An application of optimization methods to the design of hulls with the goal of improving seakeeping is described. The seakeeping calculation technique as well as the means of generating the hull form descriptions from given sets of coefficients are outlined. A short discussion explains the selection of a critical wave height as a measure of seakeeping. Examples are given to show the influence of the structural and stability constraints on the hull forms generated. The variation of seakeeping with the hull form parameters is shown. Results are presented for optimizations at 10, 20, and 30 knots. It is concluded that optimization methods can be used in the early stages of design to develop hull forms with superior seakeeping. It calculated ship motions for 20 normalized frigate/destroyer hulls and used the significant amplitudes of 8 motion-related quantities to create a ranking number.
