...and this is an"Arkas" brain* The Decca "Arkas" is the only autopilot that thinks. It is programmed to automatically steer your vessel, light or loaded, in any sea state, in any wind force. It gives you extra speed and saves fuel by using fewer rudder movements. It also gives you precise elec-tronic steering under any maneuver. * The control panel shown above enables you to set the pilot for your vessel regardless of its size or steering gear. THIS IS HOW THE "ARKAS" DOES IT: 1. DAMPING CONTROL. In heavy weath-er this imposes a time delay, in sec-onds, on the autopilot. 2. ALARM LIMIT (Screwdriver setting). Set to give off-course alarm, gyro or power failure. 3. PERMANENT HELM CONTROL. MAN-UAL/AUTO. In 'Manual' it sets the amount of 'Weather Helm'. When 'Auto' is selected the ARKAS senses the cor-rect amount needed and sets it auto-matically. 4. RUDDER & COUNTER RUDDER CON-TROLS are set to adjust amount of 'Rudder' and 'Counter Rudder' to suit the vessel's load condition. 5. RUDDER LIMIT (ON/OFF). A variable control which sets a limit in actual degrees on the amount of rudder used by the autopilot. Provides controlled 'rate turns' when altering course. 6. SHEERING CONTROL. This is a sensi-tivity control that sets the amount of permitted yaw in actual degrees. 7. RUDDER ANTI-HUNT SCREW. Pro-vides an electronic adjustment to compensate for rudder overshoot. 8. WHEEL DEAD-BAND SCREW. Adjusts the sensitivity of the manual steering when ARKAS electric 'Follow-up' is installed. 9. The 'Rudder Multiplier' and 'Time Constant' controls are screwdriver settings set by the technician on in-stallation to bring the autopilot in ac-cordance with ship's characteristics.
