream machine with the best possible balance between quality, customisation, and delivery time.
To minimise the vessel’s environmental impact, the owner has opted for a hybrid propulsion system that embraces the best of 21st-century technology. Heesen’s hybrid system offers incontrovertible advantages over traditional diesel propulsion and will ensure that Cinderella Noel IV is cleaner, quieter, and more efficient than comparable conventional crafts.
The hybrid drivetrain can draw on diesel engines and electric motors for both propulsion and hotel needs. In automotive engineering, such systems emphasize energy saving and reducing emissions, but hybrid propulsion at sea has broader aims. Silent cruising and minimal vibration enormously enhance comfort levels on board and are especially appealing during night passages.
The heart of the hybrid system is the yacht’s twin MTU 8V4000 M63 (IMO Tier III) main engines, each coupled to a water-cooled, 135kW Danfoss electric motor on the same propeller shaft. Thanks to its three cruising modes, this configuration offers versatility of operations, flexible power management, and redundancy.
