Marking, the isolated danger mark

The isolated hazard mark indicates a hazard that can be bypassed on either side.

As its name suggests, the isolated hazard mark indicates a hazard that is isolated in the middle of clean water. Faced with a brand like this, it can be avoided by bypassing it without any obligation as to the side chosen.


The Ant in Lavandou Bay

These marks are erected either as a turret directly on the rock, or as a wet buoy in way of danger.

The 2 spheres well separated one from the other are often the most visible to distinguish this type of buoy.

Colour Several red and black stripes
Indicator Two superimposed black spheres
Fire (if any) 2 white flashes grouped together

Mnemonic technique
