ComNav 1101 Autopilot
Following Seas
When traveling with a following sea—the waves are approaching
your vessel from astern—speed relative to the water is reduced as
the vessel accelerates or surfs down the face of each wave. This
has the same effect on steering performances as traveling at slow
speed. To improve Autopilot performance in a following sea,
increase your rudder setting and counter rudder setting.
Current, Tide and Wind
If you are traveling with a current, tide or wind at an angle to your
desired course, the vessel will be pushed off course consistently in
the same direction. After a period of time, the Autopilot will build up
“trim” to deal with the cross tide, current or wind. You do not have
make any adjustments as this is an automatic feature. If you have
an external Rudder Angle Indicator, you will notice that the rudder
will be offset from its normal center position. The Autopilot
removes all trim each time it receives a new commanded course.
