These are the raw data from our cruises. GPS coordinates marked on the map to show the actual tracks (for those where ports are just not enough.)

It is interesting to note that the tracks for similar voyages are not identical, but very similar. I asked a Captain at one of the Meet & Greet events if there was a defined route (like air routes) and he said a Captain could use any route that he chose as long as the ship arrived on time, but currents and prevailing winds made the routes fairly predictable.
