A typical plot of an ocean track is shown below using the default scale of 60 nmi per printed latitude parallel. The longitude scale is set up using the inserted diagram, after marking the central Lat on the Lon scale of the diagram.
This is a good fix, but we can't tell how good using the standard scale for the plots shown here. We can expand the standard scale by redefining the Lon diagram. Below is how it would change if we go from 60 nmi per parallel to 30 nmi per parallel.
At the time of the voyage, we chose 24º 39'N, 151º 16' W to plot from, and below is an image of the actual plotting sheet from that voyage, 37 year ago.
Hawaii by Sextant to review our Fit Slope Method in action along with our automated LOP advancement technique, which is required for best accuracy. This makes a set of 15 sights of four bodies an extended running fix over a 30 minute sight session to get equivalent sights at one time. Both yield notable improvements to the multiple sights analysis. In this sight session, Capella was the weakest with just one sight; the other three had at least 4 each.
Here is a short video discussion of the above process:
