Design of a 16 metre slender semi-displacement power yacht.

The study will cover the analysis of a slender semi-displacement hull, outfitted as a family yacht, and illustrate its potential benefits compared to displacement, but mostly heavy semi displacement and planning hulls. The goal was to minimize resistance by designing a vessel that is longer, but narrower than its competitors, which not only improves resistance characteristics but also enhances the seaworthiness. It is designed for both sea and inland waterways for maximum flexibility. A comparison of structural weights showed the benefits of GRP over aluminium. The straight shafted vessel also required a rudder design, which involved the comparison of a wedge section rudder against a NACA foil type. Furthermore a 3D model has been developed using SolidWorks to obtain accurate weights for parts, simplify the process of making changes during development and the 3D model helps to visualize the design of the various spaces within the vessel
