Nautical Charts
The most essential tool available to a boater is a navigational chart.
A navigational chart displays the marine environment similar to a
road map and is important for safe navigation. They often contain
information on buoys and beacons, lighthouses, radio and weather stations,
shipping channels, and restricted areas. Also water depths are recorded
as soundings, in meters, feet or fathoms. Near shore depths are shown
by contours and layered tints. Physical features such as shorelines,
shallows, reefs submerged rocks, shipwrecks, kelp beds, ocean bottom
sediments, are all shown in detail. |
