Franz Schulze was the director of the navigation school in Lübeck and thus an expert on all matters related to maritime science. This book from 1898 served as a practical almanac for the entire nautical operations on merchant ships of that time. It contains all essential information on terrestrial and astronomical navigation, an overview of all nautical instruments, and much more. Anyone interested in traditional navigation, such as on board classic ships, cannot overlook this well-written foundational work.
