Created to be small and compact for easy traveling, this study guide provides all the lights, shapes, and symbols used out in the sea. How do you signal that a vessel is in distress or has run aground? International signals and symbols are also provided, as is an alphabetical listing of phonetic and Morse Code. In addition to preparing marine students, this book is a valuable tool for the seasoned mariner or private boater who wants to sharpen their skills and make themselves safer and more prudent on the water. Its cargo-pocket size and lightly laminated pages means it can be taken on the "road" with the marine and endure in a maritime environment. AUTHOR: Captain Green is a former military special warfare operator who now serves as a U.S. Merchant Mariner and public safety bomb disposal specialist.
