What is the purpose of a "securite" call?

The purpose of a "securite" call is to communicate non-urgent navigation safety information. This type of call is used in maritime communication to provide important information related to the safety of navigation that does not require an immediate response. For instance, it may relate to hazards in a particular area, weather updates, or other notices that would be beneficial for all boaters in that vicinity. This helps ensure that everyone navigating the waters is informed and can take appropriate actions to maintain safety, thereby enhancing overall maritime safety without the urgency that a distress call (such as a "mayday") or a call indicating immediate risks might demand.
