For over 50 years Heavy Weather Sailing has been regarded as the ultimate international authority on surviving storms at sea aboard sailing and motor vessels. In this book, former Commodore of the Ocean Cruising Club Martin Thomas brings together a wealth of expert advice from many of the great sailors of the present, including fresh accounts of yachts overtaken by extreme weather, from Ewan Southby-Tailyour, Alex Whitworth and Dag Pike to Larry and Lin Pardey, Matt Sheahan and Andrew Claughton. The expert advice section has been updated in line with current thinking, with major new additions tackling preventing or coping with lightning strikes, navigating in heavy weather with both paper and electronic charts, the choice and use of tenders in severe weather, and special problems faced by the new generation of foiled cruising boats. For the first time the book also covers the unique challenges presented by weather in high latitudes, with more yachts crossing the Drake Passage and attempting the North West Passage. These revisions ensure that Heavy Weather Sailing is as relevant, useful and instructive for today's sailor venturing offshore as it ever was. This is the definitive book for crews of any size contemplating voyages out of sight of land anywhere in the world, whether racing or cruising. It gives a clear message regarding the preparations required, and the tactics to consider when it comes on to blow.

Celestial navigation is an essential tool for those who do not wish to be caught short when modern technology fails. The basic process is simple - take a sight with a sextant, establish a secondary reference or benchmark sight, compare the two sights and plot the result of the comparison on a chart. Schlereth demonstrates how to take sight by the sun, moon, stars and planets, discussing the advantages of each method. The reader is taken through several examples and situational illustrations.

You might think stress-free navigation sounds like an impossible paradox. But it need not be. All boaters, whether under sail or under power, need to be able to navigate safely on the water - both to keep themselves and their crew out of trouble and to avoid endangering others. Yet navigation has often been presented almost as a black art - complicated, full of tricky maths, and with alien concepts to get your head around. Step in `Mr Stress-Free': having in his previous books presented techniques for sailing and motorboating in an accessible, manageable fashion, Duncan Wells now turns his attention to navigation. He makes concepts easy to understand and the practice of navigation perfectly achievable for all - with minimum stress. The book covers the basic introductory elements clearly and simply for novices, and progresses through more advanced techniques for experienced navigators, so that there is something for everyone, whatever their skill level. Diagrams, quick-reference tables and flowcharts, explanatory step-by-step photographs, box features, top tips and QR codes - giving access to explanatory videos - are all features that have been much appreciated by readers of Duncan's other top-selling titles.

Core Principles of Maritime Navigation introduces the main navigation concepts required by trainees and professionals involved in maritime operations. The book covers a wide range of subjects from wind, waves and depths to navigational marks and buoys, navigational techniques and equipment, passage planning, duties of the Officer of the Watch, berthing and anchorage. It is not intended to be a technical publication; rather, it aims to introduce core ideas and concepts in an accessible way for general readers, university students, cadets and for the continuous professional development of experienced seafarers.

Spherical trigonometry was at the heart of astronomy and ocean-going navigation for two millennia. The discipline was a mainstay of mathematics education for centuries, and it was a standard subject in high schools until the 1950s. Today, however, it is rarely taught. "Heavenly Mathematics" traces the rich history of this forgotten art, revealing how the cultures of classical Greece, medieval Islam, and the modern West used spherical trigonometry to chart the heavens and the Earth. 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 for its elegant proofs and often surprising conclusions.

"Heavenly Mathematics" is illustrated throughout with stunning historical images and informative drawings and diagrams that have been used to teach the subject in the past. This unique compendium also features easy-to-use appendixes as well as exercises at the end of each chapter that originally appeared in textbooks from the eighteenth to the early twentieth centuries.

Watch Officer's Guide, 16th Edition, is a handbook for all deck and combat information center watch officers of the U.S. Navy and U.S. Coast Guard afloat, in the air, under the sea, and ashore. Originally written more than one hundred years ago, and last revised in 2007, the book provides officers with guidance on the watch in general, communications, shiphandling, standard commands, safety, honors and ceremonies, engineering, and rules of the road - essential elements for success in standing any watch. It offers, in a single volume, a great deal of important information for aspiring officers seeking qualification, ensuring that they have the requisite knowledge and appreciation of the importance of what they are doing. For the more experienced watch officer, this 16th edition continues a long-standing tradition by providing a compendium of information handy for review and for the actual standing of a watch. The lessons and themes are shaped and geared towards the afloat watchstander; though they also provide a foundation for success in other areas of both military and personal life.

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."

Imray Laurie Norie & Wilson Ltd was formed in 1904 when three private chart publishing firms amalgamated. Each of these London companies had a long history going back to the mid-18th century. James Imray and Son published an extensive list of charts and pilot books. RH Laurie and Sons was associated with charts published for the East India Company. Norie and Wilson, founded by JW Norie, whose Nautical Tables are still supplied to navigators across the world, produced charts and books on navigation and sold nautical instruments.Until 1939 we were based in the City of London, where long serving cartographers produced charts from copper plate engravings which were supplied to mariners throughout the World. For over a century Blueback Charts were the first choice of many shipping companies. Now based in St Ives in Cambridgeshire, Imray charts are produced digitally for printed and electronic editions by our drawing office team. Our catalogue of yachting charts is regarded by the sailing community as the most comprehensive available. Our paper charts are complemented by a growing list of electronic publications and high quality pilot books by leading authors.
