- Marlinespike/basic knots
- And other interesting topics
Learn the essentials of safe coastal and inland navigation using basic GPS in conjunction with charts and other marine data. The Coastal Navigation course teaches you how to use the GPS along with traditional dead reckoning techniques for planning and laying out safe routes, as well as ensuring that you are on-course while underway.
- Charts and their interpretation
- Landmarks and navigation aids (buoys, daymarks, lights, etc.)
- Plotting courses and determining direction and distance
- The mariner’s compass and converting between True and Magnetic
- Use of GPS – basic GPS displays and information they provide, setting up waypoints and routes, staying on a GPS course
- Pre-planning courses and entering them into the GPS
- Monitoring progress and determining position by both GPS and traditional techniques such as bearings and dead reckoning
- The “Seaman’s Eye” – simple skills for checking that one is on course
Advanced Marine Navigation
Do you want to navigate unfamiliar waters in limited visibility or take an extended cruise with confidence? Learn to use radar, chart plotters, AIS and other electronic tools to supplement basic GPS navigation. Obtain a thorough understanding of piloting techniques in a variety of coastal tide, current and wind conditions.
- Advanced positioning techniques, such as advancing a line of position to obtain a running fix
- Use a variety of electronic tools: radar, depth sounders, autopilots, chart plotters, laptop computer software, and more

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
- Taking sextant sights of the sun
- Reducing sights to establish lines of position
- Determining latitude from a noon sight
- Using special charts and plotting sheets for offshore navigation
- 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
