Yes.  A principle means of establishing latitude on land, where a plumb
bob or spirit level can be used to establish one's "horizon."  At sea,
with only a short time at twilight when both the real horizon and stars
are visible, tough to find a star undergoing meridian passage (and
wasting time better spent obtaining a 3-point or 4-point fix).

Without trying to speak for George, I didn't get the impression that he
felt slighted, rather delighted to once again share his erudition, much
to our benefit.
