Each week, Bateaux.com offers you a question about the boat license. To validate your skills or even to discover unexplored fields. This week, we tackle the question of maritime buoyage.
First of all, we must recognize this beacon. Still quite far away, it is difficult to visualize the triangles which are on its top. But its black-yellow-black color informs us precisely. It is an East cardinal.

As a reminder, let's remember that the two triangles that characterize a cardinal have the points directed towards the black color. Here, we have two triangles with opposite points. We can write an E in these 2 triangles, giving a mnemonic means to remember the name of the cardinal.
A cardinal protects an obstacle (pebble, rocky point...). They are distributed around the obstacle, the East cardinal will be to the East of the obstacle. Thus, by passing to the East of the cardinal one avoids the danger.

In our situation, the sailboat that is heading North and leaving the cardinal on port side will pass well to the East of the cardinal. It is therefore in the right situation and can continue its route without risk.
