AMS carried out the full structural engineering of YYachts’ Y8, using advanced FEA throughout the entire design process – from concept to detailed lamination plans – enabling the yard to deliver a lighter, more spacious yacht


that will meet both performance and safety standards.


Case Study: the 80ft Cruiser-Racer Y8 by YYachts The advantages of FEA become particularly evident when tackling unconventional structural challenges. Among AMS’s many successful


projects, the 80ft cruiser-racer Y8 by YYachts stands out as a prime example of how advanced simulations can push the boundaries of yacht engineering.


Rethinking Structural Design for More Space and Customisation The Yyachts shipyard, which is always focused on innovation and product improvement, aimed to create a spacious and comfortable open-space saloon inside the yacht. To achieve this, they wanted to offer


the final client an exceptionally high level of customisation, requiring AMS to replace the standard mast-supporting bulkhead layout with a less intrusive ring structure, while still maintaining sufficient structural inertia.


Validating an Unconventional Layout with FEA The proposed solution had potential, but we needed to assess its strength and stiffness with extensive FE analysis. We meshed the geometry and ran the first simulations, revealing two critical issues:


•Initial ring thickness was insufficient to handle the expected loads


•The entire structure was too weak when subjected to grounding loads


(accidental impact with the seabed) To resolve these issues, we:


1. Increased the height of the secondary girders to reinforce the floor framing


2. Modified themesh and re-ran all analyses to ensure the new configurationmet structural requirements


This time, the results were positive


across all validation criteria. The unconventional layout was successfully approved, demonstrating how FEA enables the development of innovative solutions that would be impossible to validate through traditional methods alone.


Conclusions By integrating FEA into every stage of the design process, AMS enables shipyards and designers to push the boundaries of yacht engineering. Our dedication to structural innovation results in lighter, stronger, and more efficient yachts that meet the highest industry standards. Whether optimising a racing yacht, enhancing the structural integrity of a luxury motor yacht, or pioneering new applications in composite materials, AMS remains at the forefront of high-end yacht engineering, delivering expertise that actively shapes the future of the industry. In an increasingly competitive market,


the ability to optimise design is no longer just a technical advantage. It’s a necessity to ensure the success of every new project. Investing in FEA not only guarantees


safety and performance but also provides high-value engineering solutions that can be tailored to customer expectations. This commitment to quality and continuous improvement ensures that yacht designs evolve to meet the growing demands of a rapidly advancing industry. www.ams-italia.it
