To initiate a DCT turn:

Ensure that you have depth reading on the panel or on a
separate depth instrument

Steer the boat to the depth you want to track, and in the
direction of the depth contour

Activate AUTO mode, then select depth contour tracking while
monitoring the depth reading

Select the port or starboard option in the turn dialog to initiate
the depth contour steering to follow the bottom sloping to
starboard or to port

Port option

(depth decreases to port)

Starboard option

(depth decreases to starboard)

Turn variables:

- 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
