Nathaniel Bowditch was born in Salem, Massachusets in 1773. He is frequently credited with being the father of modern maritime navigation. A brilliant and largely self-taught mathematician, Bowditch became interested in celestial navigation while at sea. His book American Practical Navigator has been so influential since its first publication in 1802 and through its many revisions that mariners refer to it simply as "Bowditch." On the Sunday after Nathaniel Bowditch died in 1838, his son Nathaniel Ingersoll Bowditch memorialized his father's life and accomplishments to students at a chapel built especially for poor children in Boston. In 1841, these recollections were published in this memoir.

Many useful tables and glossary of marine navigation are in volume IIDue to critical feedback from academia, the 2017 edition reconstitutes several deleted or abridged chapters removed from the previous two editions. The additional text warranted the return of a two-volume format with the useful tables and glossary of marine navigation located in volume II.CHAPTER 1, MATHEMATICS CHAPTER 2, INTERPOLATION includes discussion on single, double, triple and nonlinear interpolation (with Bessel's formula included). CHAPTER 3, NAVIGATIONAL ERROR The chapter goes into greater depth on the subject than the 2002 edition.CHAPTER 4, CALCULATIONS AND CONVERSIONS summarizes the formulas the navigator depends upon during voyage planning, piloting, celestial navigation, and various related tasks. CHAPTER 5, COMPASS CONVERSIONS contains information on magnetic compass error, deviation table, applying variation and deviation, along with several example problems. CHAPTER 6, COMPASS ERROR
