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.
