 devices. Therefore the majority of these types of devices are either water resistant or waterproof.

The term marine electronics is used for areas such as
  • Ship
    Ship
    Since the end of the age of sail a ship has been any large buoyant marine vessel. Ships are generally distinguished from boats based on size and cargo or passenger capacity. Ships are used on lakes, seas, and rivers for a variety of activities, such as the transport of people or goods, fishing,...

  • Yacht
    Yacht
    A yacht is a recreational boat or ship. The term originated from the Dutch Jacht meaning "hunt". It was originally defined as a light fast sailing vessel used by the Dutch navy to pursue pirates and other transgressors around and into the shallow waters of the Low Countries...



Marine electronics devices are
  • Chartplotter
    Chartplotter
    A Chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart . The chartplotter displays the ENC along with the position, heading and speed of the ship, and may display additional information from radar, automatic information systems or other...

  • Marine VHF radio
    Marine VHF radio
    Marine VHF radio is installed on all large ships and most seagoing small craft. It is used for a wide variety of purposes, including summoning rescue services and communicating with harbours, locks, bridges and marinas, and operates in the VHF frequency range, between 156 to 174 MHz...

  • Autopilot
    Autopilot
    An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. An autopilot can refer specifically to aircraft, self-steering gear for boats, or auto guidance of space craft and missiles...

    /Self-steering gear
    Self-steering gear
    Self-steering gear is equipment used on ships and boats to maintain a chosen course without constant human action. It is also known by several other terms, such as autopilot and autohelm...

  • Fishfinder
    Fishfinder
    A fishfinder is an instrument used to locate fish underwater by detecting reflected pulses of sound energy, as in SONAR. A modern fishfinder displays measurements of reflected sound on a graphical display, allowing an operator to interpret information to locate schools of fish, underwater debris,...

    Sonar is a technique that uses sound propagation to navigate, communicate with or detect other vessels...

  • Radar
    Radar
    Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

  • GPS
  • Electronic compass
    Compass
    A compass is a navigational instrument that shows directions in a frame of reference that is stationary relative to the surface of the earth. The frame of reference defines the four cardinal directions – north, south, east, and west. Intermediate directions are also defined...
