Hi Brian:

My favorites are the time sight (haversine equation) solution for longitude combined with ex-meridians/polaris and the noon sun for latitude. (no plotting required)

I use Norie's nautical tables for all computational data needed.

I also use Norie's ABC tables (same book) for azimuth when I am inclined to lay down an LOP.

I am familiar with many of the other methods you mention, but find the above to be the most intriguing (widely used in the 19h and early 20th centuries) , and satisfy my parameters for a choice below.

1. Non electronic and based on accurate sextant measurements and an accurate chronometer.
2. As little plotting as possible.
3. As little tedious mathematics (prone to mistakes) as possible.
4. As few books as possible.
5. The best accuracy possible given 1 through 4.

Cheers

Doug
