Description
CELESTIAL NAVIGATION FOR YACHTSMEN
BY M BLEWITT
HARD COVER
There is deep mystery and profound satisfaction in finding your position on earth by reference to the sun, moon, and stars--not to mention profound relief when the GPS receiver stops working in mid-passage.
That is why knowledge of celestial navigation is still a rite of initiation, and its practice still a favorite pastime among serious cruisers
It successfully teaches sailors who have been demoralized by bigger books. It remains "the famous book" on celestial navigation.
The only mathematics involved are straightforward addition and subtraction. CONTENTS:
