Note: Wind data current data require the

quires an adequate echo-sounding equip-
ment. The echogram shows the last 30
minutes of depths along the ship's track.
Wind vector shows a direction from which
the wind blows in, relative to own ship
heading, and labeled T*. Wind velocity is
a true wind speed as a result of compen-
sating for own ship's speed and orienta-
tion. Ocean current (tide) is the direction
to which the current is flowing away from
os position, relative to north.
*T in this case means a true value mean-
while T denotes "relative to True North"
in the case of EBLs and target ship vec-
tors.
