This paper presents a commercially viable method of hull form variation, and optimization with respect to resistance and seakeeping characteristics. Genetic Algorithms (GAs) were utilised to perform a search in an initial population of 30 designs based on a BSRA methodical series hull form. 50 generations were created with the help of selection, crossover and mutation operators. The genetic algorithm code was written as an MS-Excel Macro. It interfaced with the Maxsurf suite of software to modify designs, create new generations and evaluate each design's performance in terms of Vertical Bow Acceleration (VBA), Relative Bow Motion (RBM) and hull form resistance. The hull parameters varied were the B/T ratio (Beam/Draft), Length, and position of Longitudinal Centre of Buoyancy (LCB).
