Rudder deadband
This parameter is used to prevent the rudder from hunting. The
reading is obtained from the Rudder test which optimizes the
deadband to the speed of the boat and the pressure on the rudder.
If the auto-setting does not perform properly due to high inertia
from the wheel or a loose steering gear, it can be adjusted manually.
Find the lowest possible value that will prevent the rudder from
continuous hunting. A wide deadband causes inaccurate steering.
Ú Note:
The rudder deadband setting is not available when the
autopilot is configured for Virtual Rudder Feedback.
Seatrials
A seatrial can only be performed if the dockside settings are
completed and confirmed. The seatrial must always be performed in
open waters at a safe distance from other traffic.
Ú Note:
A dedicated physical standby key should be available
during the seatrial. This can be the standby key on the autopilot
control head, on an autopilot remote controller or separate
physical standby key. You can switch the autopilot to standby
mode and take manual control of the boat at any time during
the seatrial by pressing the standby key.
The following seatrial calibration should be done:
• Compass calibration; used to automatically compensate for on-
board magnetic interference
• Compass offset adjustment, used to compensate for a fixed offset
in the final heading readout
• Wind vane offset is to compensate for a wind vane that is not
mounted facing in exactly the same direction as the bow of the
vessel (dead ahead)
• Boat speed calibration
• Transition speed setting (the speed at which you want to change
the set of steering parameters). This setting is not available for
NAC-1 autopilot computers.
• Automatic tuning of the steering parameters. This setting is not
available for NAC-1 autopilot computers.
• Setting the seastate filter. This setting is not available for NAC-1
autopilot computers.
