A majority of cargo ships, tankers, passenger ships, and mega yachts use electronic chart display and information systems (ECDISs). Navigating with ECDIS is fundamentally different from navigating with paper charts. At present, the training program being conducted follows the "IMO Model Course 1.27 (2012 Edition), which is the version certified by the 2012 IMO/STCW subcommittee". Basic ECDIS requirements are set by the IMO, but because there are many manufacturers producing ECDIS models, which operate quite differently and require type-specific training, navigators must make sure that they identify and work with the specific limitations of each ECDIS they rely upon. Study now. An ECDIS system includes not only the visualization of all paper chart information on a computer screen, but also provides a wide range of other data required for navigational purposes As goes with all cases, firstly, it is important to identify the risks and not to show over-reliance on this new technology.
