The American Practical Navigator, first published in 1802, was billed as the “epitome of navigation” by its original author, Nathaniel Bowditch. The text has evolved with the advances in navigation practices since that first issue and continues to serve as a valuable reference for marine navigation in the modern day.
The publication describes in detail the principles and factors of navigation, including piloting, electronic navigation, celestial navigation, mathematics, safety, oceanography and meteorology. It also contains various tables used in typical navigational calculations and solutions, including the formulas used to derive the tabular data.
The Celestial Navigation Information website is a community of members who are interested in the practice of celestial navigation. We feel the science and art of navigation is of fundamental importance on all voyages whether on land, sea, or in the air. We think the celestial way, although ancient in origin, is still the most exciting way to navigate.
