Thanks to many years of experience in commercial fishing and navigation in these waters we recommend you to consider our suggestions.
There are the left and right hollows that protect the entrance canal against coastal erosion. These hollows are noticeable only when a water level is very low, i.e. in September and October. In this case they are seen as hidden submerged obstacles which during the main period of navigation damage the propellers of the ships that enter the territory and yacht keels.
