HERE ARE THE CORRECT ANSWERS

THE HANDBOOK OF PRACTICAL NAVIGATION
This test is from our “Practical Navigation” handbook
in the “Secrets of Going to Sea” series, now on superoffer. In this 290-page volume we have rounded up everything that may be essential for a good basic knowledge: from setting a course to rules for preventing collisions at sea; from mooring and anchoring maneuvers to knowledge of the main weather phenomena, going so far as to work out a local “weather” forecast. To end with notions for dealing with bad weather. “Practical Navigation” is aimed at those who make long-shore sailings, as well as those who want to take on challenging deep-sea cruises. Indeed, this is the baggage that every skipper must possess, whatever type of vessel he or she will be sailing with. The exposition of every single word in this volume comes from the practical experience of thousands of miles of sailing.
