Von der hinteren Coverseite

"Calder has done it again. This comprehensive and, as importantly, readable book on navigation should be required on all boats."--Peter Nielsen, editor, SAIL magazine

"This is a wonderful chart companion: an intriguing investigation of chart development combined with practical, hands-on data on how to really put a chart to use."--Tim Queeney, editor, Ocean Navigator

Charts, whether paper or electronic, are your most fundamental navigational tool. Using them to your best advantage requires a thorough understanding of the symbols and abbreviations and an awareness of the limits of accuracy in positions and soundings.

Did you know, for example, that hydrographic standards used to collect the majority of data on modern charts are considerably less accurate than GPS position fixes? That the majority of soundings still come from lead-line surveys? That a wreck symbol surrounded by a dotted circle means it is considered dangerous? That there are four different kinds of rock symbols, each with a different meaning? And that the definition of "danger" has changed over time and will depend on the age of your charts?

In How to Read a Nautical Chart, trusted boating authority Nigel Calder answers these and hundreds of other questions clearly and concisely. He covers in detail:

• Fundamental chartmaking concepts in plain language
• The limits of accuracy of modern charts (paper and electronic)
• Dozens of full-scale illustrations from actual charts
• Expanded versions of U.S., British, and international chart symbology descriptions contained in NOAA's Chart No. 1, the British Admiralty's Chart 5011, and the IHO's INT-1
• And much more essential information designed to improve vital chart-reading skills

How to Read a Nautical Chart should be on every navigator's bookshelf.

"Nigel's enthusiasm and insight turn a mundane chart into a map of buried treasure. Every navigator should stow a copy in the chart table."--Paul Gelder, deputy editor, Yachting Monthly
