Seakeeping For Design: Development and Applicaion of An Inverse Analysis Design Methodology To Multihull Forms.

This paper is concerned with the provision of an automated ship design methodology capable of improving the design of catamarans at the conceptual design stage. After summarising the monohull design chart and automated design approaches, developed and reported previously, and the associated catamaran design chart approach reported more recently, a new automated catamaran seakeeping for design procedure is presented and applied. The results are discussed in some detail. Furthermore, identified conflicts arising from the use of interacting and non-interacting strip theory based hydrodynamic databases, to provide a simple fast design method, are discussed and some practical guidance given on how to use the developed procedures.
