Live Webinar begins : Wednesday January 27th!

This course is designed to teach you all of the old (celestial - using only the celestial objects, sun, moon, stars and planets) navigation tricks used by the sailing masters prior to the age of electronic navigation.

This is open ocean navigation, not within the sight of land.


Although there are no official prerequisites for this course, many of the tricks from the Coastal Navigation course come into play, so it is very wise to have completed a Coastal Navigation course.

Upon Completion:

You will have been taught all of the most common techniques used for 100's of years to navigate across  the worlds oceans.  The assumptions of the course are that the engine died long enough ago that there is no longer any electricity available - therefore no GPS or any other form of electronic navigation.

Starting Dates:

Live Online Webinars:  This class is only taught by an instructor, online, typically on Wednesday evenings, starting mid February each year, running from 7:00 p.m. to 10:00 p.m. MST.  For the year 2021, the webinars will be starting on Wednesday, January 27th, 2021.  Recorded sessions are available at any time.

Recorded Sessions:  Since all of the sessions are recorded it is possible to start at any time and run through the recorded webinars at your own pace.  For 2 years from the date of purchase, you will be considered an "Active" student and will have access to all of the videos and live presentations to complete the class.  You can reset the clock and retake the course for the cost of the materials package. 

Any "active" student can attend any of the live online sessions.

  12. Plotting of Celestial L.O.P. on a Universal Plotting Sheet using simultaneous sights or running sight methods.
