HANDY JACK BOOK OF NAVIGATION TABLES

This classic publication belongs to the famous and historical The Rudder ON series. The nautical books and other instruments that are commonly used on board marine ships for navigation are usually quite large sized. This does not present any sort of problem on large conventional vessels since there is lot of space available to keep and use them.

However, on smaller ships the crew members usually prefer more compact volumes. That is the reason why the decision was made by the author of this publication to reduce its size to the maximum practical extent. In the meantime every effort was made to include all important information. The volume opens with a chapter devoted to the altitude diagrams also explaining dip of the horizon and parallax.

There are numerous tables included in this section addressing main refraction, difference of latitude and departure for degrees from 1 to 45, log. sines, tangents, and secants, dip of the sea horizon, the Sun's parallax in altitude, correction of the Moon's altitude, and comparison of Admiralty knots and statute miles. The remaining portion of the publication is dealing with using sextant, etc. In short, the book will be interesting for the people who like navigation and are interested with the traditional navigation techniques.
