    I have attached a portion of the January Pilot Chart of the South
    Pacific Ocean published by the Defense Mapping Agency. Until I looked at
    this chart I had no idea that currents in the South Pacific could be so
    strong. The green arrows show the current  direction and speed in knots.
    For example, the current shown passing the southern end of New Zealand
    is 10 to 20 knots! And in the Gilberts it shows up to 30 knots! How do
    ships manage to maneuver against such strong currents?
