This paper proposes an alternative experimental technique for slamming experiments. The main idea of the proposed experiment is to replace the free-fall of the specimen, by accelerating the specimen using an air pressure cylinder at a very short distance from the water surface. The travel distance of the specimen was less than 10cm. The experiments have high repeatability. The maximum pressure peak was almost the same when the results from the free-fall experiment were compared with those from the air pressure cylinder experiment. The proposed experimental technique on slamming, by using an air pressure cylinder, was shown to be quite promising.
