Captain Jack I. Davis has done it again! He has written yet another, very easy-to-understand, instructional navigation book. As in his first book, this book is filled with knowledge, new sea stories and more humorous anecdotes. Using the same highly successful format of his first book, Captain Jack takes the reader through each phase of navigation by first explaining, in detail, the steps needed to complete each phase. This is followed by a list of questions to answer, using your new found knowledge. After you have completed the questions, you can check your answers at the end of each chapter. All the calculations are accomplished with simple mathematics using an inexpensive calculator and basic plotting tools.
