Illustrated with exceptionally clear diagrams and photographs, but with simulated radar screen pictures, chapters cover basic principles: installation; setting up and use of controls; capabilities with use of VRM and EBL; head-up vs. north-up displays (the latter is favoured, unusually for small boats); collision avoidance and use of plotting sheets; navigation/pilotage; integration with other aids. Appendices cover radar bands, radar horizon and range, relevant extracts from Colregs, and a glossary of terms.
Although simulated radar pictures are ideal for demonstrating ship and land echoes and clutter, I prefer actual screen photographs which give a much more realistic impression of operation, together with extracts from charts covering the screen area. The use of clutter controls to reduce rain clutter, which can be of greatly varying degree, and gain controls is much better demonstrated with real pictures. Interpretation of sea clutter which can clearly warn of overfalls is not mentioned.
Too many yachtsmen buy expensive radar sets and rely on their manuals for operation and interpretation. Further study is essential to realize the true potential of radar on small vessels. This book covers all relevant aspects. A similar book was published in 1998, and prospective users should compare the two before purchasing. - RMG
