Loran and GPS notwithstanding, there will always be a place for the sextant aboard any blue-water boat, if for no other reason than the thrill and mystery of finding ones position on earth by gazing at the heavens. Here is the indispensable reference that should accompany the instrument aboard. Cmdr. Bruce Bauer, a professional navigator and master mariner with the U.S. Merchant Marine, has distilled years of hands-on experience into an eminently readable guide to buying, adjusting, using, and repairing sextants.

The Sextant Handbook is dedicated to the premise that electronic navigation devices, while too convenient to disregard, are too vulnerable to rely on exclusively. The book is designed to make beginner and expert alike conversant with this most beautiful and functional of the navigators tools. Topics include:

• Assembly and Disassembly
  
• Vital Adjustments
  
• Avoiding Problems
  
• Rough Weather Sightings
  
• Oiling and Cleaning
  
• Immersion Baths
  
• Emergency Silvering
  
• Finding and Buying Used Sextants
  
• And Much More
  

Youll also find a list of distributors, manufacturers, and dealers worldwide, a discussion of future trends, and numerous helpful hints, including sighting with eyeglasses and using a Rude starfinder. All in a thoroughly revised edition of a book acclaimed by navigation professionals.

It covers international standards and works well on courses throughout the world. Seamanship Techniques is written for serving mariners and nautical students from cadet to master level, studying for professional marine qualifications under the International Maritime Organization as per STCW requirements. Used by training establishments around the world, this best seller is the only reference to both shipboard practice and ship operations that seafarers will need.

This is an A-Z of seamanship skills for multihull sailors. There are many textbooks on the market which detail general seamanship principles. This is not one of them. Multihull Seamanship is about sea-going catamarans and trimarans and the skills needed to understand and enjoy them to their utmost. Both racing and cruising yachts are catered for, as are trailer-able multihulls. Seamanship is not a black and white skill. It is an evolution of knowledge; a building of information through experiment, thought and experience. There is no definitive word on an evolving skill. Multihull Seamanship started as Dr Gavin Le Sueur's personal index of `how-to's. It has grown through experience and others sharing their knowledge. It should be on the book shelf of every catamaran and trimaran. This book is for people who are already multihull sailors, or for those who are contemplating multihull sailing. It has served this community for over 20 years and this second edition is fully updated. It is illustrated with delightful line drawings by Nigel Allison.

The two first CEAS (Council of European Aerospace Societies) Specialist Conferences on Guidance, Navigation and Control (CEAS EuroGNC) were held in Munich, Germany in 2011 and in Delft, The Netherlands in 2013. ONERA The French Aerospace Lab, ISAE (Institut Supérieur de l’Aéronautique et de l’Espace) and ENAC (Ecole Nationale de l’Aviation Civile) accepted the challenge of jointly organizing the 3rd edition. The conference aims at promoting new advances in aerospace GNC theory and technologies for enhancing safety, survivability, efficiency, performance, autonomy and intelligence of aerospace systems. It represents a unique forum for communication and information exchange between specialists in the fields of GNC systems design and operation, including air traffic management. This book contains the forty best papers and gives an interesting snapshot of the latest advances over the following topics: l  Control theory, analysis, and design l  Novel navigation, estimation, and tracking methods l  Aircraft, spacecraft, missile and UAV guidance, navigation, and control l  Flight testing and experimental results l  Intelligent control in aerospace applications l  Aerospace robotics and unmanned/autonomous systems l  Sensor systems for guidance, navigation and control l  Guidance, navigation, and control concepts in air traffic control systems For the 3rd CEAS Specialist Conference on Guidance, Navigation and Control the International Program Committee conducted a formal review process. Each paper was reviewed in compliance with standard journal practice by at least two independent and anonymous reviewers. The papers published in this book were selected from the conference proceedings based on the results and recommendations from the reviewers.

