Astro-navigation & ocean passage planning
"This is the best RYA theory course"
Perhaps GPS and chart plotters make us think it's not necessary to learn about celestial navigation these days. But aren't you fascinated to know how mariners of old navigated by the sun and the stars?
"John is a first class instructor who presents what at times seems daunting material in a clear & easy-to-follow way. The online resources between Saturdays were excellent." Dave
While there are a lot of calculations involved in astronavigation, you don't have to do them yourself! It's more a matter of looking up the answers in tables.
If you can add or subtract minutes up to 60' & add or subtract up to 360°, you're good to go!
For example: Add 245° 51.7' to 120° 18'
The minutes total = 69.7' but that's more than 60 so it actually becomes 1° 9.7'
The degrees total = 365° + the extra 1° from the minutes, so that's 366°. This is 6° too many from the 360° available.
So the answer to the sum becomes 6° 9.7' and that's pretty much as hard as the maths gets!
