Sailing Navigation - Beacons & Buoyage Devices
After knowing the different concepts of Sailing Navigation, the next step is to get familiar with the tools and devices. In the previous section - Navigation Tools, you will notice that Navigation requires several gadgets, most of which are electronic ones.
There are other devices or instruments that will be added to the list. These instruments will also aid you in navigating. In this section, know what these devices are and learn how they can help in your work:
Beacons
A Beacon, whether lighted or not, is a fixed aid to Navigation set up at a conspicuous position. It can be a Lighthouse, lights (lighted), or daybeacons (unlighted).
A Lighthouse is a structure or tower which is used to indicate hazardous coastlines and maintain safe entries to harbors.
Each light sequence from a Beacon conveys relevant information. Thus, it is important to pay attention and know the meanings of various light sequences. The light on the Beacon will be able to help you in determining your position.
Buoyage Devices
The International Association of Lighthouse Authorities or IALA has a system of Buoyage which aid sailors as far as Pilotage and Navigation are concerned. Take note that there are two IALA systems employed.
IALA System A (port lateral marks - red, starboard lateral marks - green) is used in countries such as Africa, Australia, India, and many Asian countries. On the other hand, IALA System B (port lateral marks - green, starboard lateral marks - red) is used in the Philippines, Korea, and in many parts of America.
Sailboats can avoid dangers, channels, and other obstructions through aids of Navigation which are floating in the water. These are called Buoys. A Buoy has many purposes. Depending on the features, it can be used to mark a location, indicate a channel, or warn vessels of dangers.
They come in a variety of colors, shapes, and light. The features of each Buoy convey a particular message.
As defined by IALA, a Lateral Mark indicates the edge of a channel. On the other hand, a Cardinal Mark indicates hazardous areas and where safe water is. You can take note of it no matter what position you are in.
These are the additional devices which will aid you in Navigation. Make sure to know what message each type of Beacon or Buoy conveys in order to avoid problems and hazards while on the water.
