Question asked by James:
Are you familiar with or do you ever use a sextant to confirm your positions?
We do have sextant aboard, yet so far I have not checked the GPS (Global Positioning System) against it. When I started long distance sailing there were no electronic position aids, so my first trans-Atlantic voyage was done using a sextant. It is very satisfying after a few weeks at sea, to have an island show up where and when it is supposed to show up. That is just amazing.
Thanks for the question,
