2.9Automatic control of steering parameters

The autopilot 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 autopilot 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 autopilot 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.
