About The Course…

This course covers how to find position at sea from timed sextant sights of the sun, moon, stars, and planets plus other routine and special procedures of safe, efficient offshore navigation. No previous navigation experience is required — the only math involved is arithmetic (adding and subtracting angles and times). This is a practical, how-to-do-it course, which also includes clear explanations of how it works and how to do it well. Plus this course includes other crucial factors of ocean navigation besides just finding out where you are from the stars, such as logbook procedures, dead reckoning, error analysis, route planning, etc. At the end of this course, you will be ready for ocean navigation. Thousands of students have successfully learned celestial from these materials and gone on to cross oceans or circumnavigate the globe.

And you will not be left studying on your own. Registered for the course, you are just a keyboard click away from individual personal help whenever you need it.

All text materials are provided to complete the course. The only thing extra you might need are basic plotting tools (parallel rules, dividers and protractor). If you have no tools now, then our plotting tool kit will provide what you need… not just for the course, but for all of your future navigation underway as well.

You do not need a sextant to work the course.

With the electronic components, you can take the complete course with you as you travel, or use it to search the complete set of materials for specific topics. If you prefer to work on your own without computers, you have a complete syllabus with practice exercises and answers in the printed materials. If you want extra structure to your training, then take part in the online course for more discussion and individual quizzes at each lesson.

Each course includes free access to online Resources and discussion groups. The Student Discussion Groups are similar to Public Discussion Groups, but they are much more extensive including all classroom discussion since 2003.
