Navigation -- indeed all of seafaring -- is a pretty conservative, traditional activity. It's pretty dangerous out there and people have a tendency to choose the devil they know (ie, tried and proven ways) over the devil they don't (newfangled stuff which might bring a whole lot of benefit or might catastrophically fail). While I have less fear of electronic navigation than others, I would choose the sextant. My reason is that while I might have many, many cloudy days where I would have to depend on DRs, short of dropping it overboard, a sextant can't catastrophically fail the way a GPS can (for sure, it's a pretty improbable event, but like a hole in the boat, you're in pretty deep sneakers if it does occur). NOW, to make things really interesting: Russell's question is a bit unfair in that the sextant choice costs more than twice the cost of a GPS, so let me pose a variant: If you had a choice of TWO GPS's or ONE sextant, which would you choose? I would flip-flop and choose the pair GPS's. While any single GPS has a tiny chance of catastrophic failure, the chance of both failing is far, far less than other more significant and life-threatening catastrophes which one might experience on the cruise. As the old saying goes, "the prudent navigator does not rely on a single source of information." While I would still be dependent on those satellites in the sky, once the signal leaves them I've essentially got two independent navigation systems. Looking forward to other's opinions.
