Abstract	In order to provide an insight into the manoeuvring of high speed crafts, an experimental study was undertaken at the towing tank of Delft University of Technology, using a rescue vessel of the Royal Netherlands Sea Rescue Institution (KNRM). One of the primary objectives of this work is to validate a 3D time domain panel method in the manoeuvring loads calculation in calm water using the results of the experiments. The mathematical model was successfully implemented for the prediction of high speed craft vertical motions in waves. The application of this panel code to manoeuvrability problems is still in development and has to be further analysed and validated. This paper focuses on the determination of the heel and drift hydrodynamic induced hydrodynamic loads. During the experimental campaign, the heel-sway, heel-yaw coupled linear coefficients (Yφ, Nφ) and hydrodynamic heel moment (Kφ) were obtained using static heeled model measurements over a range of speeds. Then the side force, yaw and roll moment linear coefficients due to drift (Yv, Nv, Kv) were measured using static pure drift measurements. The prediction of the hydrodynamic loads in the horizontal and transverse plane for high speed marine vehicles is fundamental. The estimation of these manoeuvring loads in calm water is the first step for future applications of the mathematical model to complex dynamic problems which are dominated by the manoeuvrability characteristics of high speed craft.
