Maritime signals are visual or auditory communications used by ships and boats to convey important information at sea. These signals can include flags, lights, and sound signals, helping vessels communicate their intentions, warnings, or navigational information to one another. The International Code of Signals (ICS) provides a standardized system for these communications, ensuring that mariners from different countries can understand each other. In addition to flags and lights, sound signals like horns or whistles are also crucial in maritime communication, especially in foggy conditions. These signals help prevent collisions and ensure safe navigation in busy waterways. Understanding and using maritime signals is essential for all seafarers to maintain safety at sea.
