Minimal power heading
Minimal power heading is the estimated value of heading setpoint Minimal Power mode On/Off. The vessel heading
is controlled so as to minimize the power used by the thrusters (usually the vessel is brought as close to the resulting
weather force direction as possible).
By default the vessel is positioned with bow directed against the environment disturbance, but the operator can change
it to the stern against the disturbance.
In case the sector parameter is ON, the vessel turns as mentioned above but the bow will stay inside the preset sector.
This function operates in
Auto Position
and
Hold Area
(if available) modes.
The function is activated by the “Min Power” softkey. After preesing the softkey a dialog (10.10) appears.

For the positioning “Stern”, the settings dialog looks like represented on the figure 10.11
When the Min Power function is on the holding sector is displayed in the Map window (10.12).
In case the sector parameter is OFF, the sector value is 360
∘
and setting dialog reduces for the kind of figure 10.13
This function is optional.
For switching the function off (emergency or ordinary) select another heading control mode.