This book acts as a manual for the ancient methods of navigating by the stars, which continue to provide the sailor or pilot with a timeless means of determining location. Despite the prevalence of GPS, a comprehensive set of formulae that can be evaluated on any inexpensive scientific calculator in the event of a catastrophic software or systems failure is a vital failsafe. It also serves as a living link to centuries of explorers from centuries past. Beginning with the basics of positional astronomy, this guide moves on to the more complex math necessary to understand the ephemerides, tables showing the future positions of the stars and planets. These astronomical almanacs were the satellite navigation of their day. The objective of this book is twofold: to provide the reader with a concise, comprehensible manual on positional astronomy as it applies to astro-navigation and to furnish the concise algorithms for finding the position of the Sun and various navigational stars at any given instant. In a world where too many mariners and aeronauts rely solely on technology and are vulnerable to solar flares, electrical issues, and the like, this knowledge can be a life-saving backup, not to mention a fascinating study in its own rights. Included is an exact mathematical way to determine your position in the air or on the sea far more quickly and accurately than by using the old celestial navigational method, without even needing to know or understand the underlying mathematics. There is even a section that teaches how to measure the azimuth of a star using an analog wrist watch so if a sextant gets damaged, locating position is still possible. This book offers mathematicians and adventurers a way to determine position when the skies go dark. The U.S. Navy has recently realized that their electronic navigation systems are vulnerable to cyberattack, and as a result has instructed the Naval Academy to begin teaching celestial navigation again.

For centuries, ships' commanders kept journals that recorded their missions. These included voyages of discovery to unknown lands, engagements in war and sea and general trade. Many of their logs, diaries and letters were lodged at The National Archives and give a vivid picture of the situations that they encountered. Entries range from Captain James Cook's notes of his discovery of the South Pacific and Australia, to logs of the great naval battles, such as Trafalgar and the Battle of the Nile. From the ships that attempted to stop piracy in the Caribbean, to the surgeons who recorded the health of the men they tended and naturalists who noted the exotic plants and animals they encountered, comes a fascinating picture of life at sea, richly illustrated with maps, drawings and facsimile documents found alongside the logs in the archives.

The ninth edition of Inland Waterways of France is the ideal guide for planning cruises in and through the most fascinating and diverse waterway network in Europe. This edition takes a new paperback format, split into three volumes. Author David Edwards-May presents a detailed overview of the waterways extending from the English Channel through Northern France, Picardy and Paris to Central France and Burgundy. This system totals 2700 kilometres of waterways that are as vibrant as ever, and include the new Seine-Nord Europe Canal, now under construction, to be completed by 2028. Recreational use is growing alongside the commercial traffic on the busier waterways, while Champagne, Burgundy and Central France have become cruising destinations in their own right. This first volume of the new edition sets out the current state of the network in 200 pages in full colour, with detailed maps of junctions and other key sites on the network, overview maps for each waterway, and route descriptions. It is a unique blend of practical information, maps, background historical notes and colour photographs.

Navigable waters cover almost three-quarters of the surface of our planet, and they have been home to centuries of seafarers who, being isolated from land for extensive periods, developed a specialized language all their own. Their language is a complex mixture of the strange and the familiar, including words taken from many English dialects, coined words, slang words, words used by mariners speaking other tongues, and words developed to identify occupations, titles, equipment, or activities. With its many intricate nuances, 'navalese' can be as esoteric and incomprehensible to the layperson as ancient Egyptian hieroglyphs - but such a specialized language is vitally important to a profession in which complex technical concepts need to be communicated briefly and accurately from seaman to seaman. This book is an alphabetical compendium of more than 9000 nautical terms taken from numerous dictionaries, glossaries and other sources of nautical terminology, including volumes on nautical customs and traditions, ghost ships, paranormal maritime events, sea serpents, and marine monsters. Many of the entries are brief and factual, but when appropriate the author has inserted anecdotal material of colorful or intrinsic interest. The volume should be a helpful reference for researchers and laymen who want to understand nautical speech and customs, but it should also be of use for professional seafarers who cannot always be familiar with the complex vocabularies of today's specialized maritime occupations, let alone those of bygone ages. There is an appendix that discusses real and speculative sea monsters, while 17 tables cover wind and wave measurement, date and time notation, phonetic alphabets, maritime signals, navigation rules, military and naval ranks and ratings, and the process of boxing the compass.

