In the list of the recommended navigational instruments are the H. O. 259 tables which are in a very wide use among the amateur marine navigators owing to their simplicity and ease of use.

In fact, there are no pre-requisites for using this book - the readers are only expected to be able to read, add/subtract, understand the angles and know how to use the protractor. Al sailors will for sure enjoy this volume, regardless of their experience - the content of this classic book will definitely be equally useful and interesting to everyone from armchair-navigators to the racers and circumnavigators. The celestial navigation, i.e. steering by the stars is the art perfected by the seafarers of ancient Polynesia navigating over thousand years before Europeans.
