N2 - The interaction between hulls, their position and shape and the length of the side hulls of a multihull affect the amount of wave resistance. This paper presents computation based on Michell’s theory on the various configurations of pentamaran and correlates with towing test data that involves interference flow around the component hulls. The pentamaran hull form was featuring a warped chine for the main hull recommended by Savitsky and V model for outriggers. Analysis of both transversal and divergent waves was performed to assess the magnitude of wave resistance that occurs due to the placement of the side hull to the main hull. Furthermore, investigations on far-field wave pattern, wave interference, wave resistance as well as total resistance have been conducted. Changing of the side hull on clearance strongly affects the resistance characteristics than stagger. Configuring the pentamaran so that the main hull is placed at the centreline of each of the front-side hull approximately 15°-18°could be an effective manner to reduce resistance. In general, all of the resistance components results showed that Michell’s theory agree with the test, particularly at Fn greater than 0.5, in which possible viscous factors were still influential at low speed where the theoretical prediction could not be potentially valuable.
