Note: Wind data and current data require appropriate sensors. The depth data requires
an adequate echo-sounding equipment. 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
compensating for own ship’s speed and orientation. 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 while T denotes “relative to True North” in the case of
EBLs and target ship vectors.
