Lu Abel, in a posting with subject "Haversine formulae for Great Circles", says- >For sailing (which IS the focus of this group, of course) mid-Lat would be >just fine (Mercator Sailing gives a rhumb line course so it wouldn't be >applicable) This puzzles me somewhat. In the context we are discussing, (when the destination is very close to the point of departure), then a rhumb line and a great circle become indistinguishable.
