Practical evaluation of resistance of high-speed catamaran hull forms—Part II

Abstract

This study attempts to extend the analysis of several resistance prediction procedures based on experimental work carried out by researchers and, subsequently, wave resistance estimation as illustrated in Part I of this study by Sahoo et al. (2007). All the methods used have been analysed and compared with results obtained from towing tank tests, CFD analysis by use of SHIPFLOW and a computational analysis is software package CATRES, whose operation is based around thin ship theory. The results obtained from each of the resistance prediction methods have been investigated, and the limitations and areas of effectiveness for each of the resistance methods have been determined in relation to the vessels tested. Throughout this study,the primary objective of validating the resistance equations developed in Part I of this study has been achieved. The level to which the resistance prediction tool can be utilized during the designing of high-speed catamarans was further determined through the analysis of the results.
