Well, I suppose I will ask since it is on my mind. This 'is' an aviation/marine oriented site and I am seaplane rated. (although Im nowhere near current) Has anyone deciphered/demystified the hocus-pocus math involved in using a sextant. I have tried a couple of times to master it, but I keep loosing interest since I am probably the only person within 300 miles who actually owns one. <br> Short of actually going to the coast and taking a class from the Coast Guard; does anyone have any ideas on how to make this easier?
