An apparatus is newly deviced for measuring resistance, trim moment and rise of the center of gravity of a high-speed boat model with trim fixed. The experiments using the dynamometer are conducted in the circulating water channel and the results are compared with the data of the resistance test with trim free. It is revealed that resistance, trim angle and rise of the center of gravity of the freely towed model can be analyzed from trim-fixed test measurments, and that the effects of variation of initial trims, tow angles and heights of towing point in the trim-free test can be easily estimated. A rational method is proposed for predicting using trim-fixed test results to obtain full-scale performances of boat. The results analyzed are also available for comparing with theoretical methods and for development of boat forms.
