To see where this is, start from the picture showing Dakar as the westernmost tip of Africa, and zoom in.
Thus we can fine tune the departure point we guessed in an earlier article, but that does not change any of the rest of those early notes.
As I understand, the boat is now on the ship SANTA GIORGINA, which is, as I write, headed into the port of Gibralter, to arrive before midnight, tonight. After that stop, it must turn around and go straight on down to Dakar, I would guess. Dakar is about 1600 nmi from its stop in ALGECIRAS, and the ship cruises in the ocean at about 14-15 kts, which will taken them about 4 - 5 days, so we are right at the 13th. You can use the above link to watch the boat on the ship come down the coast of Africa.
So standing somewhere near Martin Luther King Blvd. in Dakar near Martin Luther King Day here the local folks in Dakar will hear Jordan's famous conch signal saying good by. Below is his signal saying goodby to Starpath at our last meeting, with Greg and Pat in the background.
So first rough estimates: leave by Martin Luther King Day, arrive by the Vernal Equinox.
Update added on Jan 24, to follow though on the conch. Here is the conch going off at the start with a neat video attached.
