Brian,
If I remember correctly, this is the symbol for a rotating current. The
times and length of the vector (arrows) represents the time as well as the
direction and strength of the current. You can determine the direction
(set) by looking at the nearest compass rose. The length is the strength or
more properly drift rate (knots per hour) of the current. Take the distance
and look at the nearest latitude scale.
Going to Greece - get the local charts and be careful to set your GPS to the
local chart datum and world model. There are enough differences to make
life interesting.
I have a BMP file of the Southern Cycades that I can email you if you are
interested.
