Abstract

Wave resistance prediction of a catamaran by linearised theory M. Insel," A.F. Molland& & J.F. Wellicome* ^Faculty of Naval Architecture and Ocean Engineering, Istanbul Technical University, Turkey ^Department of Ship Science, University of Southampton, Highfield, Southampton, SO 17 1BJ, Hampshire, UK ABSTRACT The far field wave system and far field wave coefficients (Eggers coefficients) of a Kelvin source are presented using linearised theory including the effects of a canal depth and width. The wave resistance due to the distribution of such sources is derived using a far field wave energy approach. The trim and sinkage effects of the hull have been included by supplying the dynamic hull surface in the calculation scheme. The effect of transom stem has also been investigated by alternative methods. The developed code has been tested on a mathematically defined hull form and a series of high speed transom stern hull forms. Catamarans with separation r
