Windvane or autopilot – it is one of the eternal questions of long-distance sailing. This practical guide brings clarity to the debate: it investigates the technologies behind all of today's common self-steering systems, explains which solutions are best suited to which type of boat with respect to size and construction, describes how to make the most of the various options on offer and examines the relative advantages and disadvantages of each. Which systems are good for racing and which for cruising? What are the limitations of each in terms of sea conditions and power consumption? Why is proper sail trim so important for good self-steering? Peter Förthmann answers these questions and more without resort to complicated diagrams and impenetrable technical speak. A comprehensive resource written from a wealth of personal experience, this book is full of clearly explained tips to help you choose the right self-steering solution and bring the best out of it in use. An overview of the market and a directory of almost all the self-steering systems available right around the world complete the picture.
