Interesting stuff, really. Frank, when you have logbooks opened, do you realize, how the chronometer and lunar longitudes were used for the following navigator's day work? Was the next reckoning started from them? From the chronometer or from the lunar longitude? (Probably after shifting them to the noon?). Or were they used for obtaining the course to steer at least, as in Norie's Epitome from 1831? Or were they left aside and DR longitude remained the starting point for both the reckoning and for aiming at the point of arrival throughout the all voyage as in the contemporary Bowditch (1851=1838)?
