Default Easiest Way to Get Lat/Lon Data from Paper to Plotter?

My late brother used to perform "complementary" engine work for a long-time charter captain out of west-central Florida, and when he retired, he handed my brother his numbers. My brother had always told me about them, but I never saw them. When he passed, I found them nestled away in the pages of a Chapman book on his boat.

They're typed on a couple of pieces of paper that look like they date back to the Santa Maria! The captain evidently refused to enter any of them in his electronics, so they remained on paper for goodness knows how long. Anyway, what's the best, most efficient way to get them entered into my MFD?

use Excel or a text editor program
to create a simple document
in to which you'll type in the data in columns:
with the top line the "field" - name, description, lat, long
with Excel, one column per field
with the text editor, separate each with a tab

when you've got them all in,
save the file as a .csv or .txt
and then upload to GPS Visualizer,
selecting the output to be "GPX"
GPS Visualizer

download the resulting file -
it will end in .gpx
which you can then copy to an SD or MicroSD -
whichever your plotter takes -
and use the plotter menu to import the waypoints
(the exact procedure varies by brand and model of course)

Most if not all recent units accept the 'generic' .gpx file format
If your's won't,
you can use another function of GPS Visualizer
https://www.gpsvisualizer.com/
to convert the .gpx to your brand's proprietary file type.

If they're that old are they lat/lon or LORAN?

It has both GPS and Loran coordinates.

Nah, I'm just smart enough to find and take advantage of free resources on the internet.

The real smart people are those that create software programs such as GPS Babel and GPS Visualizer
and webpages such as

What he meant to say, before using the gpx visualizer, is that we will need to see all the coordinates to determine the exact type of file to use. Best to just post pictures of them or better, just message them to me.

That’s what I had to do to get all my numbers from an old Raymarine unit to my new one 👍
