Preface:

How do sailboats use the wind to sail?
Heading with the wind should be the most normal way of sailing in the minds of most people. The wind comes from behind, pushing the ship forward, just as people say 'a smooth sailing'.
When sailing into the side wind, the wind from the side becomes two forces, one is the force that makes the boat sidle, and the other is the force that makes the boat move forward. The sidling force is transformed into the force of side-fall by the "center board", and then the center of gravity of the sailors is adjusted to counteract, leaving only a very small side force, which is called Leeway, while most of the force is forward, which is the side wind sailing.
The limit angle for sailing into the wind is about 35 degrees on either side of the direction of the wind, but generally, 45 degrees is considered the limit. This is greatly influenced by the design of the boat. The concept of sailing into the wind is very similar to sailing with a side wind, but when sailing into the wind, the lateral force is greater, and the forward force is less than with a side wind.
Understanding how sailboats sail in different wind directions, let's get started making an interesting wind-powered sailboat together.
