Has your friend expressed an informed opinion as to whether he wants a sextant? I wouldn''t leave the dock without one, but I enjoy celestial nav. I was in Marina Del Rey a few years ago to see off a friend in the Pacific Regatta, a non-stop race to Japan. I talked to at least a dozen other skippers, none of which was carrying a sextant. I asked each what they would do if their GPS crapped out, and every one said they had at least one back-up GPS. Made me feel like a dinosaur.
