Spiral turn
Spiral-turn makes the vessel turn in a spiral with a decreasing or increasing radius. You set the
initial radius before the turn is initiated, and the change per turn during the turn. If the
change per turn is set to zero, the vessel turns in a circle. Negative values indicate decreasing
radius while positive values indicate increasing radius.
Zigzag turns
Steers the vessel in a zigzag pattern.
For navigating in a zigzag pattern, you set the initial heading change before the turn is
started.
During the turn you can alter the main heading, the heading change, and the leg distance.
Square turn
Makes the vessel automatically turn 90° after having travelled a defined leg distance.
At any time during the turn you can change the main heading and the distance of the leg
until the vessel makes a new 90° turn.
Lazy S-turn
Makes the vessel yaw around the main heading.
You set the selected heading change before the turn is started.
During the turn you can alter the main heading, the heading change and the turn radius
from within the turn dialog.
Depth contour tracking, DCT
TM
If the system has Echosounder input, the autopilot can be set to follow a depth contour.
Warning:
Do not use this feature unless the seabed is suitable. Do not use
it in rocky waters where the depth is varying significantly over a small area.
Use the following process to initiate DCT steering:
1.
Ensure that you have depth reading on the panel or on a separate depth instrument.
2.
Steer the boat to the depth you want to track, and in the direction of the depth contour.
3.
Activate
AUTO
mode, select depth contour steering and monitor the depth reading.
4.
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:
