First, you must ask yourself, "Where is the wind coming from? Is it coming from ahead or behind or from the side?" You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90°angle(角)to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°an-gle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(擺動).It shouldn't look like a flag on a flagpole. If it is flap?ping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can't go in a straight line. You must go first in one direction and then in anoth?er. This is called tacking. When you are tacking, you must always keep the sail inside the boat.
