First of all, let us explain what a nautical chart is and what it is for. A nautical chart is a detailed graphic representation of a coastal or maritime area, which includes important information about the waters in which it navigates, including water depth, location of hazards and underwater topography.
Why is it important to know how to make a nautical chart?
First of all, it must be clear that sailing without a nautical chart can be dangerous and even deadly. Without a nautical chart, a navigator is more likely to be confused about his or her position and destination, which can result in disorientation and navigation in dangerous waters.
Accidents, such as collisions with underwater obstacles or areas of shallow water, are also more likely to occur. In addition, sailing without a nautical chart can also result in penalties and fines from maritime authorities in many countries.
Here we will show you how to make a nautical chart in 6 simple steps to make your next boating trip safe and smooth:
1. Gather information about the coastal area
Before you start drawing your nautical chart, it is important that you gather the most recent and accurate information about the coastal area you wish to depict. This information may include the depth of the water, the position of reefs and shoals, and the location of potential navigational hazards.
You can obtain this information from a variety of sources, such as logbooks, sounding reports or, in some cases, from your own previous sailing experience.
2. Select the type of chart you want to make
There are several different types of nautical charts, each with its own focus and specific details. For example, some charts show only the most essential navigational information, while others include more detail about the topography and geography of the coastal area.
Decide what type of information is most important to you and select the type of chart that best suits your needs. But how do I know which type is best for me?
To know which type of nautical chart is best for you, it is important to consider your sailing needs and preferences. Here are some factors to consider when choosing a nautical chart:
- Purpose of navigation: Are you navigating in coastal waters or on the high seas? Are you navigating for recreation or for commercial purposes? The purpose of navigation will influence the type of nautical chart you need.
- Geographical location: Nautical charts are available for different regions and geographical areas, so it is important to choose one that covers the area in which you plan to sail.
- Level of detail: Nautical charts vary in their level of detail. Some may be very detailed and include information on water depth, location of hazards and underwater topography, while others may be simpler and show only basic information. Choose a chart that suits your navigational needs and is easy to read and understand.
- Format: Nautical charts are available in paper or electronic format. Choose a format that is convenient and easy for you to use, and that suits your navigational needs.
3. Gather all the necessary material
Before you start making your nautical chart, it is important that you have all the necessary materials at hand. Depending on whether you are making a digital or paper chart, you will need different instruments.
In the case of a paper chart, you will need a pencil, a ruler, a compass, drawing paper and a scale. The scale is essential to ensure that your chart is accurate and easy to read.
If you choose the digital chart, you will need an electronic device with GPS. This is more interactive and can be updated automatically with the use of different software.
4. Draw the nautical chart
Once you have collected the necessary information and gathered the necessary materials, you can start drawing your nautical chart. Start by drawing the coastline and important topographical features such as bays, headlands and inlets. Be sure to use a scale and your compass so that everything is accurate and proportionate.
Next, add information on water depth, including information gathered on sandbanks, reefs and potential navigational hazards. Use a variety of symbols and colours to make this information easy to identify and read.
5. Check and adjust your nautical chart
Once you have finished making your nautical chart, it is important to check and adjust it to ensure that it is accurate and easy to read. Compare it with other sources of information and check that all the information is correct. If necessary, adjust it to correct any errors or make it easier to read.
6. Save and use your nautical chart
Once your nautical chart is complete and verified, it is important that you keep it in a safe place so that you can use it again in the future. If you don’t have it in electronic format, we recommend scanning your chart and saving a digital copy for use on a GPS device or tablet.
In summary, it is very important to have and know how to use a nautical chart when sailing to ensure safe and efficient navigation. Making one is a process that requires time and attention to detail, but the end result is a valuable tool for any sailor.
If you follow the steps outlined above, you will be well on your way to making an accurate and useful nautical chart. Now that you know all the information, explore your different boating options and apply this information to your next Motyvel adventure.
