By Bill Anderson. Pbk, 172mm x 240mm, 126 pages, full colour drawings and photographs.
The Global Positioning System has revolutionised small boat navigation.
A GPS set gives your position to within 20 metres, anywhere on earth. Punch in your destination and the machine gives the data you need to sail or motor to your target. The dream of navigators through the ages - always to know exactly where they are and where they are going - has finally been realised.
GPS Afloat explains, to the novice or traditional navigator, what the system can and cannot do. in a very short time you will be entering Waypoints, planning Routes and watching the Crosstrack Error as though they were old friends. You will also understand how to check your results using traditional navigation, common sense and the Mark 1 eyeball.

CAPTAIN RUDE STAR-FINDER 2102-D.
The unit consists of a base plate (northern hemisphere on one side, southern on the other) plus a set of latitude plates. Use the nautical almanac to look up the Greenwich Hour Angle of Aries for the time of interest (usually Civil Twilight - also obtained from the nautical almanac), then set the closest latitude disk on the base plate. Rotate the arrow on the latitude disk to the Local Hour Angle of Aries on the graduated edge of the base-plate, and you have in your hand a picture of the sky around you, showing the stars visible at twilight. From the disk you can read the azimuths (bearings), and altitudes (angular height above the horizon) of the stars. The planets, sun and moon can be marked in pencil onto the base-plate for a specific date and their approximate positions in the sky obtained at the same time as the starts.
This is an invaluable device for celestial navigators and also useful for more general star-gazing. The star-finder should be a complimentary tool to the sextant in any blue-water navigator's kit.

BRITISH ADMIRALTY TYPE STAR IDENTIFIER
This tool, like that above, is used to predict the bearing from true north (azimuth) and angle above the horizon (altitude) of the brightest stars. It is used for setting up star sights so that observations can be made using a firm horizon, by pre-setting the sextant and looking over the compass. In this way stars can be observed through the telescope before they are easily visible to the naked eye.
Star sights using this technique are much more accurate than if taken when the sky is dark enough to recognise the stars in constellations with the naked eye, due to the superior quality of the horizon. The instructions provided with the identifier are explicit.
Planets can also be pre-set using the identifier, enabling daylight sights of Venus and occasionally Mars and Jupiter.
The main point of difference with the 2012-D above is the quality. The British Admiralty type has a card base-plate and wallet whilst the 2012-D is of strong plastic throughout.

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.

REED'S SEXTANT SIMPLIFIED
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. This book describes how a sextant works, provides practical tips and advice on using it, explains how to read as well as take sights, how to make adjustments and correct errors, and finally advises on how to handle and care for the instrument.
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.
This book was designed specifically to facilitate the work of instructors using the free PowerPoint slide presentation available at CelestialNavigationBook.com. This exercise manual, available in hard copy and in PDF format for tablets, reproduces the questions posed at regular intervals throughout the slice presentation; it provides the work-forms guiding the calculations, and the solutions.
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.
This complete version of the exercise manual, with all the required data tables in the appendix, will thus be useful mostly to navigators who do not have the course book but wish to practice on their own, as well as to students who follow the presentation and have the course book but do not wish to download and print 140 pages of questions and answers.

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.
