THIS EBOOK EDITION IS DESIGNED TO BE EXPERIENCED ON COLOUR DEVICES The practical guide to celestial navigation - know what to do step by step, understand why you're doing it, and be confident that you can put it into practice when on board. Did you know that a person standing on the equator is effectively travelling at 900mph? And did you know that you can use this information to work out where you are in the world, to an accuracy of about 3 or 4 miles? No GPS, no computers. Just a sextant, some tables from an Almanac and the knowledge in this book. It's the only back up if the GPS goes down, so it's a matter of safety. If you want to qualify as a commercial skipper/superyacht captain you need to know how to carry out celestial navigation. And if you want to pass the RYA Ocean YachtmasterTM exam, you need to know it too. It's a major stumbling block for many sailors wanting or needing to take their next qualifications, and the other books on the market are complex and often assume some prior understanding. This book fulfils the need for a clear explanation of celestial navigation, illustrated with colour diagrams and including unique checklist sheets to enable you to repeat all those calculations you learned back at home, when you're on deck. Without overwhelming the reader with a load of theory from the off, the author breaks down what you need to do, step by step, explaining why at every point – giving the information context, and making it more interesting and memorable. He has trained students in this subject for years, and here he's able to use his experiences of what works, and what are the common pitfalls – he even includes a troubleshooting chapter near the end, going through errors commonly made, and how to spot them. The objective is that readers will finish the book not only knowing what to do, but really understanding why, and being able to make sense of it all again later (rather than just getting through and exam and finding themselves at a loss when on deck). The author also includes time-tested 'proformas' – quick reference sheets that sailors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most sailors experience when they suddenly need to put their theoretical knowledge to the test in the real world.

Simple Celestial is an instructional manual on the art of celestial navigation. The manual is clear, succinct and thorough in presenting in a simple style the process of observing the Sun, Moon, planets and stars used in celestial navigation in order to derive a position fix any where in the world. The process of celestial navigation as presented in the manual uses an assumed position to derive an intercept that is the basis for a line of position from the heavenly body. Additionally, the manual explains the alternate method of observing the Sun at local apparent noon for a position fix. Using either method and with the appropriate supporting tools, the student will find the manual an excellent guide in completing the sight reduction form to arrive at a solution. The manual deliberately relegates theory to a small chapter in the back, concentrating rather on the practical aspects of celestial navigation.
A poignant, uplifting, heartbreaking love story from the beloved bestselling, Pulitzer Prize–winning author: "To read a novel by Anne Tyler is to fall in love" (PEOPLE). Thirty-eight-year-old Jeremy Pauling has never left home. He lives on the top floor of a Baltimore row house where he creates collages of little people snipped from wrapping paper. His elderly mother putters in the rooms below, until her death. And it is then that Jeremy is forced to take in Mary Tell and her child as boarders. Mary is unaware of how much courage it takes Jeremy to look her in the eye. For Jeremy, like one of his paper creations, is fragile and easily torn—especially when he's falling in love....
Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.
A guide for the amateur yachtsman that examines navigational problems and procedures as well as recent advances in piloting and plotting
To the uninitiated, celestial navigation appears to be a somewhat frightening exercise in mathematics. In fact, the maximum mathematics involved in the new sight reduction systems is the addition of three lines of figures. Similarly, the apparent complexities of the solar and stellar systems take on a less frightening appearance when related to the lighthouses and similar earthly objects used for coastal navigation. Throughout this book, the author uses such a comparison between earthly and heavenly objects in explaining the close relationship between coastal and celestial navigation. In doing so, he reduces a complex subject to a simple and interesting one that can be absorbed by even the most non-mathematically minded. The book concentrates for much of its length on the plotting of the boat's position by sun, planets, and stars when out of sight of land. It also deals with related navigational routines such as checking the compass by using heavenly objects, taking radio time signals, and adjusting the sextant for day-to-day corrections. This is celestial navigation in its simplest form, presented in a way which even the most amateur navigator can understand and absorb.
A radical manifesto about doing what you love Andy Merrifield offers a passionate tribute to the revolutionary spirit of the amateur—a figure who thinks outside the box, takes risks, dreams the impossible dream, seeks independence, and carves out a new world. Merrifield celebrates such square pegs as Charles Baudelaire, Fyodor Dostoevsky, Edward Said, Guy Debord, Hannah Arendt, and Jane Jacobs, each of whom shows us a path of unconventional wisdom and freedom. The Amateur advocates urgently for the liberated life, one that creates the space to question authority.
The essential reference tool for reading maps, published by the Coast Guard, is now available to boaters in an attractive, colorful edition that includes important supplementary information about navigation. A must-have for all mariners, the first half of the manual reproduces the U.S. Coast Guard book, with coverage of basic chart concepts, the anatomy of a chart, how to read a chart, symbols and abbreviations associated with National Ocean Service and Defense Mapping Agency charts, and the chart numbering system. In addition, for extra value, the USCG version has been expanded to include navigation tips and techniques from Chapman Piloting and Seamanship, 64th edition, including details on positioning procedures, dead reckoning, and river piloting.
*Shortlisted for the Baillie Gifford Prize for Nonfiction *Shortlisted for the Lambda Literary Award *Shortlisted for the Wellcome Book Prize One of The Times UK’s Best Memoirs of 2018, BuzzFeed’s Best Nonfiction of 2018, Autostraddle’s Best LGBT Books of 2018, and 52 Insight’s Favorite Nonfiction Books of 2018 A “no-holds-barred examination of masculinity” (BuzzFeed) and violence from award-winning author Thomas Page McBee. In this “refreshing and radical” (The Guardian) narrative, Thomas McBee, a trans man, sets out to uncover what makes a man—and what being a “good” man even means—through his experience training for and fighting in a charity boxing match at Madison Square Garden. A self-described “amateur” at masculinity, McBee embarks on a wide-ranging exploration of gender in society, examining sexism, toxic masculinity, and privilege. As he questions the limitations of gender roles and the roots of masculine aggression, he finds intimacy, hope, and even love in the experience of boxing and in his role as a man in the world. Despite personal history and cultural expectations, “Amateur is a reminder that the individual can still come forward and fight” (The A.V. Club). “Sharp and precise, open and honest,” (Women’s Review of Books), McBee’s writing asks questions “relevant to all people, trans or not” (New York Newsday). Through interviews with experts in neuroscience, sociology, and critical race theory, he constructs a deft and thoughtful examination of the role of men in contemporary society. Amateur is a graceful and uncompromising look at gender by a fearless, fiercely honest writer.
