• if rudder gain is too high, courses change will result in a distinct
overshoot (A)
• if rudder gain is too low, the boat will feel sluggish – it will take a
long time to make the turn and there will be no overshoot (B)
Note: See page 71 for a full explanation of rudder gain and how to
adjust it correctly.
If necessary, you can make a temporary change to rudder gain
as follows:
1. Press the -1 and +1 keys together for 1 second to display the
rudder gain (RUDD GAIN) screen:
•
if you have set up the RUDD GAIN screen as a default data page
(see page 81) you can also access it by pressing disp and then
scrolling through the data pages.
2. Press -1 or +1 to change the rudder gain.
3. Press disp or wait for 5 seconds to return to the previous display.
Note: You will lose these temporary changes to rudder gain
whenever the system is powered off. You can make permanent
adjustments in User or Dealer Calibration (see page 91).
WARNINGS:
1. You must set rudder gain correctly on planing craft. Incorrect
rudder gain will lead to poor steering performance and can be
dangerous at high speeds.
2. If you increase the rudder gain setting on a Type 150G/400G
autopilot, you must also increase the counter rudder setting.
