Vessels more than 10 nautical miles from shore must carry a chart or map of the waters they’re navigating.
Charts and maps:
• must be suitable for the navigation purpose
• help the skipper to plot a course or destination
• identify the current location, the depth of water, hidden reefs, islands and other navigation features
• show detail such as the beacons and navigation markers to harbor and channel entrances.
So, always use:
• largest scale charts because more detail is shown, reducing the chance of error
• up-to-date chart editions.
A GPS will not satisfy the legal requirement to carry a chart or map of the area that a vessel is operating.
