Research has been carried out to provide improved engineering methods for handicapping ocean racing yachts. A velocity prediction program (VPP) has been developed to simulate the sailing performance of a given yacht, in terms of parameters which represent its hydrodynamic and aerodynamic characteristics. Race results have been analysed to validate the VPP, and also to optimize time allowance formulae. An electro-mechanical hull measuring device has been developed to facilitate the measurement of hull offsets in a complete and precise manner. These results of the Pratt Project already have found application, especially in the USYRU Measurement Handicapping System (MHS).
