"Astro-navigation from Square One to Ocean-master" is an impressively dynamic and understandable book. It is clear and concise with a large number of excellent diagrams that admirably compliment the text, demystifying and simplifying the art of astro-navigation. The excellent glossary of terms and language used, together with the highlighting of important points make this book particularly applicable to teachers, students and those new to the subject."Captain James P. Hughes. Lecturer in Nautical Science, South Tyneside College

Derek Bowskill's lively commentary to the River Seine is both a comprehensive guide as well as source of all the essential information for navigators on the river from the sea to Paris and beyond to the start of the French inland waterways system. River Seine Cruising Guide covers the Seine estuary to Paris, the river above Paris and the Canal de l'Ourcq and L'Oise. Throughout, the narrative is illustrated with clear maps that indicate key places, and towards the end of the book there is a comprehensive directory of technical information. Bowskill's work is an excellent companion not only for the trip to Paris but also to the Mediterranean.

"Navigation puzzles, controversies, historical problems, and other ponderables demystified by an expert navigator and writer. Joe Portney is a US Naval Academy graduate and Air Force navigator who has participated in three historic flights over the North Pole. He is a past President of the Institute of Navigation and recipient of the Weems Award for continuing contributions to the art and science of navigation. He has produced a wonderful little book here, chock filled with interesting tidbits, each of which can be read in a few minutes but will stimulate your thought for many days to come. Some are very basic, others more involved, but he provides a clear explanation of each. Some refer to math computations that we might not all be familiar with, but this is not a distraction from the main points being made even in these few cases."

Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from just one landmark. The angular dip of an object (island or vessel) below the visible horizon can also be used to determine the distance to it. This booklet explains how to get the best results from plastic sextants, and presents numerical comparisons with similar data from metal sextants. Sextant piloting techniques are also reviewed as they are an ideal use of a plastic sextant.

A provocative new look at an important security topic examines terrorist threats and attacks on shipping and ports—and provides strategies for safety. Terror on the High Seas: From Piracy to Strategic Challenge is a provocative look at maritime security and the steps that must be taken if terrorist threats are to be nullified. From the Achille Lauro hijacking to the bombing of the USS Cole to attacks on shipping channels, terrorists have employed a variety of tactics, both successful and unsuccessful. These have included the smuggling of arms and plots to bomb shipyards, as well as attacks on Merchant Marine ships, maritime offices, fuel storage facilities, and Navy personnel, ships, and facilities, on shore and in port. This book constitutes the first research effort after the unprecedented attacks of September 11, 2001, to provide government, industry, and the academic and policy communities with a major resource on potential threats to the maritime environment. Assuming that past tactics, as well as a variety of other unconventional attacks, will be utilized by both domestic and international groups well into the 21st century, the book sagely outlines the response needed from government and industry to meet the coming challenges.

This book contains the definitive analysis of the navigation and achievement of the discovery of the North Pole by Robert Peary and Matthew Hensen in April of 1909. The report is the work of members of the Foundation for the Promotion of the Art of Navigation. It was commissioned by the National Geographic Society in 1989 to resolve the controversies surrounding this achievement once and for all. "I consider this the end of a historic controversy and the confirmation of due justice to a great explorer." - Gilbert M. Grosvenor, President National Geographic Society

A detailed, almost daily, record giving an accurate and authentic narrative of over two years in the life of a common sailor before the mast in the American merchant service of the early 1800s. The book is written in journal fashion in the words of an ordinary sailor on the brig "Pilgrim" on her voyage from Boston, round Cape Horn to the western coast of North America. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. Home Farm Books are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

The definitive guide to a critical, hotly debated topic

How should a sailor cope with storms at sea? Some advocate heaving-to, others running off. Some say trail a sea anchor over the bow, others a drogue astern. The stakes in the discussion couldn't be higher, or the consensus lower. Finally, preeminent sailor/author Hal Roth offers a practical strategy that can evolve and respond as storms grow stronger.

