The eleventh edition of this bestselling textbook is proof of the success of Mary Blewitt`s concise and clear style in explaining a particularly difficult skill. It has been the bible for many generations of celestial navigators.

When it was first published in 1950, ocean navigators would have been competent with sextant and tables, but the huge advances in electronic navigation have now placed most offshore navigators in a world of press-button convenience. There is, however, a vital need for traditional skills when things go wrong: batteries can fail, aerials go overboard, and electronics have been known to get wet.

This eleventh edition has been completely revised and contains new worked examples related to the current nautical almanac and air tables. The only mathematics involved are straightforward addition and subtraction, which explains why this book has truly earned its reputation for clarity, admirable conciseness and for making a tricky subject easy to understand.
