NAVIGATION 2, ASTRONOMISK NAVIGATION, TIDVATTEN

Bengt Stahl & Bjorn Borg - 2nd printing "Navigation 2" is written with the intention to provide the reader with the theoretical and practical knowledge necessary to enable him to easily perform ortlinjeberäkningar and calculations of tidal heights and tidal currents. A supplementary booklet to Navigation 2 was released in 1983 due to the methods of calculation and layout had been changed in the British tide table work. This booklet is now incorporated in this edition of "Navigation 2".
