Preliminary design of an ORC GP33 racing yacht.

The aim of the dissertation is to outline the preliminary design of an ORC GP33 class racing yacht. \nThe author is particularly experienced in one-design keelboat and fleet racing. This design aims to produce a sensible, easily built and competitive GP33 class racing \nyacht. \nThe preliminary design was driven almost exclusively by the initial weight estimate, influencing all aspects of the design spiral. Wind analysis was carried out on the \nproposed racing region and the yacht was refined for sailing in these conditions. \nWhilst stability and reducing wetted surface area were key factors in optimising the boat during the iterations of the design process, from its inception the boat was to be light weight and aimed at being as fast as possible for the assumed wind conditions. \nVelocity prediction was made extensive use of, for this project, to ascertain the optimal hull parameters, as well as comparing performance to an already built and proven GP33. \nThis project proposes an easily built, fast and relatively cheap entry in to Grand Prix \nfleet racing.
