Boating license / On this picture, what are the windward and leeward sides of the sailboat?

We often speak of "leaving a leeward buoy". Or to "pass to windward of another boat". But what do these expressions mean? On our photo, which side is to windward of the sailboat: side A? Side B?

Each week, Bateaux.com offers you a question about the boat license. To validate your skills or even to discover unexplored areas. This week, we tackle a question about the weather.

On our picture which side is upwind of the sailboat?

To get the right answer, you had to answer B. It is the place where the B is located which is upwind of our sailboat.

To be upwind of an object or boat (this is true for a motorboat as well as a sailboat) means that it is on the side from which the wind is blowing. On the contrary, being downwind means that it is on the opposite side of the wind. We have materialized the wind by the big red arrow on our picture. Our sailboat receives the wind on its port side, so it is its windward side.

On this other picture, this ketch is passing under our wind.
