Wind Vane Self Steering

In Crime is Not the Problem, Franklin Zimring and Gordon Hawkins revolutionize the way we think about crime and violence--by forcing us to distinguish between crime and violence. The authors reveal that compared to other industrialized nations, in most categories of nonviolent crime, American crime rates are comparable--even lower, in some cases. Only when it comes to lethal violence does the United States outpace other Western nations, with homicide rates many, many times greater. London and New York City have nearly the same number of robberies and burglaries each year, but robbers and burglars kill 54 victims in New York for every victim death in London. Why are the risks so much greater that victims will be killed or maimed in the United States? And what can be done to bring the death rate from American violence down to tolerable levels? The authors show how the impact of television and movie violence on rates of homicide is wildly overrated, but emphasize the paramount importance of guns. By making the crucial distinction between lethal violence and crime in general, the authors clear the ground for a targeted, far more effective response to the real crisis in American society. Crime is Not the Problem will reshape the debate about crime control in the United States.

If you are thinking of fitting an autopilot or windvane steering system to your boat but are baffled as to which is the most suitable, then this is the book for you. Peter Forthmann, a long-term expert on this subject, explains the difference between tiller, wheel and inboard autopilots, as well as the 12 windvane steering options available, and considers their suitability for various types of boat and sea conditions. Which self-steering systems are more suitable for cruising and which for racing? What are their limitations in terms of sea conditions and power consumption? What is yaw damping? Why are windvane steering systems unsuitable for ULDBs? How do you steer a catamaran without running into power consumption problems? Why is good sail trim so important for good self-steering? What self-steering provisions should you make when building a boat? Is DIY windvane gear construction still a feasible option? All these questions and many more are answered in this very comprehensive book, which concludes with a comparison of all the alternatives available and a list of manufacturers of practically every self-steering system made anywhere in the world. Peter Christian Forthmann has a unique knowledge of self-steering. Born in 1947, he learned to sail as soon as he learned to walk, growing up by the water in Hamburg. An engineer and a highly practical man, Peter Forthmann's creative contribution to the evolution of windvane steering systems is virtually unparalleled. lt is thanks in no small part to him that these systems are still thriving in the age of bits and bytes.

Here is the definitive manual for choosing, purchasing, installing, maintaining, repairing, using, and even building a windvane self-steerer, that amazing device that relieves longdistance sailors from the the helm while using not one amp of precious electrical power. This user-friendly guide includes: How vane gears work A clear discussion of how to match vane design with boat Invaluable instructions for how to sail with a windvane-- settings, sail trim, and more A detailed look at nine commercial models, plus plans and instructions for readers to build their own

This encyclopaedic volume synthesises 25 years of research and development of this unique rig as adapted to western craft. It is a work which has been welcomed by the growing number of yachtsmen and designers throughout the world who already enjoy the benefits of junk rig or who wish to do so. Now in paperback for the first time, Practical Junk Rig examines the design and aerodynamic theory behind junk rigs and discusses how best to sail them. It outlines the rig in detail, the principles that underlie it, considers possible alternative shapes and arrangements and analyses performance, all assisted by a wealth of detailed line illustrations. 'There is no better or more compehensive work on the subject available... it should be considered THE handbook on junk rigs for anyone interested in the subject' Sailing 'I cannot recommend this book too highly' Classic Boat
