Rudder gain
Rudder gain controls the amount of rudder the pilot will apply to turn
onto a new heading.
A correctly set rudder gain will, for example, turn the boat crisply
onto the new heading with an overshoot of no more than 2° to 5° for a
40° course change. A high rudder gain setting will result in oversteer,
recognized as an overshoot of more than 5°.
A rudder gain level that is too low will result in understeer giving poor
steering performance.
WARNING:
It is most important that the rudder gain is correctly set on
planing craft. Incorrect adjustment will lead to poor steering
performance and is dangerous at high speeds.
The settings available are as follows:
•
Range = 1 to 13
•
Default:
•
High Speed = 5
•
Low Speed = 9
Counter rudder (rate) level
Counter rudder (rate) level determines the amount of rudder applied
to reduce the rate of turn. Level 9 applies the most counter rudder. The
settings available are as follows:
•
Range:
•
High Speed = 1 to 9
•
Low Speed = 0 to 9
•
Default:
•
High Speed = 7
•
Low Speed = 0
Rudder offset (Align rudder)
Rudder offset sets the control head to read zero degrees of rudder
when the helm is positioned amidships. The range available is:
•
Range = -7° to +7°
•
Default = 0
