How to read a nautical chart

When you’re out on the water, it’s important to be able to read a nautical chart. This will help you navigate safely and avoid any hazards. Here’s how to do it:

First, take a look at the legend. This will tell you what all the symbols on the chart mean. Once you know what they represent, you can start to interpret the information.

Look at the contour lines to get an idea of the depth of the water. The closer together the lines are, the shallower the water is. You’ll also want to pay attention to any shoals or sandbars that might be marked on the chart.

Next, take note of any buoys or other marks that indicate hazards. These will be shown as red triangles on the chart. It’s important to stay away from these areas.

Finally, use all this information to plot a safe course through the water. Make sure to avoid any shallow areas or hazards that could damage your boat. With a little practice, reading nautical charts will become second nature!


A green can-shaped buoy marks the location of a safe waterway. This type of buoy is used to mark the entrance to a channel or harbor. It is also used to mark the start of a race course.
