The bible for many generations of ocean navigators, and a bestseller for over 50 years, this book explains a particularly difficult skill in a concise and clear style. Since it was first published, 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. The worked examples in this book require only straightforward addition and subtraction, which explains why it has truly earned its reputation for admirable conciseness and making a tricky subject easy to understand.
