The service speed of small fishing boats have grown faster recently. Nowadays, there are some fishing boats runnnig over 25 knots (F_n>1.0). To survey the resistance and running trim of these small high speed crafts, the towing tank tests are carried out. This paper has investigate the techniques of the towing test for small ship models in free towing with high speed and the mutual relations of the test results between free and fixed towing motions of heaving and pitching. As the results, one of the conclusions of this paper is that the change of the displacement measured by the free towing test is equal to the lift force measured by the fixed towing test. This conclusion was derived from the physical simulations using free towing models loaded counter weights of the lift force measured by the fixed towing tests.
