    Celestial navigation by sextant absolutely has a place in the modern world. It provides that "cross-check" that helps navigators maintain situational awareness, and it can detect spoofing on a coarse scale,

    As I type this I am listening to the heavy rain outside. It must be  several weeks since I last saw the sun. My DR position is hopelessly inaccurate and I am worried that I am approaching a lee shore (-;  Fortunately the GPS on my phone has not been zapped by lightening and works through thick cloud so I can confirm that my house has not drifted to a dangerous location!

    If you loose your electronics isn't it better to do so in lower latitudes than near lat 41S?

    Seriously, the important part of Frank's comment is "situational awareness". It seems to me that if someone understands cell nav (and pilotage) they are less likely to get into trouble than someone who merely watches an icon on a chart plotter. The reason being that they have made an effort to understand navigation. In my doctor's waiting room there are some boating magazines. They advertise chart plotters that allow the boat occupant to specify a route from A to B and the system will (or claims to) drive the boat safely around rocks and reefs - no skill required.

    My usual disclaimer:   I am an armchair navigator.
