In a technological leap towards sustainable yachting, Feadship secured a second Approval-in-Principle (AiP) from Lloyd’s Register during the UnIQ on Tour tech-talk on September 28. The AiP was granted for Feadship’s groundbreaking compact multi-fuel system design, a product of extensive research and collaboration with the industry.
This achievement marks a pivotal moment on Feadship’s energy transition roadmap and serves as the foundation for upcoming new-build projects. The focus of the design was to create a compact, resilient fuel system capable of handling low-flashpoint fuels while ensuring safety. The system reflects Feadship’s foresight that the next generation of yachts must be adaptable to the evolving shipping fuel landscape.

The design supports the use of 'methanol,' a prominent choice across global seagoing shipping. Feadship’s multi-fuel system not only accommodates methanol but also ensures compatibility with existing fuels, enabling global operations. It also opens the door to expanding the use of methanol-based fuel cells, promising enhanced energy conversion efficiencies and zero pollutant emissions.
Mattes Kruize, Director Projects at Feadship, emphasized the significance of this step, stating, "For Feadship, this is a significant step that continues on the path that we have charted out."
Engel-Jan de Boer, Global Yacht Segment Director at Lloyd’s Register, praised the potential of Feadship’s methanol fuel system, anticipating its transformative impact on the yacht industry by offering a sustainable alternative to traditional fuels. The AiP provides assurance to owners and operators that the system meets safety and performance requirements, positioning Feadship as a pioneer in clean energy adoption within the yachting sector.
Based in the Netherlands and with roots dating back to 1849, Feadship was formed as a group in 1949 as a marketing partnership between six Dutch shipyards, de Vries Lentch, Van de Stadt, Witsen & Vis, Akerboom, De Vries Scheepsbouw and Van Lent Shipyard, and De Voogt Naval Architects. Feadship is well-known as one of the Netherlands’ most elite yacht builders and delivers superyachts from 50–100+ meters in length.
