A Raymarine chartplotter. A chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart (ENC).. 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 (AIS) or other sensors.
Charts are maps of the areas to be navigated with details specific to the marine environment. Computing aids: used in the necessary mathematical calculations. Today electronic computers or calculators are used. Other traditional aids used included tables (trigonometric, logarithms, etc.) and slide rules.
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...

The way in which the Yeoman plotter combines speedy GPS position fixing with a paper chart is cited as a benefit for two principal reasons. The first is one of safety and reliability - even the best marine electronics fail from time to time, and if the boat's electronic instruments should cease to work then a recent pencil plot on a paper chart becomes extremely valuable.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
Therefore, the majority of these types of devices are either water resistant or waterproof. Marine electronics devices include chartplotter, marine VHF radio, autopilot and self-steering gear, fishfinder and sonar, marine radar, satellite navigation device, fibre optic gyrocompass, satellite television, and marine fuel management.
