The basics of maritime signalling
The coast is a regulated area: following the rules is a matter of safety.
The signage aims to show sailors and swimmers where there are dangers, in particular invisible ones covered by the sea.
1- Beach and swimming markers (in the band of sea that is within 300 metres of the coast)
The coastal protection zone is limited to 300m from the shore. The purpose of the markers is to signal hazards, particularly those hidden below the water surface, as well as the navigation channels, to seafarers.
1. Port (left) approach channel buoys
2. Starboard (right) approach channel buoys
3. Demarcation buoys for swimming areas and the 300m zone.
300 metre coastal zone:
When you enter this zone, vehicle speed should not exceed 5 knots (9km/h). Sailboats and motorboats must follow the approach channels.
No boats or fishing are allowed in the marked swimming areas within the 300 m of the coastline.
2- Lateral markers:
They mark the harbour entrance:
- the red light or marker to the left, to: PORT
- the green light or marker to the right, to: STARBOARD
3- Cardinal markers
They indicate the position of a hazard (shallows, rocks, etc.). Each cardinal mark has a distinctive colour and sequence of flashing light.
4- Isolated danger markers
They mark a specific, hidden danger of limited size. You need to move far away from this marker when you come across it, because the hazard is located close to it.
5- Special markers
They indicate a forbidden zone (generally zones where there are underwater cables, military zones, etc.)
