This book will teach you how to trim your sails and rig in the best possible way. Aerodynamics constitutes the theoretical background for most books on sailing, but the reader should not be discouraged if all this seems a little daunting as it is quite unnecessary to have a profound understanding of this subject in order to achieve good results.
Aerodynamics is a difficult scientific field of which few yachtsmen have a deep knowledge. "Experts" abound and try to explain sail and rig functions using the latest fashionable theories. Some of these theories are imprecise and do not stand the test of time. Frequently they apply to particular cases but cannot be applied in general. Lessons learned from experience and observation are usually more valuable than the blind application of some advanced scientific theory that may have a poor relationship to what you are actually doing out at sea. In this book I have tried to distil those theories and rales of thumb which are commonly agreed upon in the sailing community. Having said this, I strongly feel that careful observation and common sense are the best shipmates to have on board. What distinguishes this book from the majority is the short, concentrated text with adjacent corresponding illustrations. My aim has been to make it easy to find, understand and remember the information you are seeking. This book has been inspired above all by North Sail's Fast Course™, but also by many other books on sail and rig himming, too numerous to list. No doubt it can be improved and I will be most grateful to anyone who should be moved to send me correction or comment.
