Few people in America understand just what the maritime industry is and its main component - the merchant marine, and few realize how this industry profoundly affects every American, every day.  In the second part of his 2-part presentation, Christopher McMahon continues his detailed look at the industry and the ships which make global trade possible.  Simply put, the global economy is completely dependent on the maritime industry.  Admiral McMahon will also touch on just how Chatham Radio/WCC played a key role in keeping merchant ships in touch with their companies, the ports which they served, and how WCC helped ensure that ships and crews remained safe in times of extreme weather and other perils.
