Traditional Celestial Navigation and Chartwork
Welcome to Our site. We provide rigorous, methodical instruction in classical ocean navigation. Learn to determine your vessel's position at sea using nothing more than a marine sextant, an accurate timepiece, nautical almanacs, and paper plotting sheets.
The Curriculum
In an era dominated by electronic satellite positioning, understanding foundational navigational principles remains an essential competency for offshore mariners. Our educational sessions focus on error analysis, sight reduction mathematics, reduction tables, and piloting by visual and celestial bearings.
Participants examine the mechanics of the metal arc, index error correction, and the precise timing required for lunar distance methods and meridian altitude sights.
Upcoming Seminar Topics
- Sextant calibration and verification of index mirror perpendicularity
- Reduction of sights using the intercept method (Marcq St. Hilaire)
- Construction of plotting sheets and dead reckoning management
- Identification of navigational stars using traditional planispheres
