Accuracy of Sight Reduction Methods.
In my recent article ‘Why Astro‘, I highlighted the risks in using the GPS. Since writing that article, I am frequently asked “if astro / celestial navigation is to be used, which of the many systems is the best”. Sight … Continue reading →
Short Distance Sailing And Rhumb Line Sailing
In my previous post about the meridian passage long method, I demonstrated how the ‘Short Distance Sailing Formulas’ are used to calculate a vessel’s position at meridian passage. I have since received several questions asking how these formulas allow for … Continue reading →
