Electronic Chart System (ECS)

The MarinePlotter ". . . is an Electronic Chart System (ECS), which can be used to assist navigation, but does not meet IMO/SOLAS chart carriage requirements." An ECS is specified in ISO 19379 as follows: "ECS is a navigation information system that electronically displays vessel position and relevant nautical chart data and information from an ECS Database on a display screen, but does not meet all the IMO requirements for ECDIS and is not intended to satisfy the SOLAS Chapter V requirements to carry a navigational chart.
See source pdf (no longer available.)

"Where the vessel operates with ECS, the paper chart remains the official basis for navigation onboard. The vessel must retain and use a full folio of up to date paper charts onboard, regardless of the type of electronic charts used."
