CELESTIAL NAVIGATION FOR YACHTSMEN. 13th Edition
By Mary Blewitt. Paperback, 84 grams, 138m x 212mm, 78 pages, black & white illustrations and tables, published 2017.
The 13th Edition of this bestselling textbook 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 making a tricky subject easy to understand.
This edition has been thoroughly revised by Andy Du Port to ensure that it remains entirely relevant to offshore sailors today.

Revised text and new photographs
Access to online video tutorials

Click for details of the Celestial Worksheets
The worksheet pads are designed to be used as an adjunct to class-room teaching; each one contains a copy of table 5 (corrections to Ho for minutes of declination), and a copy of the altitude correction tables for the sun and stars, including dip. There are 15 sight-sets, each of which contains worksheets for 2 sun sights, one meridian passage, and a plotting sheet. The plotting sheet is scaled at 100 mm to 40 miles and contains a compass rose and a departure to difference in longitude graph, similar in orientation to the standard US Navy plotting sheet. Each page has a panel for certifying the contents as unaided work; this would satisfy the need for practical sights required for certificates by some administrations.

By Dag Pike. Pbk, 140mm x 210mm, 104 pages, monochrome drawings. 0.15 kg. Published 2003
Despite the accuracy and ease of use of electronic navigation systems, every navigator should be able to use a sextant.

Dag Pike is a seaman and navigator of great experience, and is best known as the navigator of Virgin Atlantic Challenger, on its successful record attempt.

THE SEXTANT HANDBOOK Adustment, Repair, Use and History
By Bruce Bauer. Pbk, 150mm x 235mm, 189 pages, monochrome drawings and photographs.
" The wealth of useful material is prodigious and by the time one has reached the back cover, the sextant is an old friend. Just as important, Cdr. Bauer deals comprehensively with maintenance and sevice and his advice on how to select and assess a second-hand sextant is truly worthwhile. Refreshingly, he writes in a friendly manner-almost as though he is chatting to a group of students. A thoroughly enjoyable book". (Peter Milne Technical Editor, Yachting World) Then the last chapter is on "Sextants of Tomorrow" very interesting.

CELESTIAL NAVIGATION EXERCISES
By Dominique F Prinet. Softcover. 0.49 kgs, 218mm X 280mm, 192 pages plus tables and line drawings.

Students taking a course from an instructor who follows the slide [presentation will normally have the associated course book Celestial Navigation using the Sight reduction Tables Pub. No. 249 In order to facilitate the download process, the free version of the exercise manual (available for download at CelestialNavigationBook.com, includes neither the almanac nor the Sight reduction tables required for calculations because these tables are identical to the ones in the course book.

NORIE'S NAUTICAL TABLES.
1.72 kgs, Hardback, 210mm x 305mm, 576 pages. Revised Edition 2018
Since J W Norie published the first edition of this famous set of mathematical tables (in 1803), the book has become – and remained - a bestseller. Despite developments in electronic navigation it remains an essential requirement for anyone learning and practising astro-navigation.
Since the commissioning of the Global Positioning System (GPS), its proven accuracy and reliability in all weather conditions have resulted in confidence and almost unquestioning dependence on its ability to provide a vessel’s position, course and speed. Because of this, some seafarers feel that the traditional navigational methods are obsolete. However, the marine environment of heavy vibration, stormy seas, salt-laden spray and wide temperature variations can easily damage electronic equipment. No prudent seafarer would proceed on an ocean passage without a reliable navigational back-up.
Because of the difficulties which may be experienced if GPS should be unavailable, the book gives an explanation in the form of a detailed step-by-step description, by means of worked examples, of the different methods of calculating the ship’s position using the tables and/or a pocket calculator.
Since the last update in 2007, the editor, George Blance, has made many changes- new tables have been included and obsolete ones deleted to conform with changing techniques of navigation, with the aim of improving the accuracy of the calculated position and reducing the tedium of the calculation. The section: Seaports of the World has again been extensively updated and restructured with several hundred additional ports. The ports are listed geographically and also indexed alphabetically to aid identification.

SIGHT REDUCTION TABLES FOR AIR NAVIGATION, Pub. No 249, Commercial Edition
Volume 1 - Selected Stars Epoch 2010
Volume 2 - Declinations 0 to 29 degrees north and south; Latitudes 0 to 40 degrees north and south.
Volume 3 - Declinations 0 to 29 degrees north and south; Latitudes 39 to 89 degrees north and south.
Reproduced from US Government published tables. Pbk, 215mm x 265mm.
These are exact reproductions of the official US and hence British tables for sight reduction.
Volumes 2 and 3 are perpetual, volume 2 being the most wanted as it covers all voyaging between the most frequented parallels of latitude, 40 degrees north to 40 degrees south. The declination limits allow sights of the sun, Moon and navigational planets, as well as the majority of navigational stars.
Volume 1, Selected Stars, includes stars having declinations beyond the limits bounded by volumes 2 and 3, and also serves as a means of predicting star azimuths and altitudes for planning early star sights to allow the use of a well-lit horizon. This volume also serves the same purpose as and eliminates the need for a star identifier. Each edition of Volume 1 covers only a five-year period.
