re: Sextant and finding out where you aren't
My son has an app on his phone which identifies stars when you point it at them, its quite cool. You might have to get an Australian app if you want to find the Southern Cross.
Shpelling is not my forte.
The world may have moved on, I still find the old ways interesting, be it a hand lead with tallow to check the bottom, a hand bearing compass, a walker log. or a sextant. The techniques of Polynesians, Vikings and other ancient mariners are of interest.
local knowledge and pilotage.
Doubling the angle on the bow was part of the CYA basic Nav. when I did it a couple of decades ago, I can't remember if distance by vertical angle was or not. a running fix was. I don't think a horizontal sextant angle was. I certainly used them all at one time or other. though not often. I used mine for celestial much more than terrestrial nav
I don't know If the modern Yachtmaster includes these or not.
Just figured I found it interesting, and thought a few others might also.
A few hundred years from now, navigation may be more about astro physics and theoretical mathematics involving Einstein's theory of relativity. Or he might be wrong. The true navigators of the day who are worth their salt will still be interested in how ancient mariners did it.
They may also be interested in a sextent.
