I don't get joe'spoint about noon sun shots. My understanding is that, as far as latitude is
concerned, the when is irrelevant, only the height matters and the slower it
changes the better your accuracy is.
And although I know this is real heresy, I have crossed the Atlantic Ocean
from Newport to Saint Malo via the Açores (or whatever you call these
islands in english) on a small yacht using only noon sun shots to determine
both latitude and longitude, and managed to land securely (the accuracy on
longitude was lousy, but still good enough to know when you have to be
careful). So I think the method is great and, yes, very simple (but maybe, in these GPS days, simplicity is not anymore the best reason for using astronomical navigation).
