Description
Norie's Nautical Tables is the essential requirement for anyone learning and practicing astronavigation.
Since J W Norie published the first edition of his Complete Set of Nautical Tables and Epitome of Practical Navigation in 1803, many changes to the tables have been necessary in both content and presentation. New tables have been included, 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.
Since the commissioning of the Global Navigation Satellite System (GNSS), 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. Its use is widespread but the marine environment is a hostile one and failure of electronic equipment or of the system itself is a possibility. No prudent seafarer would proceed on an ocean passage without a reliable navigational back-up. The Explanation is in the form of a detailed step-by-step description, by means of worked examples, of the different methods of performing navigational calculations using a scientific calculator and/or the tables.
A number of esteemed editors have worked on Nories' Nautical Tables over the years and this edition includes contributions from Francois Hugo and an updates Seaports of the World section. It presents formulae in an appropriate format for direct entry to a scientific calculator. Because the possibility of navigation without even an appropriate calculator exists, the logarithms have been retained.
* All the tables required for coastal and deep sea navigation are included
* A simple uniform method of interpolation for all the trigonometrical tables is used
* Certain tables and data are also included which are not readily available on board ship or are only used in the examination room.

Person
Imray Laurie Norie & Wilson Ltd was formed in 1904 when three private chart publishing firms amalgamated. Each of these London companies had a long history going back to the mid-18th century. James Imray and Son published an extensive list of charts and pilot books. RH Laurie and Sons was associated with charts published for the East India Company. Norie and Wilson, founded by JW Norie, whose Nautical Tables are still supplied to navigators across the world, produced charts and books on navigation and sold nautical instruments.Until 1939 we were based in the City of London, where long serving cartographers produced charts from copper plate engravings which were supplied to mariners throughout the World. For over a century Blueback Charts were the first choice of many shipping companies. Now based in St Ives in Cambridgeshire, Imray charts are produced digitally for printed and electronic editions by our drawing office team. Our catalogue of yachting charts is regarded by the sailing community as the most comprehensive available. Our paper charts are complemented by a growing list of electronic publications and high quality pilot books by leading authors.
