The protective device that was made with the elastic resin is excellent in restoration. Therefore when the collision ship is removed, the form almost returns to an original form. Authors are performing the research that checks the characteristic of the protective device by the model experiment and numerical analysis. In this research urethane foam and pelprene protective device models are used. In the present paper, the authors report the effect of the measure of the protective device and penetration direction in the case that the ship penetrated into protective device statically. The following results are obtained. (1) When ship penetrated the protective device that was made of elastic resin, reaction force-bow penetration curve shows that the reaction force increases linearly with increase of bow penetration to a certain distance. Then, reaction force rapidly increases with little increase in the penetration distance. (2) When location of the penetration approaches the end of the protective device, the slope of the reaction force-bow penetration curve becomes moderate. In this case, the slope of the curve at the same penetration distance increases with the increase of the width of the protective device, although this increase saturate to a certain value when the width/depth ratio exceeds six. (3) These results almost agree with the numerical analysis and model experiment.
