Издание на английском языке. В русскоязычном переводе книга называется Настройка парусов и такелажа.

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 this all seems a little daunting as it is not necessary to have an in-depth understanding of this subject in order to get good results.
Aerodynamics is a difficult scientific field of which few yachtsmen have in-depth knowledge. "Experts" abound and try to explain sail and rig workings 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 link to what you are actually doing out at sea.
In this book I have tried to distil those theories and rules of thumb which are commonly agreed upon in the sailing community. Having said this, I feel strongly that careful observation and common sense are the best shipmates to have onboard. What distinguishes this book from the majority is the short, focused text with illustrations. My aim has been to make it easy to find, understand and remember the information you are looking for.
This book has been inspired above all by North Sail's Fast Course™, but also by many other books on sail and rig trimming, too numerous to list. No doubt it can be improved and I will be most grateful to anyone who should be motivated to send me corrections or comments.
