Parametric design for hydrodynamic optimization purposes: The case of "Symiaki skafi"

The objective of this study is to provide a comprehensive analysis of the parametric design and hull optimization of a traditional Greek vessel known as the "Symiaki skafi". This vessel is distinguished by its unique characteristics, especially its hull geometry, which will be examined and analyzed in detail. The methodology of the manuscript is innovative. Initially, the relevant parameters affecting the design of the vessel's lines plan are delineated. Then, the positions of the control points for the parametric curves are determined. The subsequent development of the parametric surface of the model is founded on these parametric curves. The manuscript culminates in a comparative assessment of the basic hydrostatic values of the parametric model with those of the original vessel, prior to the hull optimization. This work is of dual significance in the context of decarbonization in shipping. On the one hand, it is a study of a traditional wooden vessel, which by definition has a low carbon footprint. On the other hand, it optimizes its hydrodynamic behavior so as to make it seaworthy and operationally efficient.
