Maritime symbols are visual representations used in navigation and communication at sea. These symbols can be found on nautical charts, flags, and buoys, helping sailors understand important information about water conditions, hazards, and navigational routes. For example, a red buoy typically indicates a danger area, while a green buoy marks safe passage. In addition to navigation, maritime symbols are also used in signaling between ships. The International Code of Signals employs flags to convey messages about a vessel's status or intentions. Understanding these symbols is crucial for safe and effective maritime operations.
