John,
I agree with your opinion of the N(x) table and am surprised that it has never been discussed on NavList. Maybe with enough 2 cents we can reach a dollar!
Stan

Hi Stan,
I bought the plastic emergency cel nav card by David Burch and I loved it. The N(x) table was easy to use, compact, and accurate for life boat or emergency use. My quick kit had that and a Davis Mark 3 along with other stuff. Now, I live in Nebraska and do not own a boat but like a lot of us on NavList I do practice shots in my backyard and when I travel.
Untill the Hanno, et all Haversine method the N(x) was my pen and paper sight reduction. I do belive that it deserved more use than it seems to have. Better than the very long method in the Nav Almanac or even the S tables.
Just my 2 cents.
John H.
