Bill, in a PS, you wrote:

GPS is VASTLY superior to any of this traditional navigation. It's so
superior that it is hardly the same animal. But never mind that! We like
traditional navigation. But if we're gonna "sell it" to other people, I think we need
to do better than refer to chapter and verse in Bowditch as if it's Scripture.
If someone interested in learning traditional navigation tries out Table 15
and gets a distance that's a couple of miles away from their known GPS
position, it's hardly an endorsement of traditional methods! That's one reason why
I think it's important to get a handle on the variability of refraction and
its effect on these methods.
