Fore-Body Trimaran and Experimental Study of Its Resistance and Motion Characteristics

The resistance and motion characteristics of trimaran hull form have been studied by experimental method.The model experiment consists of two parts: the resistance experiment on calm water and the motion experiment in regular waves.According to the experimental data,it can be found that the longitudinal arrangement of the side-hulls plays an important role in trimaran resistance and motion characteristics.For high speed range,the trimaran resistance and motion performance could be significantly improved by placing the side-hulls before the mid-ship of the main hull.Based on the experimental results,a new ship type known as fore-body trimaran i s presented.
