    There are a number of parameters used in the steering algorithms, collectively referred to as “Steering Parameters.” The P4 Autopilot system has been tested on a wide variety of boats, of different types and sizes. The default settings for the Steering Parameters are average values derived from that testing, and provide a good starting place for most boats.
