Nautical charts are graphical representations of a boating trip.
Nautical charts used by maritime travelers are comparable to geographical maps used by land travelers. Because vast waters do not provide many “landmarks” such as route numbers and street names to help seafarers find their way, nautical charts must be used. Such charts include information about tides, water depth, distance and geography of nearby coasts, currents and hazard location. Historically, nautical charts were created painstakingly by hand through measurement, repeated trips and vetted research. Now, with the help of computers, software and the global positioning system, creating nautical charts is a more precise and efficient process.
Instructions
- 1
Obtain a software program such as Chart Navigator Pro, SeaClear, Trident or any other chart program you prefer. Install the program and familiarize yourself with its interface.
- 2
Plan the trip that will be depicted in your nautical chart. Identify where you will begin as well as your final destination. If the trip will take more than a day, identify safe points at which to dock or drop anchor.

- 3
Indicate within the software program each of these points in the order you will reach them. For most programs, this entails using the mouse to click on the location. Save your chart with an intuitive name for easy retrieval. The chart can be printed or accessed electronically if you intend to bring your computer aboard ship.
- 4
Examine the chart to ensure you will be traveling in safe and legal waters. Most chart programs will indicate areas that are off limits and adjust your route for you. However, you should be aware of the details of your route, such as water depth, bridge height, wildlife concerns and underwater geography.
