Chapter 2: Operating the SportPilot

Adjusting autopilot gain

The autopilot gain setting determines the amount of rudder the pilot
applies during course change. Autopilot gain is relative to the speed
of your boat.There are five available gain settings on the SportPilot:
•
•
•
Setting the gain for your boat
WARNING:
It is vital that the autopilot gain control is set correctly – an
incorrect setting will lead to poor steering performance and can
produce violent course changes at high speed.
The ideal gain setting for one boat may not be ideal for another, so
finding the correct setting for your boat will be down to
experimentation and experience. The following HI and LO setting
details are general guidelines only.
HI gains
Generally, low boat speeds require a medium to HI setting to provide
better course keeping.
WARNING:
This setting is not recommended for high speeds as it may cause
some instability and, therefore, could be dangerous.
LO gains
Most high speed boats will require a medium to LO setting. This
provides the greatest stability.
