reduce battery use while still providing a good average course. A deadband of "5" will allow the boat to range

about 10° to port or starboard of the target heading; the pilot will make a correction if the boat strays more than

10° to port or starboard. When the boat's heading is within the deadband range, small heading adjustments made

with the 1° button will change the target heading but not take immediate effect until the boat's heading is outside

the deadband range. The lowest deadband setting allows the boat to range about 1° to port or starboard of the

target heading, depending on the boat's response to the rudder.

Rhythmic CPT steering corrections, in time with the roll of the boat, indicate that the deadband is too low. The

deadband should be slightly raised to avoid constant correction. A low deadband does not always mean that the

boat will maintain a straighter course; it can cause the pilot to over steer if the rudder setting is too high. In

rougher seas, the deadband should be higher to avoid constant corrections. A lower deadband setting is generally

beneficial when sailing downwind or in flat water. Lower deadband settings cause higher sensitivity to heading

changes; higher deadband settings cause lower sensitivity to heading changes.

Most of the CPT's steering action should be periodic corrections. Raise the deadband a bit to avoid excessive

battery drain and wear on the CPT.

Summary:

The Rudder determines how far the wheel should be turned when corrections are needed; the

Deadband determines when a correction is needed or the "sensitivity" to heading changes & seas.

H. Reversing Rotation of the wheel

: (This is preset for your installation at the factory)

When reverse-mounting the drivebox to the helm, the rotation of the wheel & drive-pulley must be reversed

so the wheel will turn the correct direction. This is preset at the factory for your installation but can be

easily changed.

1. Turn CPT OFF. While off, push & hold down the Starboard 1° & 10̈ ° buttons and the Port 10° button;

hold all three buttons down at the same time.

2. While holding the buttons down, turn the pilot on, then after 5 seonds release the buttons.

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 and trim, the boat should tend to maintain a stable course

without a significant amount of weather or lee helm. Reef & trim when wind and sea conditions increase .

When sailing, the boat should maintain adequate speed for effective rudder control; it must make enough

headway for steering to be effective. When wind and seas increase, and especially when running downwind,

quick rudder response becomes important; lowering the deadband and slightly raising the rudder control helps

with full keels, and increasing vessel speed or falling off will lessen the effect of following seas. Fin keels may

benefit from lowering the rudder setting due to increased speed & rudder efficiency. Always be aware of the

relative wind angle, and keep the boat on a course to prevent an accidental gibe. If the boat is in danger of
