Visual Signaling
In the maritime context, visual signaling refers to the use of visual aids to communicate between vessels, or between a vessel and shore. This can include a wide range of methods, such as the use of flags, lights, shapes, and semaphore. Visual signaling is an essential part of navigation and safety at sea. For instance, the International Code of Signals, which is an internationally recognized system of signals, uses a set of flags that represent different letters of the alphabet, numbers, and specific messages. These can be used to communicate a wide range of information, such as the vessel's position, course, speed, and any potential dangers or emergencies. Similarly, lights and shapes can be used to indicate the status of a vessel, such as whether it is at anchor, not under command, or engaged in fishing. Semaphore, on the other hand, is a system of sending messages by holding the arms or two flags in certain positions according to an alphabetic code. Despite the advent of modern communication technologies, visual signaling remains a vital part of maritime communication due to its reliability and simplicity.
