CURRENT SAILING
Current sailing is an art
to determine course and speed, allowing effect of a predicted or
estimated current to make
sure that an intended track and an actual track are the same.
There are three types of
currents of interest to the navigator.:
Ocean current; a well
defined current over a size able ocean area.
Tidal current: one due
to tidal action, as in harbors, estuaries and coastal .
Wind current: affects an
area where wind is strong for twelve hours or more,
current does not flow in
wind direction.
Estimated Current
determined by check of known forces that make current effects.
Actual Current:
determined when actual position is available.
Set of a current is the
direction it flows.
Drift of a current is the
velocity .
