Every week, we present you with a question about your boating license. Whether you're looking to validate your knowledge or discover new and unexplored areas. This week, we take a look at a question on ship's lights and markings.
Among the myriad of lights that can be distinguished in this situation, some serve as on-board lighting for life on the boat, while others are ship's lights and markers. For example, we can single out a red light and a green light, placed on each side, as well as two superimposed white lights.
Seen from the air, a motorboat over 50 m in length must show :
- A masthead light at the front
- A second masthead light behind and higher than the first
- Red and green sidelights
- A white stern light

The green and red lights indicate that the boat is coming towards us. We're exactly on course. If we were a little to one side, we'd see only one colored light, green or red, depending on the tack.
The two superimposed white lights indicate that this is a motorboat and that it is over 50 m long. The lower light is at the bow, while the upper one is at the stern.
For this boating license question, answers C and D had to be validated.
