Radar and ARPA (Automatic Radar Plotting Aids) are standard systems on all commercial vessels and are widely used in the leisure maritime sector. This fully revised new edition covers the complete radar/ARPA installation and serves as the most comprehensive and up-to-date reference on equipment and techniques for radar observers using older and newer systems alike. Suitable for use both as a professional user’s reference and as a training text, it covers all aspects of radar, ARPA and integrated bridge system technology, its use and its role in shipboard operations. Reference is made throughout to IMO (International Maritime Organisation) Performance Standards, the role of radar in navigation and in collision avoidance, and to international professional and amateur marine operations qualifications.
* The most up-to-date book available, with full coverage of modern radar and ARPA systems, integrated electronic bridge systems and the 2004 IMO Radar regulations
* The industry authority text, widely-used
* Meets professional, educational and leisure maritime needs, covering both professional and amateur certificate requirements
