I am now a fully paid-up and insured cabin boy aboard the good ship Lord Nelson, pressed to take passage north up the Irish Sea in May. Will Nelly keep a sextant and chronograph? All I will need then is a clear civil twilight, a flat horizon, sight reduction tables, an astro-globe, nautical almanac, a chart … or Google Maps. Handsomely now, me hearties. Keep sending the treasure!
