Numerical investigation on optimum trim envelope curve for high performance sailing yacht hulls

A numerical investigation is conducted in order to identify optimum trimming attitudes for resistance reduction in the application of high performance sailing yacht hulls. A lumped parameters model based on general unsteady equations of motion is developed and implemented in combination with a numerical scheme to conduct parametric studies and predict the overall performances of a specific sailing hull. Existing semi-empirical formulas for hydrodynamic coefficients are modified and applied in order to extend the speed range of application and obtain good agreement with available experimental data. Brief discussion of the numerical results is presented with emphasis on the possible applications in the field of modern sailing yachts.
