Abstract : SWATH ship model manoeuvring experiments were performed to investigate the effects of rudder configuration on turning performance and to provide free-running model data to test the accuracy of numerical simulations. Both aft of strut and aft of propeller rudders were tested. The model results indicated that the turning performance of the two types of rudders is similar at low Froude numbers, whereas the aft of propeller rudders offer superior performance at Froude numbers greater than 0.35. Correlation studies indicate broad agreement between the experiments and manoeuvring performance significantly. (Author)
