How so? Dead-reckoning is not nearly as reliable as pilotage....


To send us off on another tangent, and one that I haven't seen mentioned
in this thread before, it's "ded-reckoning", not "dead-reckoning". The
"ded" stands for "deduced", not whatever "dead" might stand for other
than the obvious.

We now return you to your regularly scheduled navigation argument.


Hardly that clear. There are about as many references that say "dead"
as there are that say "ded."

Saying deduced reckoning is close to being redundant.
