The Importance of Morse Code and Visual Communications in the Maritime Industry

Learning visual communications is a key tool for mariners to have in case of technical or frequency issues with radio equipment, as well as to eliminate language barriers. Vessels within adequate range of each other may communicate using flashing lights, sound signals, or code flags.

As a mariner, it is important to learn Morse Code in order to communicate with vessels that may be several miles away from each other and to be able to communicate day and night. Knowing the importance of visual communications, Northeast Maritime Institute has developed the HALO° Flashing Lights Simulator which will help you practice and learn Morse Code, for free!

In addition to the simulator, we are providing flashcards and material within the Visual Communications course for purchase in order to receive a certificate, all powered by Northeast Maritime Online (NEMO°). To learn more about the certification course, visit
