The design of a vessel is premised on its operation needs. In the specific case of sailing yachts, there is a clear distinction between cruising or racing yachts. This distinction has a direct influence on its hull geometry, which may be difficult to define in its initial phases of the project. The wide range of possibilities for hull lines generates uncertainties of the best geometry to achieve its main purpose. Few development tools have as an entry parameter the purpose of the sailing yachts, whether be cruise or racing one. Thus, this study works on the development of a tool to generate the offset table of sailing yachts, having as entry information the main dimensions and its operation purpose.
