Abstract: In the course of increase of the requirements, the necessity of more precise rudder cavitation forecasts becomes obvious. Especially for vessels with alternating operation conditions (e.g. short sea shipping) the design conditions are not easy to define. The practice of performing model tests is not able to cover the influence of the occurring operation conditions. Therefore the following approach gives an opportunity to benchmark different rudder designs regarding cavitation in the expected operation conditions. The rudder design itself can be improved by optimising the shape of the rudder sections. Therefore a method of determining similar flow conditions for the different rudder sections is presented. The following work identifies with three different design stages the opportunities of modern rudder design.
