Turn variables

• Ref. depth: this is the reference depth for the DCT function. When

DCT is initiated the autopilot reads the current depth and set this

as the reference depth. The reference depth can be changed

when the function is running

• Depth gain: this parameter determines the ratio between

commanded rudder and the deviation from the selected depth

contour. The higher depth gain value the more rudder is applied.

If the value is too small it will take a long time to compensate for

drifting off the set depth contour, and the autopilot will fail to

keep the boat on the selected depth. If the value is set too high

the overshoot will increase and the steering will be unstable.

• CCA: the CCA is an angle that is added to or subtracted from the

set course. With this parameter you can make the boat yaw

around the reference depth with s movements. The larger the

CCA the bigger yawing will be allowed. If the CCA is set to zero

there is no S-ing.

Autopilot settings

The Autopilot settings dialog depends on which autopilot

computer that is connected to the system. If more than one

autopilot is connected, the Autopilot settings dialog shows option

for the active autopilot.

Chart compass

Select to display a compass symbol around your boat on the chart

panel. The compass symbol is off when the cursor is active on the

panel.
