This paper stated the variation of the hydrodynamic resistant coefficient K of hand knitting plane model net which was set perpendicularly to the flow of water. The scale of the model net was determined after Tauti's principle for similarity law and experi nent was conducted for measuring the coefficients about two cases of the nets composed of flat knot (reef knot) and trawlers knot(sheet bent). The scale of the model nets which was used in experiment were 1/10, 1/20, 1/30, 1/40, 1/50, 1/60, 1/70, 1/80, 1/90 and full scale. The result of this experiment in circulating water tank came to the conclusion that; a. The hydrodynamic coefficient of trawler knotted net showed about 0.55 higher than the flat knotted net. b. The value of K coincided approximately with the value estimated by the formulae which H. Miyamoto, M. Nomura and Y. shimozaki calculated from experiment. c. The hydrodynamic coefficient K were not varied when the scale ratio was larger than 1/50, the value of K was increased gradually from 1/60 and suddenly increased at 1/80 and 1/90. Therefore, when we design a model net it is appropriate to restrict the scale ratio to less than 1/50, under the condition that the velocity of the full scale is 1.3 knot in this experiment.
