What is the purpose of a racon buoy?

A racon buoy serves a specific role in enhancing maritime navigation by transmitting radar signals. When a vessel approaches a racon buoy, the buoy emits a distinct radar signal that is identifiable on the ship's radar system. This allows mariners to pinpoint their location relative to the buoy, thereby assisting in navigation, especially in areas where visual references may be minimal due to weather or darkness.

In situations where the identities of buoys and other navigational aids may be unclear, a racon buoy's radar return provides crucial information. By offering this radar guidance, the racon buoy significantly contributes to safe navigation and helps mariners avoid dangers or navigate through complex waterways. This function distinguishes racon buoys from other types of navigational markers, which may serve different purposes, like marking shipping lanes or warning of hazards.
