Book Description
This book has been used for 30 years, updated periodically as needed. More than 20,000 students have successfully learned ocean navigation from these materials and gone on to cross oceans or circumnavigate the globe. This book covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required. The only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it book, which also includes clear explanations of how it works and how to do it well. Plus this book includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, and more. At the end of this book, you will be ready for ocean navigation. The book includes: text, practice problems, tables selections, detailed glossary, and full solutions. Printable work forms, plotting sheets, and other resources are available at no charge from www.starpath.com/celnavbook. Preface to the Second Edition: We are pleased to say that after ten more years of using this text we do not find reason to change the basic approach and methods of the teaching. We still use most of the same examples, which are now quite old, but that is the beauty of celestial navigation. It has not changed, so we do not benefit in any way from making all new examples, which would bring with them more chance of error in a book of many numbers. We have, however, notably improved and expanded the book. Each section has been updated and reformatted for a clearer presentation, often in response to student questions over the years. New graphics have been added and older ones all updated. There is much new content in the text, especially in the In-Depth chapter, including more detailed discussion of the sailings and more background on the principles. New sections were added on general ocean navigation and optimizing the fixes. We have also updated the electronic navigation section, as most ocean navigators will also be using other tools besides celestial.

Book Description
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....

Book Description
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.

Book Description
The 12th edition of this bestselling book is proof of the success of Mary Blewitt's concise and clear style in explaining a particularly difficult skill, and it has been the bible for many generations of ocean navigators. Since this book was first published, the huge advances in electronic navigation have transported most offshore navigators to a world of press-button convenience. However, there is still a vital need for traditional skills when things go wrong: batteries can fail, aerials go overboard, and electronics have been known to get wet. A bestseller for over 50 years, Celestial Navigation for Yachtsmen is a model of simplicity and clarity. The worked examples require only straightforward addition and subtraction, which explains why this book has truly earned its reputation for admirable conciseness and for making a tricky subject easy to understand. 'The "bible" of navigation for generations of yachtsmen... worth its weight in gold' Sailing

Book Description
Praised by The Practical Sailor as "a first-class piece of work," Susan P. Howell's Practical Celestial Navigation was developed for Mystic Seaport's navigation courses. This third edition, originally published by the Seaport's Planetarium, retains the step-by-step format of the original, along with an abundance of diagrams and practice problems. Practical Celestial Navigation is recommended as a self-instruction text for beginners or for old celestial hands getting back in practice.

Book Description
"Any kind of boating can be fun," the author points out, "racing around the marks, or coastwise cruising where there is almost always at hand visual reference ashore from which bearings can be taken for locating one's position and thus finding one's way home. Severing these ties with land, however, offers a new kind of fun, a new kind of freedom, a freedom from dependence on land." Here is a basic beginner's book, introducing the amateur to the tools, the vocabulary, and the techniques of celestial navigation. Among the recommended tools are the H. O. 249 tables, the most widely used among amateur navigators at sea because of their simplicity. The ability to determine one's position at sea both liberates the sailor from the land and enables him to find his way to his destination. If you can read, add and subtract, understand angles, and use a protractor, you can learn to navigate in your armchair or at sea from Celestial Navigation by H. O. 249.

Book Description
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.
