2.9 Automatic control of steering parameters
The AP25 provides two different sets of steering parameters for
controlling the response of the boat at different speeds or wind
directions while in AUTO, NAV or WIND modes.
Power boat
The AP25 selects the LO (response) steering parameters when
engaging an automatic mode from STBY provided there is no
speed input. This is a safety feature. When entering an automatic
mode at low speed, the steering parameters may be changed to
HI automatically by input data from a speed log or a GPS
navigator, or manually.
The speed at which the AP25 automatically changes from LO to
HI parameters (or opposite) is determined by the "Transition
Speed" set in the Installation Setup Menu (Sea trial). See
diagram below.
