Pub. No. 229 is way too cumbersome to lug around so I solve for Hc and Zn using the respective formulae for them.
These are handy to carry- http://thenauticalalmanac.com/Formulas.html
and a lot lighter than books.
Messing around with the various formulae to determine Z led me to the one on the Formulas page. Most of the others require too many conditions ("if, then") to arrive at a solution.
Would like to hear what others use or maybe a quicker method.
