Captain Jack's Complete Navigation is a combination of Captain Jack's Basic Navigation and Captain Jack's Celestial Navigation. This is truly the most complete and easy-to-understand navigation package you will own. After traveling thousands of miles on the water and teaching hundreds of navigation and boating courses, Captain Jack has put his vast experience into this excellent book. Filled with knowledge, sea stories, and humorous anecdotes, this book is not only a learning tool but also thoroughly enjoyable to read. He has even thrown in a few boating lessons to help you at sea. 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, grade school math using an inexpensive calculator and basic navigation tools. If you believe you do not need these Old Time navigational skills in this modern age of electronic navigation, Captain Jack makes this suggestion to you: "Tape a mirror below your GPS display. When the electronics fail, you can look in the mirror and see exactly who is lost."
Book Description
Editorial Reviews
From the Author
PART ONE - BASIC NAVIGATION I have about 30,000 blue water sailing miles behind me plus another 5,000 blue water power boat miles. Add to that 5,000 very boring Intracoastal waterway miles and some 1,000 three or four hour sailing lessons and you can see I've spent a lot of time on boats. Most of this time has been thoroughly enjoyable.
Some of the less joyful things are storms. Storms at sea are not much fun and storms lasting for weeks at a time are not much fun for weeks at a time. We have to take the bad with the good.
When I first started to teach sailing courses, I was surprised at the satisfaction I derived from the experience. For me, there is a sense of accomplishment which didn't exist in many of my other endeavors.
After going through the basics of sailing, many of my sailing students wanted to further improve their knowledge of the sea. This led me into teaching my first navigation classes.
Teaching these navigation classes was satisfying, but frustration began when I could not "get through" to many of the students. I learned that most of these "slow students" weren't slow at all. They just had an inept instructor. ME!
By refining my techniques and borrowing ideas from others, I found I had fewer and fewer "slow students". This book utilizes the same techniques as a method for the reader to become a competent navigator.
The format presented here is the classroom presentation. Included is my practice of interspersing many of my sea stories with the real work. Of course, these are the same stories my former students are already more familiar with than they want to be.
Many of my explanations, diagrams and procedures have come about as the most practical way for me to introduce newcomers to the navigational procedures on a boat. They may not reflect absolute scientific explanation but they will teach you what you must know.
I must admit, I've picked up many ideas and techniques from others. Too numerous to mention them all but I do want to acknowledge a few of the main ones.
First, many years ago I took an "Intermediate Navigation" correspondence course from the University of Tennessee. This was my first and only venture into the academic aspects of navigation. It was a good venture, and in reviewing my teaching methods, I see the influence of that well structured course.
Second, in preparing for my first U. S. Coast Guard captain's license examination, I reviewed a book by Richard A. Block, published by Marine Education Textbooks. His navigation presentation was by far the best and most comprehensive of any on the market. I know my teaching methods have been greatly affected by Mr. Block's work.
Third, the number one authority on navigation, in my opinion, is Bowditch. I use both Volumes I and II extensively.
Last but not least, I must acknowledge and thank the hundreds of sailors I have sailed with through the years. I have learned something, from nearly every one of them, which influences my teaching and definitely my sea stories.
I want to especially thank Lynn Pinkerton and Sandy Billings for encouraging me to write this book and my first mate, Mary, for spelling and grammar lessons I somehow missed in school. Joe Kolb for artwork and friendship. Mike Sutton my sailboat neighbor, who worked the problems and checked the answers.
PART TWO - CELESTIAL NAVIGATION
With the incredible advances in electronic navigation equipment, especially the development of the satellite system, small boat navigation is so simple I'm surprised anyone would make the effort to learn basic navigation.
The greater effort of learning celestial navigation, I thought, would be an effort that would go the way of the dinosaurs. To my surprise basic navigation is in good demand and I have more requests for classes in celestial than ever before.
There remains a fear the electronics may fail. To a greater extent my students want the security that comes with knowledge and in the case of celestial, they want the bragging rights. Very few sailors ever get far enough along with the study of celestial navigation for it to be useful to them. Most sailors at a yacht club bar will begin to fade away when a few sailors start talking about reducing sights, cocked hat star sights, etc.
Before the electronics age, most long-range sailors who claimed to know celestial navigation, only understood the "noon sight." As you will learn the noon sight is a very small part that can be learned by almost anyone in a matter of minutes.
When I decided to go cruising, I knew I had to learn celestial because the only electronic aid available at the time was the old Loran A, a huge, expensive instrument, which I knew I couldn't afford on my limited budget.
I read that people would sit on the end of a dock and learn celestial from a boat neighbor, but I didn't know anyone who knew celestial. In one sailing magazine story a new sailor picked up a book on celestial navigation and after a few hours reading was qualified to go around the world using his sextant. If it's that easy why don't I just dig in and learn? I tried not one, but several books on the subject and after many days of reading had not learned anything. During the fifth book the light finally penetrated my thick skull and I started to enjoy the learning experience. Many more days went by before I could honestly say, "I understand."
After arriving at this understanding, I spent several months getting the boat ready to go. Shortly before it was "cast off" time, I realized I couldn't remember enough celestial navigation to work a sight. To my chagrin it was almost as hard to relearn celestial navigation as it was to learn it in the first place.
Finally, all came together and I began my cruising life, with my celestial navigation working very well. This sort of life came down to a few days of sailing and weeks of hanging on the hook, gunkholing and exploring, amounting to nothing more than coast piloting. When it was time for the second leg of my cruise, I had forgotten celestial again.
All in all, I probably relearned celestial navigation six times, with each time being virtually as difficult as the first time. It wasn't until I agreed to teach celestial navigation to a group of my sailing buddies that I got the material organized well, thereby getting it straight in my mind. Using this organization as a technique in the class room I find my students are better able to remember what they learn. Part of this technique involves NOT using preprinted forms. With forms, the student is learning how to fill out forms and retains very little of the purpose behind the procedure. If the navigator addicted to forms runs out of forms or -- God forbid -- they get blown overboard or soaked with sea water, then he is no longer able to find his way. That would be no different than having a GPS with dead batteries.
Please understand my methods are not necessarily scientific perfection. They are more of a method for you to find your way with a sextant, reducing the sights on the back of a matchbook while leaning against the mast, if it is ever necessary to do so.
About the Author
Captain Jack I. Davis and his first mate Mary (Mary is an excellent sailor and registered nurse), have lived aboard their forty-three foot Wauquiez ketch since 1984.
His first career was banking and his second career was computer software for banks but his main love has always been sailboats. During this time he owned several power boats and enjoyed water skiing and fishing but yearned for the blue water which the Texas lakes did not offer.
He had made several ocean crossings before obtaining his first U. S. Coast Guard Captain's License in 1984 at which time he started boat deliveries in earnest.
The majority of the deliveries have been from Texas to Florida and the West Indies with one delivery completely circumnavigating the Gulf of Mexico. In May 1998, he made his sixty first open water crossing of the Gulf of Mexico.
Between deliveries he has taught countless sailing and navigation classes. His sense of humor and teaching style, as demonstrated in this book, keep his students coming back for more. He has continually upgraded that first license and now holds a U. S. Coast Guard Master's License, Steam, MotorSail and Sail.
