Abstract : This report summarizes rotating arm model tests performed on a small and large-scale MARINER model, and on a systematic series of 14 small models based on variations of the MARINER hull form. Forces and moments on all the fully fixed models were recorded. In the large-scale MARINER tests, data on rudder inflow velocities, and the effect of the rudder and propeller on hull forces and moment were also obtained. The report then describes full-scale maneuvering trials performed on a MARINER class ship. Finally, maneuvering calculations based on modular principles are presented, and show satisfactory agreement with the trials' results. Such calculations can be performed during preliminary design to predict the effects of various hull, propeller and rudder geometries on vessel maneuverability.
