Autopilots The first self-steering gear was introduced in the 1920's to control model yachts but it was not until 1948 that the principle was applied to full scale yachts. Standing at the helm for lengthy periods, monitoring instruments and keeping a good look out can be very tiring. An autopilot relieves the helmsman from steering the correct course leaving him free to maintain a proper watch. The autopilot can be set to either steer a compass course or a course relative to the wind. A fluxgate compass or electronic wind indicator feeds information to a microprocessor which then makes the necessary rudder movements to return the vessel to it's required course. The mechanical power is applied to the rudder by either electric linear activators, hydraulic pumps or rotary drives. GPS/Chart plotters can be used to input navigational instructions to the autopilot.
Battery Chargers will keep batteries fully charged thereby extending their working life.
Chart Plotters Typically a chart plotter consists of an an
