9.3.5 Speed Vector Control

The vessel motion in Speed Vector mode is shown in Figure 9.11.
First set the value for the SPEED VECTOR parameter in the JST page.
If you select Joystick, you will use the joystick for setting the longitudinal and lateral vessel's component speed
setpoints. To activate this mode, press the speed VECT softkey in the POS panel. In the HDG panel, press the AUTO
or MANUAL softkey. The controller will be trying to move the vessel with the component speeds accordingly to the
joystick position.
If you select Manual, you must set exact values for the longitudinal and lateral vessel's component speed setpoints.
To activate this mode, press the speed VECT softkey in the POS panel. A bar appears where you can enter the component
speed setpoints. The controller will be trying to move the vessel with the component speeds accordingly to the required
values. For the heading control, press the AUTO or MANUAL softkey in the HDG panel.
NOTE! The desired speed vector will not be provided if there would not be
enough available thrust (or power), or the demand is very big.
