Each week, Bateaux.com offers you a question about the boat license. To validate your knowledge or to discover unexplored areas. This week, we tackle a question about lights and marks on ships.
An array of lights
If we see three red lights superimposed, we are in the presence of a vessel handicapped by its draught. The RIPAM gives the following definition for this type of vessel: The term "Draught Handicapped Vessel" refers to any mechanically propelled vessel which, because of its draught and the available depth and width of navigable waters, has difficulty altering its course.
The two white lights, of which the one at the stern is higher than the one at the bow, indicate that we are in the presence of a ship of more than 50 m.
Finally the green light indicates that we see the starboard side of this boat.
In our picture, the boat is going from the left to the right. To avoid it and not to disturb it, it is advised to pass on its back, thus to go towards the left of the picture.
Seen from above, this gives the illustration above. I'm on boat A and I can see the ship in front of me moving in the direction of the red arrow.
