Be smart, use a chart

21 October 2010

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.