This edition of The Seamanship Examiner has been fully updated with the latest amendments to the COLREGs and is a trusted study aid for all international STCW Deck Officer candidates including Officer of the Watch, Chief Mate and Master positions, plus those working coastal and inland waters in the fishing industry such as Deck Officers.

Augustin Fresnel (1788 1827) shocked the scientific elite with his unique understanding of the physics of light. The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it. The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.

Levitt s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention."

Throughout the history of warfare at sea, navigation has been an important basic determinant of victory. Occasionally, new members of the fraternity of the sea will look upon navigation as a chore to be tolerated only as long as it takes to find someone else to assume the responsibility. In my experience, such individuals never make good naval officers. Commander Hobbs has succeeded in bringing together the information and practical skills required for that individual who would take the first step down the road toward becoming a competent marine navigator. At the outset of this book, the author stresses the necessity for safe navigation, but there is another basic tenet of sea warfare that this book serves. The best weapons system man has ever devised cannot function effectively unless it knows where it is in relation to the real world, where it is in relation to the enemy, and where the enemy is in relation to the real world. Not all defeats can be attributed to this lack of information, but no victories have been won by those who did not know where they were.

This comprehensive and authoritative guide to practical navigation draws on the author's extensive experience of leisure cruising and ocean racing. It combines detailed directions on how to navigate along coasts, in harbours, at night and in bad weather with easy-to-understand technical information about the electronic tools involved in safe navigation, including radar, GPS, AIS and chart plotters. Key basics such as charts, buoys, lights and tides are carefully explained and illustrated with diagrams and colour photographs throughout. Practical descriptions of navigation scenarios, such as fixing a position or plotting a course, are brought to life with anecdotes and precise detail. An indispensable reference guide for anyone wishing to sail or motor a boat safely in any situation.

It's easy to confuse (or forget) what particular lights, marks and shapes mean - especially under stress or in the dark - but with this handy book, help is quickly at hand. Laid out simply & clearly for quick accessibility, it enables crew, navigators, skippers and even casual day guests aboard to quickly identify the lights, marks and shapes being displayed by other ships at night as well as during the day. A ready reckoner reminder of: -Cardinal buoys and channel markers -Lights displayed by ships at night (tugs, dredgers, pilot vessels, stationary vessels, fishing boats, yachts, motorboats) and from all aspects (front, side, astern) -Daytime shapes displayed by boats (e.g. for anchoring, towing, diving, dredging) -Ships' sound signals (used in fog) -Signal flags and their navigational meanings (I am dragging my anchor; You are running into danger; I have a diver down). These lights, shapes and marks are applicable worldwide, by maritime law, which makes this international handbook a valuable and popular addition to the Reeds Handbook series.

Heavenly Mathematics traces the rich history of spherical trigonometry, revealing how the cultures of classical Greece, medieval Islam, and the modern West used this forgotten art to chart the heavens and the Earth. Once at the heart of astronomy and ocean-going navigation for two millennia, the discipline was also a mainstay of mathematics education for centuries and taught widely until the 1950s. Glen Van Brummelen explores this exquisite branch of mathematics and its role in ancient astronomy, geography, and cartography; Islamic religious rituals; celestial navigation; polyhedra; stereographic projection; and more. He conveys the sheer beauty of spherical trigonometry, providing readers with a new appreciation of its elegant proofs and often surprising conclusions. Heavenly Mathematics is illustrated throughout with stunning historical images and informative drawings and diagrams. This unique compendium also features easy-to-use appendixes as well as exercises that originally appeared in textbooks from the eighteenth to the early twentieth centuries.
