The resin fender that was made with the elastic resin has a good compression characteristic for energy absorber. We are doing the research that checks the characteristic of the resin fender by the model test and numerical analysis and used urethane foam and PEL-fender as a model. In the present paper, we report about the research result of the model test in the time that the ship that is different bow measure collided dynamically. When rearranging the results, (1) When the entrance angle of the bow becomes large, the slope of a reaction force-bow penetration curve become steep. At this time, the change rate of the slope becomes steep with the increase of the entrance angle. These characteristics agree with the result of a static test. However, reaction force bigger than a static test. (2) Absorbing efficiency and energy absorbing factor do not change by the bow measure.
