Design & Optimization of Lamination of a High Speed Boat Exceeding 50kn

Sammanfattning

This thesis presents a Genetic Algorithm (GA) for the optimization of single-skincomposite laminates in the bottom panels of a 12-meter high-speed motor yacht(Maco Pollo, 50 knots), in full compliance with ISO 12215-5. The objective wasto minimize the structural weight while maintaining bending and shear complianceabove a conservative threshold, taking into account practical manufacturingconstraints such as hand lay-up and the use of industrially available materials.The GA was designed to generate symmetric and mirror-balanced stacking sequencesand was tested on critical panels in the bow, stern, and midship regions.The results demonstrate up to 25% weight reduction compared to RINA-basedreference laminates while achieving full ISO compliance. All panels were verifiedthrough an ISO-based MATLAB tool and reviewed by engineers at the collaboratingcompany NavalDesign&Consulting.The developed framework combines theoretical optimization with practicalmanufacturing realism and is adaptable to other vessel types. Although prototypemanufacturing was beyond the project’s scope, the results are ready for industrialimplementation and further development.
