Power boats
On power bo
ats the automatic selection of HI or LO is
determined solely by the speed of the boat as shown in
the diagram above.
Sailboats
W
hen sailing in WIND mode, the parameter set is
determined by the speed of the boat and the direction of
the wind as per below.
So if you loose too much speed e.g. when tacking, the
parameters will change to HI to gain sufficient rudder
response. This should be observed when setting the
transition speed on sailboats. See also Wind response on
page 15.
Response adjust
The Autotune function in the AP24 is so refined that the
majority of boats will need no further adjustments of the
steering parameters. On some boats, however, or at
particular sea conditions a fine tuning of the steering
parameters may improve the performance of the
autopilot.
The Response control allows you to make this fine tuning
for each of the two (HI/LO) parameter sets. The response
can be set to nine levels. Level 4 is default with
