OPERATION OF THE CPT AUTOPILOT The CPT is an extra crew member to man the wheel, day or night, rain or shine. It is amazing to take your hands off the wheel and experience the freedom the CPT provides. WARNING!

CPT Operation Turn power on with Rudder control. Wait at least 1 minute for pilot to warm up before using. To Steer with Autopilot: Hold boat on desired heading 30 seconds. Engage Clutch. Flip toggle-switch up to Hold Heading. Fine tune Rudder and Deadband as needed. To Hand steer: Flip toggle-switch down to Standby and Disengage Clutch * In an emergency, the wheel can be forced to overpower the clutch and shear the shear-pins...
OVERVIEW OF AUTOPILOT OPERATION The rudder control and deadband control must be set properly for the CPT to hold heading. Tack angles are approximate and will vary from boat to boat based on the magnetic environment and deadband setting, you will have to see which angle works best for your boat.
Rudder Control The Rudder control turns the autopilot on, and determines how far the boat’s wheel (and rudder) turns when a heading correction is needed; the response is the same for both port and starboard corrections and will not work well with play in the steering system. Low settings result in smaller wheel corrections, higher settings in larger wheel corrections.
Setting the Magnetic Reference Setting the magnetic reference aligns the autopilot compass to the local magnetic inclination (dip angle). The autopilot comes from the factory set for the magnetic field inclination in California. If you are located significantly farther north or south, the magnetic reference should be set again on location.
SAIL TRIM Even the best autopilot can be crippled by poor boat trim, and the rudder and deadband settings effect how accurately the boat holds the heading. The boat must be balanced on all points of sail and in all wind conditions for proper CPT operation. This means that through the skipper's selection of sails, trim and heading, the boat should tend to maintain a stable course without a significant amount of weather or lee helm.
APPENDIX Dockside Checkout The CPT is run for 24 hours at the factory before final testing, and the motor rotation direction has been preset for your type of installation. It should steer your boat easily and require not more than an hour or so of experimentation to become familiar with it.

* Rudder control too high: If the CPT steers too far to port and then too far to starboard, lower the Rudder setting. If the wheel turns too far when the CPT makes corrections, the boat will over-steer; lower Rudder just enough to prevent over steering. Set the rudder control as high as possible, but not so high that it over steers.

Motor turns the wheel the Wrong Direction The direction the motor rotates must be set for the wheel to turn the correct direction; it has been preset for your installation at the factory.

Poor Power Connections and Voltage Drop Just checking for 12v at the line is not adequate; voltage drop will only show while pilot motor runs and draws current. The small drive pulley may barely turn or vibrate with excessive voltage drop in power line. With the belt removed you should not be able to stop the small drive pulley with your hand.
