I strikes me I sort of ignored your specific "Cel Nav" query in my last
response.

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 ;-)
