- Which chart is the right one for my chart plotter? -
Digital nautical charts are usually so-called vector charts, which means that chart sections can be enlarged or reduced and detailed information is displayed depending on the zoom level. The best known manufacturers of electronic nautical charts are Navionics and C-Map. Both manufacturers use different types of memory cards and different software systems. Not every card fits every chartplotter. Get an overview of the different sea charts.
Electronic sea charts are available in 4 or 6 different memory card formats.
1. Compact Flash charts (CF) from Navionics
2. Micro-SD / SD sea charts from Navionics
3. C-Card sea charts from C-MAP
4. Micro-SD / SD sea charts from C-Map
While the Navionics Compact Flash and C-MAP charts are used in older chart plotters, modern multifunction displays usually use micro-SD cards to display electronic charts.
Depending on the manufacturer of your chartplotter, different chart systems are supported, although Navionics nautical chart support has become standard with many manufacturers. Please note that there may be differences in compatibility depending on the plotter model. In general, the following compatibilities apply:
Raymarine chartplotters support Navionics nautical charts and C-MAP 4D sec charts.
Navico chart plotters, i.e. Simrad, B&G and Lowrance chart plotters, support Navionics nautical charts and C-MAP N+ charts.
Only Garmin blueChart charts are supported by Garmin chartplotters.
