Abstract

This study examines the application to hydrodynamic design of shop hull forms of new optimisation techniques and in particular the genetic algorithm, in conjunction with rapid and robust first-principles hydrodynamic analysis. Emphasis is placed on the choice of the optimisation technique, the modelling of the hull-form geometry, and the selection of the analysis methods; previous work is reviewed, and alternative options are evaluated. The application of the approach to practical design is illustrated through a case study examining the hydrodynamic design of a large fast catamaran ferry.
