Thank you, Courtney As I recall, the instructions for doing this are printed in the almanac- you can use an old copy for sun/stars but not for planets/moon sights. Small boat sailors used sun sights most of the time, anyway. I'm pretty sure that both Moitessier and Gau would have been happy to read the lat/lon from the GPS screen..... John |
