The 12th edition of this bestselling book is proof of the
success of Mary Blewitt's concise and clear style in explaining a
particularly difficult skill, and it has been the bible for many
generations of ocean navigators.


Since this book was first published, the huge advances in electronic
navigation have transported most offshore navigators to a world of
press-button convenience. However, there is still a vital need for
traditional skills when things go wrong: batteries can fail, aerials go
overboard, and electronics have been known to get wet.


A bestseller for over 50 years, Celestial Navigation for Yachtsmen is
a model of simplicity and clarity. The worked examples require only
straightforward addition and subtraction, which explains why this book
has truly earned its reputation for admirable conciseness and for
making a tricky subject easy to understand.
