This setting is used for adjusting the autopilot's reponse on varies sea conditions.
The weather value sets the desired accuracy of the vesse l steering. A high
weather setting will cause the vessel to steer very accurately but may cause
excessive use of the steering.
In good weather, set this control to a high value, but ensure that the drive arrows
display on ship's heading field would not flickering continuously. This will give
the straightest possible course.
In poor weather, reduce this setting to prevent over-working the steering.
1.5.2 Rudder Control (Rudder Ratio)
This setting is used to determine the amount of rudder that the vessel requires
for steering (actually, the amount of rudder angle applied for a given angle
off course).
The centre position is usually suitable for most vessels, but also should depends
on the vessel's steering be sensitive or slow, adjustment maybe required.
In general, an agile vessel with a relatively large rudder or very small keel will
require a small rudder setting. A large, slow vessel may require a high value
for the rudder ratio.
