Astronavigation has the status of a secret science from the last millennium - interesting, demanding, completely outdated and far too strenuous. Most water sports enthusiasts only study it - if at all - in preparation for an exam, such as the German Sporthochseeschifferschein (SHS) or the British RYA Yachtmaster Ocean.In the event of a total power failure on board or interference with satellite signals, astronavigation is still regarded as THE backup for GPS & Co. But who can really switch to the navigation system of our ancestors on an ad hoc basis or even has the necessary nautical documents on board?Helmut Hoffrichter has developed a completely computerised method of determining location using the sun and a sextant, which he calls ‘postmodern astronavigation’. The revised, expanded 2025 edition of his book "Postmodern Astronavigation. Travelling with the sun" has been published.The book begins with an easy-to-understand review of the history of astronomical navigation. Hoffrichter then introduces his self-developed app ‘Circle of position navigation’ (Apple) and ‘Sun Navigation’ (Android).A sextant is used to measure the distance to the unmistakable sun. For the sake of simplicity, planets and fixed stars are left out as natural celestial bodies. After measuring the elevation angle, astronavigation traditionally begins with an extensive mathematical calculation and then a graphical approximation method. This was devised in 1875 by the French naval officer Marcq Saint-Hilaire (1832-1889) as an ‘emergency solution’ that was solely due to its time.Although mathematically exact navigation methods have been known since the mid-18th century, the calculation could not be automated without a computer. In Hoffmeister's app, the elevation angle measurements can simply be entered on a mobile device. Of course, the tablet or smartphone would have to run independently of the on-board power supply failure.The long-displaced methods of mathematicians Johannes Keppler (1571-1630) and Leonhard Euler (1707-1783) as well as the ephemeris are stored in the software, which performs the location calculation at lightning speed. After using the sextant, ‘postmodern astronavigation’ is as easy to use as the familiar satellite navigation on the chart plotter. Extensive nautical documentation is not required, nor do you have to do any calculations or drawings yourself.With ‘postmodern astronavigation’, a location can be determined more precisely with the help of the sun than with the Saint Hilaire altitude difference method. Since this does not even require a gissort, the art of earlier navigators is simplified to such an extent that a genuine, easy-to-use, practical navigation backup is now available.The chapters in detailHistory of astronavigationThe Sun Navigation appA little sextant loreAnalytical position determinationDead reckoningGreat circle calculationThe equation of timeAppendix, including an extract from the 1809 publication by Carl Friedrich Gauss (1777-1855) in which he solves the two-height problem188 pages, 70 illustrations and 15 tables, format 14.8 x 21 cm, hardback.

OT: Reading the Glass: A Captain’s View of Weather, Water, and Life on Ships.What is hidden in a cloud? How do jet streams and hurricanes form? How could Polynesian explorers sail east when the trade winds have been driving ships west for centuries, and what exactly is El Niño? After 30 years on board various ships, Elliot Rappaport shares his knowledge of the weather with us. He takes us on sailing voyages from the Mexican coast to the heart of the tropics, from the icy waters of Greenland to the Roaring Forties. Based on his experiences at sea, captain Rappaport explains phenomena such as thunderstorms, ice formation and volcanism in a gripping and vivid way and familiarises us with great-circle navigation and how radar works. Last but not least, he makes the connection to larger contexts such as climate development and thus manages to combine personal experience with science.Elliot Rappaport studied geosciences with a focus on meteorology and currently prepares cadets for a career at sea as a professor of maritime transport at the Maine Maritime Academy. Previously, he was a captain and professor of nautical science for over two decades at the SEA Education Association in Woods Hole, Massachusetts, which offers bachelor's degree programmes in marine science on board sailing ships.Translated from American English by Rudolf Mast. Born in 1958, Mast was a sailing instructor and sailmaker before studying theatre studies and philosophy in Berlin. He now works there as a theatre scholar, editor and translator.You will find a sample under ‘Downloads’.400 pages, format 15 x 22 cm, hardcover with dust jacket and ribbon marker. German edition.

The German edition of the book is being discontinued by the publisher.David Barrie (born 1953) is a butterfly researcher, chairman of various foundations, passionate sailor and great author with great enthusiasm for navigation topics.With his first book "SEXTANT - A voyage guided by the stars and the men who mapped the world's oceans" he succeeded in creating a successful mixture of adventure, science, mathematics and heroic deeds. Above all, however, the book is also a declaration of love for the sea. "Barrie ties everything together in a light, airy way, surprises with historical detail, pays tribute to the courage of the first seafarers setting out into the unknown and brings tragic fates out of the mist of the past," a review said.Barrie describes how unknown the outlines of entire continents were just 250 years ago. Orientation by the stars was considered imperfect. Only a new observation instrument gave the modern world its shape: the sextant. David Barrie tells the story of how and why it was invented, how vital it was for seafarers and what a central role it played in the history of exploration and discovery.He artfully combines the experiences of intrepid seafarers such as James Cook, La Pérouse and Joshua Slocum with memories of his own Atlantic crossing, which he undertook as a young man.352 pages, 12.2 x 18 cm, paperback.

Roger Barnes believes that small boats are the perfect way to access remote, beautiful places.The Brit, who was featured in the 01/2024 issue of "Yacht Classic" magazine, among others, has been sailing for years with a minimum of equipment in an open dinghy, even in such challenging waters as Brittany. His aim is to integrate sailing into everyday life without making a fuss about it, because "one of the surest routes to satisfaction in life is a small boat, a favourable wind and a new coast to explore".The book, which is now available in a second, revised edition, has long been regarded as the standard work on cruising in a simple dinghy. The information and advice are interwoven with wonderfully vivid stories about the author's adventures on the water. They range from idyllic weeks on remote rivers and along the coast to hair-raising journeys to remote islands.For this new edition, an account of the author's first capsize, new material on electronics and clothing, and more information on boat designs have been added.Topics covered in the guide are: the search for a good boatequipment for day tripsboat technique under engine and rudderMooring and anchoringPreparing for open waternavigation on open seasmaintaining a dinghycomfort and safetyHere you will learn that dinghy sailing is a wonderful way to experience nature and new coastlines at close quarters and at low cost. Sailing where bigger boats can't go and sleeping under canvas on board or ashore - it's boating stripped down to the essentials, and all the better for it. 272 pages, with inspiring colour photos and helpful illustrations throughout, 17x24 cm, paperback, Adlard Coles Nautical London.
