Autopilot

The first report of self-regulation in the 1920 years has set up to control model yachts but it was not until 1948 that the principle has been applied to full scale yachts. Standing at the top for long periods, monitoring instruments and keeping a good look out can be very tiring. An autopilot relieves the helmsman, the right course it could be free to control keep a proper lookout. The autopilot can be set to steer a compass course or a course by winds. A fluxgate compass or electronic weather vane feeds information to a microprocessor which then makes the necessary rudder movements of the ship on its return required courses. Mechanical power is applied the rudder by either electric linear actuators activators, hydraulic pumps or rotary discs. GPS / plotter can be used to input navigation instructions to the autopilot.

Chart Plotters Typically a plotter consists of an antenna, mounted high on the boat, using GPS signals and a display to either the station or track navigation of the ship rudder. The boat position is sent from the antenna to the display unit, further demonstrating graphically on the map. The table itself looks like the paper equivalent and show depth, land mass, navigational aids such as buoys and hazards in the form of wrecks and obstructions. The user can add waypoints to a map and zoom in and zoom out of the screen. card readers are connected to an autopilot drive and / or data to a GPS fish finder or radar. You can also use a laptop enabling complex passage planning to be done to remove from the boot interface, then entered the chart plotter after arriving at the boat.

Satellite Phones consist of an antenna, a modem and a normal mobile phone. They are characterized by a battery powered by Iridium. Their range is anywhere covered by the Inmarsat mini-M satellite. Voice, fax, e-mail and data can be transmitted.
