This book investigates the technical principles and practical adjustments required to optimize the performance of a racing yacht across various conditions. Authors Mike Fletcher and Bob Ross leverage their extensive experience in competitive sailing to provide a comprehensive framework for rig tuning and equipment management. The text translates complex aerodynamic and hydrodynamic concepts into actionable adjustments, ensuring that sailors can maximize the speed and responsiveness of their vessels regardless of the specific class or size.

The subject matter points to a highly technical, specialist manual intended for competitive sailors seeking to refine their performance through precise mechanical adjustments. The inclusion of extensive visual aids suggests a focus on practical application rather than theoretical discourse, positioning the work as a functional reference for the racing community.
