Power boats
On power boats the automatic selection of HI or LO is
determined solely by the speed of the boat as shown in
the diagram above.
Sailboats
When 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
