4. HOW TO CUSTOMIZE YOUR NAVPILOT
4-2
4.1.2 Manual parameter setup
To setup the parameters, follow the procedure below.
Note: This procedure requires [Self Learning] to set to [OFF].
1. Open the menu.
2. Select [Manual Parameters]. The [Manual Parameters] menu appears.
3. Select [Weather]. The weather setting popup appears.
4. Set the [Weather] parameter as required. The setting range is 1° to 10° and the
default setting is 1°.
When the sea is rough, the boat's heading fluctuates to port and starboard. If the
rudder is driven very often to maintain the set course, the helm mechanism may
wear out. To prevent this, the weather adjustment makes the NAVpilot insensitive
to minute course deviations.
The illustration below shows boat's track lines with weather setting 3° and 7°.
When 7° is set, for example, the rudder is not driven until the course deviation ex-
ceeds 7°. Increasing the setting reduces activation of the steering gear, however
the boat tends to zigzag. When the sea is calm, set a smaller value.
5. Select [Rudder Gain]. The rudder gain setting popup appears.
6. Set the rudder gain (sensitivity). The setting range is 1 to 20 and the default is 3.
When the boat's heading deviates from the set course, the NAVpilot adjusts the
rudder to correct it. The rudder angle (number of degrees) which is steered
against every degree of course deviation is known as the rudder gain.
