The protective device that was made with the elastic resin is excellent in restoration. Therefore, when the collision ship is removed even if the ship collides with it the form almost returns to an original form. Recently, we are doing the research that checks the characteristic of the protective device by the model experiment and numerical value analysis and use the urethane foam as a model. In the previous paper, we discussed the characteristic of the time that the ship penetrated into it statically. The bow model that we used is 1 kind and entrance angle is 35 degrees. In the present paper, we report about the research result in the time that changed the measure of the bow. The following results are obtained. (1) When the entrance angle of the bow becomes big, the slope of a reaction force-bow penetration curve becomes steep. At this time, the change rate of the slope becomes steep with the increase of the entrance angle. (2) When the curvature radius of the top becomes big, the slope of the reaction force-bow penetration curve becomes steep a little. The influence of radius curvature decreases when the entrance angle becomes big. (3) These results almost agree with the numerical value analysis and model experiment.