Over that past decade, the growth of GPS and other navigation systems has been staggering. More and more electrical engineers are migrating towards work in this field and require knowledge of important GNSS (global navigation satellite system) principles. That's why Artech House decided the time was right to put this classic Prentice Hall title back into print. Although technology has progressed at a remarkable pace in the decade and a half since its publication, the principles of navigation systems described in this book are immutable.In fact, the book presents the engineering basics so well that practicing engineers and students have been scouring the Internet looking for used copies. Finally, this essential resource will be readily available, providing authoritative guidance on everything from the fundamentals of terrestrial navigation, error calculations, and direction finding...to satellite orbits and geometry, satellite navigation principles, and spread spectrum. Moreover, the book provides concise descriptions of key navigation systems developed decades ago that are still widely in use - information that is extremely hard to find.

A FASCINATING INVESTIGATION OF HOW WE NAVIGATE THE PHYSICAL WORLD, "INNER NAVIGATION" IS A LIVELY, ENGAGING ACCOUNT OF SUBCONSCIOUS MAPMAKING.

Why are we so often disoriented when we come up from the subway?

Do we really walk in circles when we lose our bearings in the wilderness?

How -- and why -- do we get lost at all?

In this surprising, stimulating book, Erik Jonsson, a Swedish-born engineer who has spent a lifetime exploring navigation over every terrain, from the crowded cities of Europe to the emptiness of the desert, gives readers extraordinary new insights into the human way-finding system.

Written for the nonscientist, "Inner Navigation" explains the astonishing array of physical and psychological cues the brain uses to situate us in space and build its "cognitive maps" -- the subconscious maps it employs to organize landmarks. Humans, Jonsson explains, also possess an intuitive direction frame -- an internal compass -- that keeps these maps oriented (when it functions properly) and a dead-reckoning system that constantly updates our location on the map as we move through the world. Even the most cynical city-dweller will be amazed to learn how much of this innate sense we use every day as we travel across town or around the world.

Both a scientific and a human story, "Inner Navigation" contains a rich assortment of real-life insights and examples of the navigational challenges we all face, no matter where or how we live. It's a book that is as provocative to ponder as it is delightful to lose yourself in. Don't worry: Erik Jonsson will help you find your bearings.

The Army version "Map Reading and Land Navigation" is the simplest and most straightforward explanation of how to get around with just a compass and a map. This guide is perfect for any outdoorsman or for teaching Boy Scouts how to use a compass.

The book is an excellent guide for Marine Engineers, especially those who have just about started with a career out at sea. Lost in the confines of a never-seen-before engine room, this book brings a deep insight into the actual functioning and the ropes of maintaining machinery on a sea going vessel. Most books are written with the purpose of succeeding at the examinations for certification. This book discusses performance criteria of equipment in detail, maintenance based on those criteria with over 170 sketches, drawings and images, and troubleshooting to resolve problems faced on those rust buckets. The book emphasizes training to be a great manager, staying one step ahead of peers (and may be half a step ahead of superiors). Like they say - who needs mathematics to trace a choked filter, huh? A fun book and yet an eye-opener for those still to find their sea legs.

This is a book which will appeal equally to naval enthusiasts and ship modellers. It offers an overview of the design, development and classification of modern warship types and it studies the constructors' original models, explaining why and how they were made. The reader is shown how to research and select information on specific ships and how to find and understand plans. The book then turns to scale modelling with detailed chapters on choosing a subject, a scale, methods of construction (scratch or kit?), materials and techniques and the details of fittings and painting. The book leaves the reader with a deeper insight into the direct relationship between the full sized vessel and the realistic scale model or working model. The work presents an overview of the design, development and classification of modern warship types and offers an appreciation of the complex structures associated with real warship designs and how they can be related to those on warship models. It is illustrated by over 100 of the authors' fine quality photographs, many of which have never been published before.

Unmanned marine vehicles (UMVs) is a collective term used to describe autonomous underwater vehicles, remotely operated vehicles, semi-submersibles, and unmanned surface craft. Considerable interest has been shown in UMVs by the military, civilian and scientific communities due to their ability to undertake designated missions whilst either operating autonomously and/or on co-operation with other types of vehicle. Increasing importance is also being placed on the design and development of such vehicles as they are capable of providing cost effective solutions to a number of littoral, coastal and offshore problems. This book draws attention to the advanced technology which is evolving to meet the challenges being posed in this exciting and growing field of study.
