Thanks to all. This has gotten me going in a very useful direction. I have looked at the various options and am starting with the information from Natural Earth Data. I am entering the ship's location log into Numbers (Mac OS spreadsheet) then importing into qgis. I will also try to export the vector layer as KML data and import that into Google Earth. I have tried tests and the paths show up on both applications -- qgis and Google Earth.
This is really cool.
