... and variants covering the resulting design space have been generated and evaluated. Dependencies between the design parameters and rudder characteristics at different operating conditions have been established and used for further optimization. reservoir surveillance variant vortice boundary layer...

... large moments, provide a number of complex challenges for designers. Assessing seakeeping behavior and performance in a seaway is, indeed, important during the design process since the motions cause unsteady effects on the yacht hydrodynamic characteristics, for instance on the lift generating...

... the results of the present work and previous experimentation, with motion in earth axes, showed similar trends. However the results from the experiments using motion in body axes showed marked changes in the measured motion and resistance characteristics when compared to the earth axes data. It is thought...

... attention to use of computerized flow simulation methods for improving hydrodynamic performance. This paper highlights characteristics of methods capable of predicting sailboat hydrodynamic drag forces. Taken together the resistance components predicted include appendage surface friction drag, configuration...

.... Three foil shapes have been designed and it is shown that their hydro­dynamic characteristics are very much dependent on location and mode of boundary-Layer transition. The planform parameter which strongly affects the capabilities of the keel to achieve laminar flow is lea ding-edge sweep angle...
