    The occasion below was measured while going south with the current only a
    couple of miles off the coast, where the effects usually tend to be less.
    Sometimes a counter-current is found there that has swept around the
    northern side of a cape further to the south and then runs some way to the
    north along the coast, at a weaker rate than the main current. For this
    reason sailors - and huge ships sometimes, unfortunately - tend to hug the
    coast going north.
    Going south its the opposite story. The current tends to be strongest out
    along the edge of the continental shelf, at about 200 metres of depth, the
    old 100 fathom line. Just to round off my personal evidence for the EAC's
    unpredictability, once we were sailing south for about 600 nm along the
    coast, and sat out there, about 10 nm from shore, in the hope of the current
    wafting us home, as there was little wind. Out of luck, the current seemed
    to have gone to the same place as the wind, almost entirely missing.
