Yesterday, 25 June 2017, I was sailing in the South Atlantic aboard my 140-foot schooner "Sonho Acordado," and I was lost! Well actually, my sextant was lost for a few days, but finally it turned up, stowed in the wrong compartment (that's the trouble with such a large yacht). I took a sight of the Sun about three hours after local noon, give or take fifteen minutes. My raw sextant altitude was 29°20.5' at 16:48:30 UTC. There's no index correction since I always maintain my sextant with index error zero-ed out. My height of eye was 25 feet or so. And by good fortune, there was a rocky island visible on or beyond the horizon almost directly below the Sun. Where was I?
