What happens when your GPS fails? Have fun and satisfy your curiosity about boating in the days before electronics in the Offshore Navigation course. Learn to use a marine sextant to take sights on celestial objects such as the sun. Even if you are not traveling long distances offshore, remember that GPS is not infallible, nor always available. Be confident when no aids to navigation or land objects are in sight.
In Offshore Navigation, you will continue to use GPS as the primary position sensor as you learned in Coastal Navigation and Advanced Coastal Navigation, but with celestial navigation as your backup technique. Because terrestrial landmarks are no longer visible to the offshore navigator, you will learn to use a marine sextant and the sun as your reference point, derive a line of position, and develop a running fix. You will also learn to calculate your latitude from a noon sight on the sun.
Finally, Offshore Navigation introduces watchkeeping and other techniques of cruising on the open ocean. These time-tested procedures are good skills to have even along the coast.
- Determining precise time
- Using the Nautical Almanac

- Setting offshore navigational routines for recreational craft
Learn navigation using all the celestial bodies! Use navigational software tools to plan and execute an offshore voyage. In the event of a loss of electronics on board, you’ll be glad you took this course and developed the necessary backup skills for an offshore voyage. Even if you have no plans to travel offshore, you will be able to impress your boating friends with your depth of celestial knowledge.
The Celestial Navigation course will teach you how to use the moon, planets, and stars to determine your position at morning and evening twilight to supplement daytime sights on the sun, moon, and bright planets. You will also get access to and use navigational software tools that can be used to plan and execute any voyage.
- An overview of how the celestial bodies in the sky appear to us on earth
- Finding local mean time of solar and lunar phenomena and converting these times to watch time
- Reducing sights of the moon, stars, and planets by the Law of Cosines and Nautical Almanac Sight Reduction methods, along with sight data averaging
