Years ago I developed the pictured "Nav-A-Form"
. as a help in putting down all those figures and notes when taking sights, bearings, compass
corrections, tide & current
data, Determination of L.A. noon etc. as shown on the two illustrations. I placed it all on a 13"X14" ( same size as a position plotting sheet) plastic laminate that the navigator could pencil in figures that could be later be erased. One side has a graph whereby one can plot a string of sights and determine which one or two is good for reduction. At the time I thought it was a good idea but along came Loran
and GPS and interest in a laborious calculations too much trouble.
But I had made up numerous
which I still have.
So, is their still an interest in such an item for the navigator today ? Would it be worthwhile to try to market it again ? I checked to see if it would fit in to any available envelope ( cost alone about 3 bucks ) then the cost of shipping
...etc. Or just
An Ole Salt

Thanks for any suggestions.
