WORKING PRINCIPLE When the boat moves away from the displayed course, the autopilot electronic computer sends current to the motor terminals or to the power pack electrovalve. Then, the cylinder will be supplied with oil and set in motion. As soon as the boat is back on the displayed course, the computer stops supplying the power pack and the cylinder stops moving. • MOTORBOATS EQUIPPED WITH HYDRAULIC STEERING © Manual pump @ Tubing ® Power pack ® By-pass valve ® Cylinder ® Tiller arm • SAILING BOATS EQUIPPED WITH WIRE ROPE STEERING © Manual steering ® Quadrant ® Linear cylinder © Rudder...

SELECTION OF THE SYSTEM • For boats equipped with a hydraulic steering, it will be necessary to determine: - The volume of the steering cylinder (take the biggest volume in case of a single rod cylinder) - Available voltage on board (12 VDC, 24 vDc, etc.) For planing or semi-planing hulls, the power pack will be selected in function of its flow rate so that the steering cylinder will run its complete stroke within 10 to 12 seconds. For displacement hulls, the power pack flow rate must enable the steering cylinder to run its complete stroke within 15 to 17 seconds. x 0.239 litre (239 cc) =...
