“Where there be dragons” is a phrase historically used on maps to indicate unexplored or dangerous territories. It symbolizes the unknown and the potential risks associated with venturing into unfamiliar areas. (https://en.wikipedia.org)
At EDYC a most frequented sketch is that of our racing marks

Note – above not to be used for navigation. NB – the race marks are not there in winter !
We have customarily used poles ( scaffolding poles (perches)) placed on rocks or pladdies to indicate their presence however a more informative mark is that of the cardinal mark system

In this the top of the pole indicates where the danger is and where safer water is.
Cardinal Marks
Wikipedia explains that cardinal marks are a style of sea (navigation) mark commonly used in maritime pilotage to indicate the position of a hazard and the direction of safe water. These cardinal marks indicate the direction of safety. Giving a cardinal direction (one of the four main compass directions) relative to the mark. This makes them meaningful regardless of the direction or position of the approaching vessel,

Here is a picture of a cardinal mark
