Can you talk more about how you did navigation once GPS was dead? I know it's a broad question but there's a lot of us that probably don't know anything about navigation. Did you use a sextant? How did you estimate your lat. and specifically long.? How did you correct for current, tidal forces (if any)? Did you know the formulas by hearth or did you have books? Which ones? Is this "lost" as in no modern technologies or as in "lost" - actually not quite knowing where you are or where you're going?

Stuff like that.

That sounds like quite an ordeal. Did you have any magnetic maps? I know some areas have varying local magnetic fields so you can miss easily by just following the compass and estimating distance traveled by speed.
