Abstract

In recent years, high speed vessel received additional attention and being developed intentionally for catamaran boat race, passenger vessel, military vessel and recreational purposes. Most of hull forms used in these high speed boat types is multi-hull. Whilst the twin hull type vessel is the most popular among the multi-hulls because of their inherent features such as large deck area, better stability, lower wave-making resistance at high speeds and better safety. Since the propulsive power of any marine vehicle depends mainly on its resistance characteristics, it is required to predict the resistance of the vessel either in theoretically, experimentally and numerical study. In the present study, an attempt has been made to carry out both experimental and numerical investigations on the resistance characteristics as well as the comparison of an existing twin hull without tunnel used in developed of human powered hydrofoil. This study is expected to minimize the variation of resistance in range of 10% or les between both methods.
