All navigation supports, specifically all systems meant to support navigators at sea, can be classified as:

  1. Maritime Signalling: Lighthouses, Lights, Foghorns, and Day Signallings, that can be perceived through sight and hearing;
  2. Radioelectric Instruments: Maritime Radiobeacons and Racons, which can only be used by means of receivers, such as radio-goniometers and radars.

The maritime signallings, scattered along the coasts of our peninsula and islands, work as reference points to navigators while sailing with the coast in sight.
In fact, they:

  • are located in a known and determined position, whose bearings can be taken from the nautical chart;
  • can be easily identified and recognized from the sea.

The maritime signallings are positioned in relation to their specific function: support to coastal navigation, landing, in and out of ports, to signal a single danger, to delimit a navigable channel; etc.

Each maritime signalling (optical or audible), as well as all navigation supports, can be identified thanks to a specific characteristic.
