The appendages’ influence on the hydrodynamic resistance of a sailing vessel
Abstract
A comparative analysis on the hydrodynamic resistance of a sailing vessel with and without appendages was performed using both the experimental model tests results obtained in the Towing Tank of “Dunarea de Jos” University of Galati and the estimations based on the theoretical method proposed by Larson and Eliasson. The following appendages were included: the suspended rudder with large aspect ratio and the keel with additional weight (hydrodynamic profiled). The ITTC 1957 method was used to transpose the model results at full scale. The conclusions reveal the important influence of the appendages’ resistance and the large differences between the theoretical and experimental results.
