Interceptor Steering
Operators can experience signicant power loss when steering the vessel. The power losses result in higher fuel
consumption and speed loss during course corrections. Interceptor Steering equals faster response to a steering
command, getting a straighter course, improved fuel economy, and less wear of the water jet steering gear.
The steering force typically corresponds to a bucket deection of between 5 and 15 degrees. For larger steering
commands, the water jet buckets will start to deect, and the interceptors will contribute with increased steering
force at high speeds.
Interceptor Steering is usually setup to be controlled by an external system. For more information and instructions
on how to set the interceptor steering curve, see Setup Manual.
STANDBY
When interceptor steering is not requested by the external system.
STEERING OFF
When interceptor steering is requested by the external system but because for
some reason, the interceptor steering function is not working properly.
NOTE!
Without the following, the interceptor steering function will not work properly:
● Make sure there is a GPS signal.
● Make sure that the Rudder Input Signal Calibration is complete.
● Make sure that the servos are correctly installed and that there are no
alarms regarding the steering servos.
STEERING ON
The steering bar in the control panel will show the position of the steering
interceptors.
BACKUP STEERING
If the operator is not able to steer the vessel using the external steering system,
the interceptors can provide steering force.
1. Go to MENU/INTERCEPTOR STEERING.
2. Tick the BACKUP STEERING box.
3. Go back to the main screen and use the LIST function keys to steer the
vessel.
NOTE!
● When Backup Steering is activated, the operator will not be able to
manually change the list angles.
● The steering force is zero when the speed is below ve knots.
