Seakeeping recording of a vessel, so called seakeeping trial, is an important issue which is performed for some vessels. The goal of this research is to develop principles of seakeeping trial of planing vessel in sea waves. For this purpose it is initiated with the principles of ship seakeeping in sea trial. The main feature of a planing vessel is dynamic trim, high slamming accelerations and impact nature of slamming acceleration. This behavior makes its seakeeping more complicated. In this study, for the first time, an attempt has been made to extract boat six motions in hydrodynamic coordinate system from measured accelerations and rate of angular motions in body coordinate system. To realize the goal, the three coordinate system and transformations are defined. An instruction for seakeeping trial of planing vessel is introduced. A set of seakeeping trial on boat is done and the results of measurement are analyzed according to above principles. Validation and conclusions are also presented.
