Click the gear icon, then select Profile to access the detailed steering behavior settings. For fine-tuning with visual feedback, choose Tuning.
Working with Profiles You can create and select profiles, with full control over all settings that influence steering behavior.
Default Profile At first use, only the "default" profile is available. The settings of this default profile cannot be changed.
Creating a New Profile
Click the plus icon (+) in the top right corner
Enter a name for the new profile
Click "Duplicate" to create the profile
The new profile will be activated immediately and is now fully customizable.
By clicking on the profile name, a menu will open where you can select and activate the desired profile. This can also be done via the menu on the ControlHead.
Adjusting Steering Behavior (P, D, DD, FF) The easiest way to fine-tune the autopilot's steering behavior is by adjusting the P, D, and DD parameters. For a more in-depth explanation of all tuning options, refer to the Tuning Gains page.
P – Aggressiveness The P parameter controls how aggressively the autopilot corrects the heading. A higher P value means the autopilot will react faster and more forcefully to heading deviations.
Note: If set too high, this may cause overshooting or instability.
D and DD – Damping The D and DD parameters determine how much the autopilot dampens its steering response. When increasing P, the boat will turn more quickly, but may overshoot the desired course. To counter this:
Increase D and DD along with P
This adds more counter-steering and reduces overshoot
On the other hand:
If the desired heading is not reached, or the autopilot counter-steers too early, then D and DD may be set too high — reduce them gradually.
FF – Turn Rate During Course Change The FF parameter defines how quickly the boat turns when changing to a new heading (e.g. in Auto mode).
Higher FF = faster turn to the new heading
Lower FF = slower, smoother course adjustment
tack.angle – Tack Angle (in degrees):
Set the angle by which the vessel turns during a tack maneuver when sailing on compass or GPS heading.
When sailing on wind angle, the autopilot automatically switches to the opposite tack.
tack.delay – Tack Delay:
Defines the delay between activating the tack function and the actual start of the maneuver.
This allows time for any manual actions before the tack begins.
tack.rate – Turn Rate During Tack:
Controls the speed at which the vessel turns during a tack.
A lower value results in a slower, more gradual turn.
tack.threshold – Threshold for End of Tack:
Set this value as high as possible.
If the vessel overshoots the target heading after the tack, reduce this value.
max_slew_slow / speed – Acceleration and Deceleration:
These values define how quickly the drive accelerates and slows down.
Lower values create smoother motion, reducing abrupt starts and stops.
Note: slow must not be set lower than speed.
period – Minimum Correction Duration:
Specifies the minimum duration of a correction movement.
Lower values enable quicker reactions to small heading deviations.
speed.max / speed.min – Maximum and Minimum Drive Speed:
speed.max sets the maximum drive speed.
Lowering this value can help limit movement intensity.
speed.min sets the minimum drive speed.
Note: With our drive, speed.min typically has little or no noticeable effect.
Also, max must not be set lower than min.
