    I strikes me I sort of ignored your specific "Cel Nav" query in my last
    First accept that anything done on a small craft is AT LEAST twice as
    hard as doing it on land (at least for those of us not as sea on a small
    craft for very long periods of time). For me, that includes making
    sandwiches and cognitive tasks.
    Second, Cel Nav is not GPS (instantaneous feedback) or coastal piloting.
      Its primary use IMHO is crossing vast expanses of water.  Hopefully
    you can calculate where you were at a given point in time with
    reasonable precision/accuracy given the circumstances at the time.
    Therefore there is no reason to bury you nose in a book until you are
    feeding your lunch to the fish. Slow down, take it one step at a time
    and take a break--before needed.
    The captains of old were using log tables/haversines and a slate tablet.
      Given an NA and calculator, what's your rush ;-)
    Bill B.
