Two computer programs are presented for use, either singly or in sequence. The first will derive, from minimal data, a consistent set of parameters which, entered into the second, a velocity prediction program (VPP), will predict a sailing yacht's speed and course over a full range of wind strength and direction. Due to the limited input data as well as to the simple form of the VPP, approximate results must be accepted. The design program combines guidance with flexibility so that reasonably accurate and consistent dimensions, largely empirically derived, including weight and stability estimates, are quickly produced and tested, by the VPP, for performance.
