What is Response?

This sets the S1000 response level setting. The response level controls the relationship between course keeping accuracy and the amount of helm/ drive activity. Range is from 1 to 9.

level 1 minimizes the amount of pilot activity. This conserves power, but may compromise short-term course-keeping accuracy

levels 4 to 6 should give good course keeping with crisp, well controlled turns under normal operating conditions

level 9 gives the tightest course keeping and greatest rudder activity (and power consumption). This can lead to a rough passage in open waters as the pilot may ‘fight’ the sea.

What is Auto Trim?

The AutoTrim setting determines the rate at which the S1000 applies ‘standing helm’ to correct for trim changes caused by varying wind loads on the superstructure.

The default AutoTrim is set during the autolearn process:

If you need to change the setting, increase the AutoTrim one level at a time and use the lowest acceptable value:

decrease the AutoTrim level if the S1000 gives unstable course keeping or producing a long ‘S’ in the wake.

increase the AutoTrim level if the S1000 reacts slowly to a heading change and hangs off course.
