Nories Nautical Tables (Revised Edition) - Francois Hugo

"Nories Nautical Tables (Revised Edition)" by François Hugo is an indispensable resource for students, cadets, professional seafarers, and anyone involved in astronavigation and practical marine navigation. Since the publication of J.W. Norie's first Complete Set of Nautical Tables and Epitome of Practical Navigation in 1803, the tables have undergone continuous updates to improve both accuracy and usability. This revised edition reflects the evolution of navigation techniques, introducing new tables while removing obsolete material to ensure relevance in modern maritime practice.

Despite the reliability and widespread adoption of Global Navigation Satellite Systems (GNSS), electronic systems remain vulnerable to failure due to technical issues or harsh marine environments. Every prudent navigator understands the necessity of maintaining dependable navigation backup systems. This edition provides detailed step-by-step explanations and worked examples demonstrating different navigational calculation methods using both scientific calculators and traditional tables.

The book also retains logarithmic methods, ensuring navigators remain prepared even in situations where advanced calculating equipment is unavailable. In addition, it includes an updated Seaports of the World section and formulas adapted for direct use with scientific calculators.
