When navigating narrow channels, charts in the largest scale available should always be used as these give the best and most detailed information about the waters. Electronic Navigational Charts (ENC) are vector data sets that support all types of marine navigation. Originally designed for large commercial vessels using a sophisticated navigational computer called an Electronic Chart Display and Information System (ECDIS), ENCs are now also being used on simpler electronic chart systems and “chart plotters” on many types of ships and by recreational boaters. The selected stars for navigation are often used for sextant observations. Fifty-eight selected navigational stars are given a special status in the field of celestial navigation.
