Heesen Yachts celebrates the delivery of Solemates (YN 20655), a fully customized 55-meter steel superyacht, to an experienced owner who has chosen the Dutch shipyard for the second time. This milestone underscores Heesen’s reputation for engineering excellence, build quality, and the flexibility of its speculative build program – enabling clients to personalize proven platforms without compromising on time efficiency.
Built on Heesen’s successful 55m Steel design, Solemates combines the proven Fast Displacement Hull Form (FDHF) by Van Oossanen Naval Architects with Omega Architects’ sleek exterior lines. The owner, a seasoned yachtsman, leveraged the platform’s inherent reliability to focus on tailored interior enhancements that reflect a family-oriented approach to cruising.

Rupert Connor of Luxury Yacht Group noted: "While the changes from the previous model appear subtle, the cumulative refinements across the entire platform elevate this yacht significantly. Heesen’s commitment to continuous improvement shines through."
The owner’s deep yachting expertise and hands-on involvement ensured a streamlined build process. Ralf Oortman, Heesen’s Project Manager, remarked: "Their team’s insight into the client’s lifestyle was invaluable. We collaborated seamlessly to introduce standout features, such as the breathtaking atrium – a true masterpiece that sets Solemates apart."
Working alongside Silvia Margutti of Luca Dini Design and Architecture, the owner reimagined the interior with vibrant accents, a redesigned main staircase featuring gold-flaked acrylic panels, and an expanded sundeck hot tub area for social gatherings. Every detail was meticulously crafted to enhance onboard living.
Following flawless sea trials in the North Sea, Solemates confirms her robust performance and efficiency. With a 760 GT volume, she offers ample space for extended cruising while maintaining the comfort and reliability expected of a Northern European build.

Solemates will be available for exclusive charter through Luxury Yacht Group, with her world premiere set for the 2025 Monaco Yacht Show, where she will headline Heesen’s display.
Niels Vaessen, Heesen’s CEO, reflected: "Delivering Solemates to a repeat client is a testament to our craftsmanship and the trust owners place in us. This project exemplifies how we blend efficiency with bespoke luxury – creating yachts that exceed expectations."
