     You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be

strong. But you need to be quick. And you need to understand a few basic rules about the wind.

     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 the 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 (角度)

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 ° angle to the boat. It needs to be out far enough to catch

the wind, but it shouldn't flap (摆动). It shouldn't look like on a flagpole. If it is flapping, 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 another. This is called tacking. When you are tacking, you must always keep the sail inside

the boat.
