Abstract : A computer technique has been developed to select a set of fins for an arbitrary SWATH configuration, providing it with stability and favorable dynamic response characteristics. The design technique is based on an analytical stability determination and evaluation of dynamic responses for an array of fin sets which vary in aft fin to forward fin area distribution and longitudinal fin location. Presented in the fin selection technique with sample results and guidelines helpful to the user. The technique offers an efficient and economical tool for designing SWATH stabilizing fins in a technically objective manner. (Author)
