34 SmartPilot Commissioning Guide

Manual set-up: Non-G Systems

If you have a Non-G system you need to manually adjust the rudder gain,

counter rudder and AutoTrim settings, based on your observations of the

boat’s performance under SmartPilot control.

Adjust these settings when motoring your boat at cruising speed. On sail

boats, repeat if necessary under sail to optimize the SmartPilot.

Checking SmartPilot operation

Before manually adjusting any of these settings, familiarize yourself with

basic SmartPilot operation:

1. Steer onto a compass heading and hold the course steady.

If necessary, steer the boat manually for a short time to check how the

boat steers.

2. Press auto to lock onto the current heading. The SmartPilot should hold

a constant heading in calm sea conditions.

3. Use the -1, +1, -10 and +10 keys or the rotary control to see how the

SmartPilot alters the course to port and starboard.

4. Press standby to return to manual steering.

Response level

The principal method of adjusting the performance of SmartPilot systems is

by changing the response level. This is the only user adjustment you should

need to make to the SmartPilot on a regular basis. This controls the

relationship between the SmartPilot’s course keeping accuracy and the

amount of helm/drive activity.

Whilst it is not necessary to set the response level at this stage, the testing of

other parameters requires the temporary adjustment of response settings.

Screen Text Options

RESPONSE 1 The SmartPilot will gradually ignore repetitive boat move-

ments and only react to true variations in course. This gives

the best compromise between power use and course keeping

RESPONSE 2 This setting provides tighter course keeping but will lead to

increased power consumption and drive unit activity

RESPONSE 3 This setting provides the tightest possible course keeping.
